*2.7. Cornus*

The genus *Cornus* (Cornaceae) consists of over 50 species of woody plants, many of which are cultivated as ornamental and medicinal trees [93]. The most widespread ornamental plants of the genus are *C. florida* and *C. stolonifera*, called the flowering dogwood, native to northern and central America [93]. The species *C. o*ffi*cinalis* is widely distributed in China, Korea, and Japan, and used for its several pharmacological activities. Among bioactive compounds, iridoids, tannins, and flavonoids are the major components [94].

About 90 fungal endophytes have been isolated and identified from *C. alba*, *C. alternifolia, C. stolonifera, C. controversa,* and *C. o*ffi*cinalis* collected in Canada, USA, Japan, China, and Korea (Table 8): *Penicillium* (8 isolates)*, Fusarium* (4 isolates)*, Cladosporium* (5 isolates), *Colletotrichum* (5 isolates), *Alternaria* (6 isolates), *Pestalotiopsis* (5 isolates), *Aureobasidium* (4 isolates), *Botryosphaeria* (3 isolates), *Cryptodiaporthe* (2 isolates), *Phomopsis* (3 isolates), *Talaromyces* (4 isolates), *Aspergillus* (3 isolates), *Discula* (4 isolates), *Diaporthe* (3 isolates), *Neonectria* (2 isolates), *Trichoderma* (2 isolates), *Tubakia* (2 isolates), and *Didymella* (3 isolates). Only one isolate of the following genera has been reported: *Ascochyta*, *Botrytis*, *Cyrptosporiopsis*, *Elsinoe*, *Epicoccum*, *Helminthosporium*, *Lecanicillium*, *Leptosphaerulina*, *Lophiostoma*, *Drepanopeziza*, *Nigrospora, Sarocladium, Cordyceps*, *Phyllosticta*, *Phytophthora*, *Phoma*, *Pleuroceras*, *Thelonectria*, *Sclerotinia*, *Neofabraea*, *Septoria*, *Simplicillium*, *Stenella*, *Verticillium,* and *Xylaria.*

## *2.8. Hamamelis*

*Hamamelis* (Hamamelidaceae), commonly known as witch hazel, comprises six species of ornamental shrubs. This genus is distributed across North America and eastern Asia. Bark extracts contain proanthocyanidins and polyphenolic fractions, with medicinal properties [107,108].

Fungal endophytes belonging to genera *Colletotrichum*, *Nigrospora*, *Pezicula*, and *Phyllosticta* have been isolated from *Hamamelis* plant tissues in the USA, China, Netherlands, Canada, and Japan (Table 9).
