Recommendations on generic names competing for use in Leotiomycetes (Ascomycota)

Abstract

In advancing to one scientific name for fungi, this paper treats genera competing for use in the phylogenetically defined class Leotiomycetes except for genera of Erysiphales. Two groups traditionally included in the so-called “inoperculate discomycetes” have been excluded from this class and are also not included here, specifically Geoglossomycetes and Orbiliomycetes. A recommendation is made about the generic name to use in cases in which two or more generic names are synonyms or taxonomically congruent along with the rationale for the recommendation. In some cases the recommended generic name does not have priority or is based on an asexual type species, thus needs to be protected and ultimately approved according to Art. 57.2 of the International Code of Nomenclature for algae, fungi and plants (ICN). A table is presented listing all competing generic names and their type species noting the recommended generic name. New combinations are introduced for the oldest epithet in the recommended genus including Ascocalyx berenice, Ascoconidium purpurascens, Ascocoryne albida, A. trichophora, Blumeriella filipendulae, B. ceanothi, Botrytis arachidis, B. fritillariae-pallidoflori, Calloria urticae, Calycellina aspera, Dematioscypha delicata, Dermea abietinum, D. boycei, D. stellata, Diplocarpon alpestre, D. fragariae, Godroniopsis peckii, Grovesinia moricola, Heterosphaera sublineolata, Hyphodiscus brachyconium, H. brevicollaris, H. luxurians, Leptotrochila campanulae, Monilinia polystroma, Neofabraea actinidae, N. citricarpa, N. vagabunda, Oculimacula aestiva, O. anguioides, Pezicula brunnea, P. californiae, P. cornina, P. diversispora, P. ericae, P. melanogena, P. querciphila, P. radicicola, P. rhizophila, Phialocephala piceae, Pilidium lythri, Rhabdocline laricis, Streptotinia streptothrix, Symphyosirinia parasitica, S. rosea, Unguiculariopsis caespitosa, and Vibrissea laxa.

Fungi on stems and twigs in initial and advanced stages of dieback of European ash (Fraxinus excelsior) in Poland

“…The former (anamorph: unknown) occurs on branches and bare wood of trees and shrubs (Sutton 1980;de Gruyter et al 2010). The latter is an anamorph of the discomycetous genus Tympanis (Johnston et al 2014).…”

Sexual and asexual states of some endophyticPhialocephalaspecies ofPicea

“…For example, sequences attributed to M. cinerea currently in GenBank probably represent several distinct and distantly related species based on their dissimilar ITS sequences. Genetic and morphological links with several other teleomorph genera also have been indicated, including Phaeomollisia (Johnston et al 2014) and Vibrissea (Hamad and Webster 1988, Wang et al 2006b, Grünig et al 2009). Consequently mollisoid apothecia may be candidate sexual states for some endophytes known only by their asexual morphs or sterile cultures.…”

“…Jacobs et al 2001, Day et al 2012. Phaeomollisia piceae recently was combined into Phialocephala based on phylogenetic placement within a major clade of Phialocephala (Johnston et al 2014), resulting in 29 currently accepted species in this genus (Index Fungorum 2015, Wong et al 2015.…”

Chlorovibrissea korfii sp. nov. from northern hemisphere and Vibrissea flavovirens new to China

“…Kendr. known only by asexual states, are also included in the family (Kirk et al 2008;Johnston et al 2014). Acephala was erected for the non-sporulating species of Phialocephala that contain a small group of dark septate root endophytes (Grünig and Sieber 2005;Grünig et al 2008;Grünig et al 2009;Münzenberger et al 2009;Wang et al 2009;Day et al 2012).…”

“…Acephala was erected for the non-sporulating species of Phialocephala that contain a small group of dark septate root endophytes (Grünig and Sieber 2005;Grünig et al 2008;Grünig et al 2009;Münzenberger et al 2009;Wang et al 2009;Day et al 2012). About 80 species are currently accepted in the family, among which two species are in Acephala, six in Chlorovibrissea, one in Leucovibrissea, 33 in Phialocephala, and 36 in Vibrissea (Grünig et al 2008;Kirk et al 2008;Grünig et al 2009;Münzenberger et al 2009;Wang et al 2009;Day et al 2012;Johnston et al 2014;Sandoval-Leiva et al 2014;Index Fungorum 2017). The previous phylogenetic studies on the vibrisseaceous fungi showed that Chlorovibrissea and Vibrissea are not closely related, and the family was presumably polyphyletic (Wang et al 2006;Sandoval-Leiva et al 2014).…”
