Abstract
:The species of Gymnopilus (Hymenogastraceae, Agricales) are commonly recognized as wood-decaying fungi. Certain members of this genus have been identified as psilocybin-producing mushrooms. Gymnopilus exhibits a diverse range and has a global distribution. In this study, a total of seventy-eight specimens were gathered from ten provinces in China. A comprehensive molecular phylogenetic analysis was conducted, employing gene sequences including ITS, nrLSU, nrSSU, rpb1, rpb2, and tef1-α. Additionally, morphological examinations were also carried out. The phylogenetic topology of Gymnopilus from this study generally agreed with previous studies and facilitated the identification of all those specimens. As a result, eleven species, including five newly discovered ones named Gy. gyirongensis, Gy. variisporus, Gy. tomentosiceps, Gy. tenuibasidialis, and Gy. aurantipileatus, were recognized. Significantly, four of the five newly identified species are native to the Xizang Autonomous Region, emphasizing their specialization in this distinctive habitat. This research contributes to our comprehension of Gymnopilus diversity and lays the groundwork for the conservation and sustainable utilization of Gymnopilus resources.
1. Introduction
The genus Gymnopilus P. Karst. (Hymenogastraceae, Agaricales), which was originally described in Sweden in 1879, has more than 200 species in the world [1,2,3]. The species of Gymnopilus are commonly known as wood-decaying fungi in forests and play the role of decomposers in the cycle of matter [1,4]. Gymnopilus species can be characterized by the morphological characteristics of their hemispherical or convex cap; yellowish, brownish, greenish, or purplish pileus; adnate or adnexed lamellae; fibrous and sometimes membranous or filamentous curtain; the presence of an arachnoid to membranous veil; roughened or verrucose appearance; and basidiospores that are yellow to yellowish brown and then rusty brown. Some species usually have a bitter taste and clamp connections present on almost all kinds of hyphae [5,6,7,8,9]. The majority of Gymnopilus species are saprobes, and some species generate psilocybin, a psychedelic compound that can lead to nerve poisoning [7,10].
Romagnesi (1942) first divided the genus into two groups: Annulatae Romagn. (1942: 89) and Cortinatae Romagn. (1942: 89). Group Annulatae is characterized by having a persistent, membranous annulus, while in the other group, the annulus is absent. Hesler (1969) and Singer (1986) accepted those two groups of Gymnopilus and put this genus under Cortinariaceae, while Kühner (1980) and Guzmán-Dávalos et al. (2003) classified it under Strophariaceae. Kirk et al. (2008) considered it to belong to Hymenogastraceae [1,2]. Later, Guzmán-Dávalos (1995) established a section, Macrospori Guzm.-Dáv (1995: 119) to Gymnopilus, which contains species characterized by large spores and a lack of an annulus [7,11]. Recently, morphological examination combined with molecular phylogenetic analysis has been widely used to study this genus and describe new species from different parts of the world [2,12,13,14,15,16,17,18,19,20].
The taxonomic study of Gymnopilus started relatively late in China, and Shu-Qun Deng (1963) was the first person to record Gymnopilus species from China in his monumental work Fungi of China. Recently, Li (2012) reported a total of thirty Gymnopilus species, including six new species from the tropical region [7,21]. Liu (2019) reported a species from northeast China, and she also constructed a phylogenetic tree of Gymnopilus based on ITS sequences. This phylogenetic tree, which was identical to those of previous studies, showed six stable clades [5,7,12]. In terms of geographic distribution, most Gymnopilus species were found in parts of southern China, such as the Guangdong, Yunnan, Sichuan, and Hainan provinces, and some were from northeastern China (Jilin province). Generally, the species of Gymnopilus in China is poorly reported, and up to now, only thirty-one species have been recorded [7,21].
In this study, we collected seventy-eight Gymnopilus specimens from ten provinces of China and two from Thailand. Molecular phylogenetic analysis combined with morphological examination revealed they belong to eleven species, of which five are proposed as new species.
2. Materials and Methods
2.1. Specimen Collection and Morphological Study
We collected specimens in the field from the Xizang Autonomous Region and surrounding provinces of China and Thailand. The macroscopic features of the collected specimens were photographed and recorded, along with their odor and the fresh specimens’ changes in color upon injury. The specimens were dried completely overnight at 55 °C using a food desiccator, sealed in plastic bags, and deposited in the Herbarium Mycologicum Academiae Sinicae, Beijing, China (HMAS).
