The Genera of Fungi: fixing the application of type species of generic names

et al. 2014

To ensure a stable platform for fungal taxonomy, it is of paramount importance that the genetic application of generic names be based on their DNA sequence data, and wherever possible, not morphology or ecology alone. To facilitate this process, a new database, accessible at www.GeneraofFungi.org (GoF) was established, which will allow deposition of metadata linked to holo-, lecto-, neo- or epitype specimens, cultures and DNA sequence data of the type species of genera. Although there are presently more than 18 000 fungal genera described, we aim to initially focus on the subset of names that have been placed on the “Without-prejudice List of Protected Generic Names of Fungi” (see IMA Fungus 4(2): 381–443, 2013). To enable the global mycological community to keep track of typification events and avoid duplication, special MycoBank Typification identfiers (MBT) will be issued upon deposit of metadata in MycoBank. MycoBank is linked to GoF, thus deposited metadata of generic type species will be displayed in GoF (and vice versa), but will also be linked to Index Fungorum (IF) and the curated RefSeq Targeted Loci (RTL) database in GenBank at the National Center for Biotechnology Information (NCBI). This initial paper focuses on eight genera of appendaged coelomycetes, the type species of which are neo- or epitypified here: Bartalinia (Bartalinia robillardoides; Amphisphaeriaceae, Xylariales), Chaetospermum (Chaetospermum chaetosporum, incertae sedis, Sebacinales), Coniella (Coniella fragariae, Schizoparmaceae, Diaporthales), Crinitospora (Crinitospora pulchra, Melanconidaceae, Diaporthales), Eleutheromyces (Eleutheromyces subulatus, Helotiales), Kellermania (Kellermania yuccigena, Planistromataceae, Botryosphaeriales), Mastigosporium (Mastigosporium album, Helotiales), and Mycotribulus (Mycotribulus mirabilis, Agaricales). Authors interested in contributing accounts of individual genera to larger multi-authored papers to be published in IMA Fungus, should contact the associate editors listed below for the major groups of fungi on the List of Protected Generic Names for Fungi.

“…Although conidium development in Chaetospermum was investigated in previous studies (Fonseka 1960, Nag Raj 1964, it was not yet classified with the standard terminology as sympodial and postsomatogamic. Since conidia are produced in slimy masses, they may serve for passive short-distance dispersal by water, whereas the actively discharged basidiospores may be responsible for the widespread occurrence in different regions and in diverse plant associations (Weiß et al 2011).…”

“…notes: Fonseka (1960) and Nag Raj (1964) also indicated the lateral displacement of the conidium base as well as elongation of conidiogenous cells and successive production of two or more conidia at different conidiogenous loci at the apex of the conidiogenous cell. We conclude that this conidiogenesis can be classified as sympodial.…”

“…The cell components in conidia at later stages of development could be interpreted as several nuclei or vacuoles and could not be resolved anymore in mature conidia with fully developed appendages. The formation of transversal septa prior or during germination shown by Fonseka (1960) indicate that mitotic divisions took place so that conidia could become multinucleate and after that multicellular at a late ontogenetic stage.…”

Two specimens of Sebacinales from Panama and Taiwan were identified based on morphology and partial LSU rDNA sequences. A specimen on oak fruits from Panama was identified as Chaetospermum camelliae, which contained an Efibulobasidium teleomorph. Conidiogenesis in this species is classified as postsomatogamic and sympodial. For a specimen from Taiwan, a new species of Globulisebacina is described based on its placement in a molecular phylogeny of partial LSU rDNA sequences, two-celled basidia and lack of a Chaetospermum anamorph. Nomenclatural errors of two recently newly combined Sebacina species are corrected.
