Special Issue Information

Dear Colleagues,

Leotiomycetes is one of the most diverse groups within Ascomycota but less than 7% of its diversity is currently known. While previously assumed to be mainly composed of saprobes or pathogens, it is becoming clear that this class also encompasses a variety of symbiotic fungi occupying many different terrestrial and aquatic ecological niches. While typically conceived as comprising apothecial fungi, Leotiomycetes also includes lineages with closed ascomata or those that produce naked asci and many anamorphic lineages. Their small size, the difficulty in correctly identifying them, and the consequent neglect by most mycologists have hindered efforts to sort this class and accurately assess the ecologies and relationships of members. The objective of the proposed Special Issue of Journal of Fungi, in the Section Fungal Evolution, Biodiversity and Systematics, is to bring together high-quality revisions and novel studies that advance the modern understanding of Leotiomycetes. This Special Issue will cover many research areas, including the description of new fungi, revisions of existing taxa, DNA barcoding, phylogenetic and morphological studies on evolution and relationships among taxa, methodologies for species delimitation, tools for identification, reports from underrepresented geographical regions, ecological studies, reconciliation of teleomorphic and anamorphic lineages, and related studies that bring focus to the class.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Journal of Fungi is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The apothecial fungus Ramomarthamyces octomerus sp. nov. is described from specimens collected in Mediterranean climate regions in southern Portugal, Spain (Canary Islands), and the Dalmatian region of Croatia. Presumably saprobic, R. octomerus occurs on intact, decorticated wood of Laurus novocanariensis and Olea europaea [...] Read more.
The apothecial fungus Ramomarthamyces octomerus sp. nov. is described from specimens collected in Mediterranean climate regions in southern Portugal, Spain (Canary Islands), and the Dalmatian region of Croatia. Presumably saprobic, R. octomerus occurs on intact, decorticated wood of Laurus novocanariensis and Olea europaea. Ascospores are cylindric-ellipsoid and seven-septate. Surprisingly, in our four-locus phylogenetic analysis (nuSSU, ITS1-5.8S-ITS2, LSU, mtSSU), this fungus clusters among species of Cyclaneusma, Marthamyces, Naemacyclus, and Ramomarthamyces in a core Marthamycetaceae clade that circumscribes primarily leaf-inhabiting, filiform-spored species. In addition, the asci of R. octomerus possess an amyloid pore, but the reaction varies between specimens collected in the Canary Islands and those collected in Portugal and Croatia. The occurrence of an amyloid reaction in the asci of R. octomerus challenges the characterization of Marthamycetales taxa as possessing inamyloid asci. In our discussion we provide background and analysis of these notable observations. Full article