The anatomical and cytological features, including lamellae, pileipellis, basidiospores, basidia, and cystidia, of the dried specimens were observed following the protocols described in [22]. For microscopic characterization, the sections were mounted in 5% KOH solution. Thirty measurements of mature spores were taken for each specimen, along with twenty measurements of basidia and cystidia, which included x, the mean of length by width ± SD; Q, the quotient of basidiospore length to width; and Qm, the mean of Q-values ± SD [23]. The hymenial cystidia and pileocystidia were stained with 1% aqueous Congo red solution [24]. The color designation referred to methuen handbook of colour.
2.2. DNA Extraction, PCR Amplification, and Sequencing
Genomic DNA was extracted from 5 to 10 mg of dried specimen using a Broad-spectrum Plant Rapid Genomic DNA Kit (Biomed, Beijing, China) and preserved at −20 °C.
We used primers ITS4 and ITS5 [25] for the internal transcribed spacer (ITS) region of the nuclear ribosomal DNA repeat, primers LROR and LR5 [26] for the Large Subunit (LSU) region, primers NS1 and NS4 [27] for the nuclear nrSSU-rDNA region, primers EF1-983F and EF1-1567R [28] for translation elongation factor alpha (tef1-α), and RNA polymerase II gene (rpb2) with 6F/7CR [29] and primers Af/Cr for RNA polymerase II (largest subunit) (rpb1) [30]. Genes were amplified by polymerase chain reaction (PCR) using the procedures mentioned in [26,28,29,31]. The PCR products were sent to a commercial biotech company (Baimaide Biotechnique Company, Beijing, China) for sequencing.
2.3. Molecular Phylogenetic Study
The sequences produced from this study and some generated by a previous work and deposited in the NCBI GenBank database were used in our phylogenetic analyses [2,7,9,19,20,32,33] (Table 1). Sequences of multigene data were aligned separately using Muscle version 3.6 [34], then manually adjusted to remove ambiguous regions in BioEdit version 7.0.4 [35]. The six partitions were assembled in PhyloSuite v1.2.2 [36] in the order of six loci (ITS, nrLSU, nrSSU, rpb1, rpb2, tef1-α). Maximum likelihood (ML) analysis was performed using RAxmlGUI 1.3 under a GTRGAMMA model with one thousand rapid bootstrap (BS) replicates [37]. Bayesian Inference (BI) analysis was performed using MrBayes v3.2.6 [38]. Six Markov chains were run for 2,000,000 generations, and trees were sampled every 100th generation. Burn-ins were determined in Tracer version 1.6 with an ESS value higher than 200, and the remaining trees were used to calculate Bayesian posterior probabilities (PP). The trees were displayed in Fig Tree version 1.4.0 [39].
A total of fifty-nine ITS sequences and four nrLSU sequences of Gymnopilus were downloaded from GenBank for phylogenetic analysis. Galerina marginata (Batsch) Kühner was selected as the outgroup. The newly generated sequence samples from this study have been deposited in GenBank.
The resulting file after tree construction was used to view the phylogenetic tree using iTOL [40]. Bootstrap Support (BS) ≥ 70% was considered significantly supported. Bayesian posterior probability (PP) ≥ 0.90 was regarded as significant.
3. Results
3.1. Molecular Phylogenetic Analysis Results
The seventy-eight specimens of Gymnopilus collected in this study, which represented eleven species, were included in the phylogenetic analyses with the outgroup species Galerina marginata. During our study, seventy-six ITS sequences, seventy-three nrLSU sequences, seventy-five nrSSU sequences, fifteen rpb1 sequences, sixty rpb2 sequences, and sixteen tef1-α sequences were newly generated in this study (Table 1). There was a total of five thousand and thirty-one bp (base pairs) in the final alignment after assembling those six gene sequences, of which eight hundred and ninety-one characters are from nrLSU, five hundred and forty-four characters are from tef1-α, seven hundred and six characters are from rpb2, one thousand three hundred and twenty-seven characters are from rpb1, eight hundred and ninety characters are from nrSSU, and six hundred and seventy-three characters are from ITS. The phylogenetic tree of the ML and MrBayes topology were generally the same using those six gene sequences. The Maximum Likelihood tree is shown in Figure 1, with bootstrap and posterior probability values indicated on the branches.

Notes: Gymnopilus gyirongensis sp. nov. can be easily distinguished by its orange-yellow to orange–brown pileus covered with yellowish rust squamules and umbonate center. Microscopically, this new species has medium-sized spores with moderately developed ornamentation. In the field, another proposed new species, Gy. tomentosiceps, may be confused with Gy. gyirongensis due to the fact that they both have yellowish caps; however, they have different habitats: Gy. tomentosiceps usually grows on mossy, soil under coniferous forest trees, but Gy. gyirongensis prefers fruiting on damp wood with rotting pine needles. In this study, phylogenetic analysis demonstrated that four specimens of this new species formed a cohesive cluster with full support. Additionally, they were positioned closely to Gy. penetrans, Gy. hybridus, and Gy. tomentosiceps (Figure 1). Gymnopilus penetrans is similar to Gy. gyirongensis because they share the characteristic of a smooth pileus covered with yellow and rusty brown squamules on the surface and can be found under conifers and deciduous trees [2,32]. However, Gy. penetrans develop bigger basidiopores (7.2–9.9 × 4–5.5 μm) than those of Gy. gyirongensis [6]. Moreover, these two species have 29 base pair differences in their ITS sequences. The four ITS sequences of this new species display four or five base pair differences. Another similar species, Gy. hybridus, can easily be distinguished from this species due to it having bigger basidiospores (6–8 × 4–4.5 μm) and basidia (20–28 × 5–8 μm) [5,7,41].

Other material examined: China, Xizang Autonomous Region, Shigatse, Gyirong County, Gyirong Town, N 28°23′45″, E 85°23′34″, 3441 m asl, 2 August 2022, collected by Mao-Qiang He and Bin Cao, ZRL20220830 (HMAS 287481).
Notes:Gymnopilus variisporus sp. nov. is distinctive in having a hemispherical to plano-convex pileus covered with yellowish squamules and possessing ellipsoid spores with moderate ornamentation. In the field, Gy. variisporus has relatively similar features to Gy. gyirongensis sp. nov. because they both possess yellowish pileus covered with rust squamules, but Gy. variisporus has bigger basidiospores (6.7–7.3 × 4.5–5.1 μm). Phylogenetic analyses in this study showed that Gy. variisporus formed a distinct lineage with fully supported values and was a sister to Gy. swaticus, Gy. stabilis, and Gy. sapineus (Figure 1). The three known species have bigger basidiospores and different habitats compared to this new species. Their respective characterization are Gy. stabilis having yellowish orange to light orange pilei and possessing bigger basidispores (7.5–8.5 × 4.5–5 µm), growing in sandy soil [32]; Gy. sapineus has yellowish brown to rusty brown pileus covered with fibrillose-tomentum to tomentum–scaly, and it possess bigger basidiospores (7.3–8.2 × 4.5–5.2 µm), fruiting on dead wood, but Gy. variisporus usually scatter or cluster in meadows, specifically on moist ground [6,32]; Gy. swaticus has velutinous to slightly tomentose and pileus and bigger basidiospores (8.6–10.0 × 4.5–5.6 μm), growing on Piceae smithiana [2,19].

Other material examined: China, Xizang Autonomous Region, Bomi County, N 29°47′30″, E 95°41′50″, 3670 m asl, 24 July 2021, collected by Xin-Yu Zhu, Ming-Zhe Zhang, ZRL20210795 (HMAS 287466).
Notes: Gymnopilus tomentosiceps sp. nov. is easily distinguished by its pileus, which is completely covered with a pale yellow tinge. In the field, Gy. tomentosiceps is morphologically similar to Gy. orientispectabilis because it possesses minutely fibrillose–scaly, but Gy. orientispectabilis has bigger basidiospores (7.2–9.0 × 4.8–6 μm) and basidia (22.2–36.0 × 6.6–9.6 μm) [20]. In the phylogenetic tree (Figure 1), Gy. penetrans and Gy. arenophilus are sisters to Gy. tomentosiceps, consistent with previous studies [2,7,41]. Morphologically, they can be easily distinguished. Gymnopilus penetrans has finely innately rusty ochre to rusty brown fibrillose-striped pileus and moderately developed ornamentation in terms of the ellipsoidal spores, growing on the dead wood of conifers and deciduous trees, and all of those are different from Gy. tomentosiceps. [2,32]. Gy. arenophilus differs by its bigger basidiospores (8.5–10.5 × 5.5–6.5 μm) and longer basidia (26–35 × 7–9 μm). Additionally, it exhibits distinct growing conditions, being found on sandy soil and occasionally attached to wood chips or charcoal [14].

Notes: Gymnopilus tenuibasidialis sp. nov. is easily distinguished by possessing abrupt papill pileus with brown patches and presenting slender cheilocystidia (30.1–35.5 × 3.7–4.8 μm). In the phylogenetic tree (Figure 1), Gy. tenuibasidialis formed a distinct lineage separated from other Gymnopilus species with fully supported lineages. Gymnopilus purpureosquamulosus, Gy. dunensis, Gy. suberis, and Gy. dilepis were close to this new species in phylogeny; however, they can be easily distinguished by macro- and micro-morphology. Gymnopilus dilepis can differ by its convex to plano-convex pileus with ruby to violet brown squamules, bigger basidiospores (6–7.5 × 4.8–6 µm), shorter and thicker cheilocystidia (20–30.2 × 8–12 µm) [12,42]. Gymnopilus purpureosquamulosus differs in having brown–purple to purple pileus with a central depression, a surface covered with reddish violet squamules and lamellae that turn grey with KOH and FeSO4, and bigger basidiospores (7–8 × 4–5.5 µm) [18]. Gymnopilus dunensis can differ by its pileus, covered with greyish squamules when young; bigger basidiospores (8.5–10.7 × 4.9–6.6 μm) and basidia (24.9–29.4 × 8.5–9.7 μm); and the fact that it is gregarious in small groups on sandy soil [19]. Gymnopilus suberis can differ by its pileus (initially cream to white before finally tunin sulfur yellow), a fibrous stipe with a cortinoid veil, and bigger basidiospores (7.2–8.8 × 4.4–4.8 µm) and basidia (24–27 × 6.5 µm) [17]. Phylogenetically, an unidentified specimen represented by ZRL20151336 (HMAS 287411) is a sister to this new species; however, they exhibit large differences in spore ornamentation (Figure 1).

Other material examined: China, Yunnan Province, Jingdong Yi Autonomous County, Ailao Mountains, N 23°36′–24°56′, E 100°44′–101°30′, 3166 m asl, 4 July 2021, collected by Rui-Lin Zhao, Mao-Qiang He, Ming-Zhe Zhang, Xin-Yu Zhu, and Mei-Qi Wang, ZRL20210364 (HMAS 287461).
Notes: Gymnopilus aurantipileatus sp. nov. is easily distinguished by having smooth to glabrous pileus and small cheilocystidia (9–16.5 × 3–4.8 μm). In the field, Gy. aurantipileatus sp. nov. is similar to Gy. purpureosquamulosus, because they both have pileus broadly convex to plano-convex, light orange to orange–yellow. Gymnopilus picreus and this new species have the type of same habitat, dead coniferous trees. However, Gy. picreus is distinguished by its squamulose pileus, rusty stained lamellae, dark brown stipe with white pulverulence, and bigger basidiospores (7.0–9.5 × 4.5–6.0 μm) [7]. Compared to Gy. crociphyllus, which has oxide yellow to light brown pileus and sometimes mustard yellowish smudges, bigger basidia (27.8–30.9 × 6.3–7.5 μm) and bigger cheilocystidia (23.3–26.9 × 6.7–8.7 μm) [43], Gy. aurantipileatus sp. nov. is also different. Gy. austropicreus differs by featuring a pale lemon-yellow pileus and lamellae that darken to black with the application of KOH. Furthermore, it possesses bigger basidiospores (6.6–9 × 4.5–6 µm) and cheilocystidia (15–27 × 4–6 µm) [44].

4. Discussion
Based on a combination of morphological and phylogenetic analyses, seventy-eight specimens were identified as eleven Gymnopilus species. Six of them are known species, and they are Gy. penetrans (Fr) Murrill, Gy. hybridus (Gillet) Maire, Gy. suberis (Maire) Singer, Gy. dilepis (Berk. & Broome) Singer, Gy. minisporus (T. Bau & M. T. Liu), and Gy. picreus (Pers.) P. Karst. These known species have been reported in tropical and subtropical areas based on previous studies [2,4,5,6,7,8,42,45], and in this study, we found them in ten provinces. Five new species—Gy. gyirongensis sp. nov.; Gy. tomentosiceps sp. nov.; Gy. variisporus sp. nov.; Gy. aurantipileatus sp. nov.; Gy. tenuibasidialis sp. nov.—mainly from the Xizang Autonomous Region and surrounding provinces of China have been described.
In this study, the macroscopic and microscopic morphology of those five new species are described in detail. Some macro- and micro-differences can be used to separate them from each other. Gymnopilus tomentosiceps is characterized by having a small and tomentose cap, while Gy. tenuibasidialis has an abrupt papilla cap. The mature spores of these five new species are all distinct, with suprahilar depressions in side view, but the shapes and ornamentation on the surface (Figure 2, Figure 3, Figure 4, Figure 5 and Figure 6) are different among these species. The basidiospores of Gy. variisporus and Gy. tomentosiceps are ellipsoid, while those of the other species are broadly ellipsoid; Gy. aurantipileatus has developed ornamentation on basidiospores, while the ornamentation of Gy. variisporus and Gy. aurantipileatus is very variable in the process of maturity (Figure 3 and Figure 6). In general, even though these five new species have similar macro characteristics, their characteristics in terms of spore shape and ornamentation are distinct and different from each other, as supported by our molecular phylogenetic analysis.
In the phylogenetic tree (Figure 1), twenty-nine included species of Gymnopilus segregate into three distinct clades (/penetrans, /crociphyllus, and /picreus), and these three clades are part of the six clades delineated in a previous study and are phylogenetically positioned in the same location [7,12]. In the /penetrans clade, Gy. hybridus is regarded as a synonym of Gy. penetrans by Holec (2005) [6]. However, in Europe, Gy. penetrans is classified as a singular species, with Gy. hybridus considered as a synonym [44,45], or as distinct and formed as two separate species (Gy. penetrans and Gy. hybridus) [46], and these species differ in color, the development of the veil, the presence of rusty spots on lamellae, and the shape of cystidia [6]. In our phylogenetic tree (Figure 1), Gy. tomentosiceps, Gy. hybridus, and Gy. penetrans show a close relationship but in different phylogenetic positions. Furthermore, a total of 21 nucleotide differences were detected in the ITS region between Gy. tomentosiceps and Gy. penetrans, and 24 nucleotide differences were detected between Gy. tomentosiceps and Gy. hybridus. Thus, those three species are identified as separate species. Differences in macro characteristics exist: Gy. prnetrans typically exhibits smooth or slightly wrinkled caps and stipe with white fibrillose partial veil remnants; Gy. hybrids feature hygrophanous streaks, as well as smooth and scale-free caps; and Gy. tomentosiceps is characterized by a cap covered with tomentose scales. Gymnopilus crociphyllus (Cooke and Massee) Pegler has distinctive characteristics, such as a fasciculate fruiting body, large pileus size, and a rumpled pileus margin [43]. In the /picreus clade, which includes Gy. austropicreus B.J. Rees and Gy. aurantipileatus sp. nov, this clade can be morphologcially characterized as having the same ornamentation on spores encased in a membrane which will gradually fall off with maturity. In another study [46], Gy. picreus (FT.) P. Karsten and Gy. austropicreus always emerged basal to the remainder of the species in the phylogenetic tree, which could refer to how they may be ancestral to other species in the genus [47]. Gymnopilus picreus groups grow as a saprophytes on the dead wood of conifers (mostly Picea abies; less frequently Pinus sylvestris) and, rarely, deciduous trees (Betula, Fagus sylvatica) [6], but other Gymnopilus species could grow on dead wood or on mulch-rich soil [2]. Thus, we suspect that the rationale for the types of wood rot they seek for nutrition is possibly ancestral in this genus.
In China, a total of thirty-one Gymnopilus species, including seven species originally described to be from China, have been published so far [7,9,21]. Gymnopilus is a species-rich genus, and the previous studies from China included several provinces, such as the Guangdong, Yunnan, Sichuan, Hainan, and Jilin provinces. In this paper, we have reported species from more parts of China, namely the Xizang Autonomous Region, resulting in a total of thirty-six species of Gymnopilus that have been recorded in China. Furthermore, four of the five new species are originally from the Xizang Autonomous Region, which indicates the special nature of the species, as they are from such a unique habitat. This study complements our understanding of Gymnopilus diversity and lays a foundation for the conservation and utilization of related Gymnopilus resources.
