“…canescens are lacking (Hughes 1979;Sivanesan 1983 (2014) introduced several lignicolous Helminthosphaeria species based on phylogenetic analysis and reported that the polyphyletic Helminthosphaeria has Diplococcium and Selenosporella asexual morphs in nature, but not con rmed by cultural characteristics or phylogenetic analysis. Helminthosphaeria is characterized by a fungicolous and lignicolous habit, super cial or immersed ascomata, cylindrical asci with hyaline to brown ascospores and associated asexual morphs with smooth-walled or verrucose, septate conidia (Samuels et al 1997;Réblová 1999a;Hernández-Restrepo et al 2017). In this study, the polyphyletic Helminthosphaeria is related to Endophragmiella dimorphospora and Hilberina species, and scattered in Helminthosphaeriaceae (Fig.…”

Sordariomycetes is an earlier and one of the widely distributed class of Ascomycota. The class was initially classified based on morphology in having inoperculate and unitunicate asci. With the development of DNA based phylogenetic analysis, several undetermined or polyphyletic members of Sordariomycetes were reclassified. However, not all species belonging to this class have been sequenced and analyzed. There are a number of species, especially those old and poorly studied ones which have never been sequenced before and not even recollected again for further taxonomic verification. One of the main objective in this study is to revise and update the taxonomy of several well-known old and poorly studied species whose classification are still obscure. Herein, we re-examined the type materials and/or authentic specimens together to explore 74 relatively poorly-studied genera, which mainly belong to Boliniales, Calosphaeriales, Chaetosphaeriales, Jobellisiales, and Sordariales classified under Diaporthomycetidae and Sordariomycetidae. We provide descriptions, notes, figures and/or drawings and discussed their phylogenetic relationships. As a result, the monotypic Jobellisiales is transferred from Hypocreomycetidae to Diaporthomycetidae. Based on phylogenetic analysis, the polyphyletic Lasiosphaeriaceae is divided into five families, Bombardiaceae (Apodospora, Bombardia, Bombardioidea and Fimetariella), Lasiosphaeriaceae (Anopodium, Bellojisia, Corylomyces, Lasiosphaeria, Mammaria and Zopfiella), Lasiosphaeridaceae (Lasiosphaeris), Strattoniaceae (Strattonia) and Zygospermellaceae (Episternus and Zygospermella). In addition, a new family Neoschizotheciaceae is established based on Neoschizothecium. Analysis of the type species of Boothiella, Stellatospora, Sulcatistroma and Tengiomyces placed them in Sordariaceae, Chaetomiaceae, Hypocreales and Coronophorales, respectively. We classify the genera lacking molecular data based on their morphology and expect them to be recollected; that is, Kacosphaeria in Calosphaeriales; Arnium, Biconiosporella, Camptosphaeria, Diffractella, Emblemospora, Eosphaeria, Periamphispora, Ramophialophora, Synaptospora and Tripterosporella in Sordariales; Conidiotheca in Sordariomycetes; Copromyces, Effetia, Endophragmiella and Tulipispora are accommodated in Ascomycota. Besides, we establish a new genus Neoschizothecium based on phylogenetic analysis. New combinations proposed include: Camaropella amorpha, Cam. microspora, Cam. plana, Cladorrhinum grandiusculum, Cla. leucotrichum, Cla. terricola, Cla. olerum, Helminthosphaeria plumbea, Immersiella hirta, Jugulospora minor, Lasiosphaeris arenicola, Neoschizothecium aloides, Neo. carpinicola, Neo. conicum, Neo. curvisporum, Neo. fimbriatum, Neo. glutinans, Neo. inaequale, Neo. minicaudum, Neo. selenosporum, Neo. tetrasporum, Neurospora autosteira, Podospora brunnescens, P. flexuosa, P. jamaicensis, P. hamata, P. macrospora, P. spinosa, Strattonia petrogale and Triangularia microsclerotigena, T. nannopodalis, T. praecox, T. samala, T. tarvisina, T. unicaudata, T. yaeyamensis. New epithets are proposed for Apiorhynchostoma apiosporum and Podospora dacryoidea.

“…Fusicoccum sp., a possible anamorph of Botryosphaeria , may also act as a multi-host endophytic fungus [ 58 ]. Furthermore, Diplococcium sp., such as D. heterosporum [ 3 , 59 ], and Exosporium sp., such as E. stilbaceum and E. ampullaceum co-occur with various fungicolous taxa [ 3 , 60 ]. Although Exosporium has been recently re-examined and re-described by Guatimosim et al [ 61 ], the taxa in this genus are frequently confounded with those of Cercospora and Helminthosporium [ 62 ], which are also known as fungicolous taxa.…”

“…described here possess unusual ascospores similar to those of Nectria lagodes and N. gynophila species [ 65 ], indicating that, eventually, mosses/bryophites growing on the edge of Tarcrust stroma may act as primary/secondary host species. Among the fungicolous pyrenomycetes found, there were Helminthosphaeria spp., such as H. corticiorum and H. fungicolous [ 59 ]. Various other fungicolous Insertae Sedis Petrakia sp., such as P. irregularis [ 17 ] pleosporaceous Pseudotrichia sp., such as Pseudotrichia mutabilis [ 17 ] and pleosporomycetous Tubeufia spp., such as T. cerea and T. brevispina [ 13 , 17 , 66 ] were found.…”

Natural Fungicolous Regulators of Biscogniauxia destructiva sp. nov. That Causes Beech Bark Tarcrust in Southern European (Fagus sylvatica) Forests

et al. 2020

Mycoparasites are a collection of fungicolous eukaryotic organisms that occur on and are antagonistic to a wide range of plant pathogenic fungi. To date, this fungal group has largely been neglected by biodiversity studies. However, this fungal group is of interest, as it may contain potential biocontrol agents of pathogenic fungi that cause beech Tarcrust disease (BTC), which has contributed to the devastation of European beech (Fagus sylvatica) forests. Biscogniauxia nummularia has been demonstrated to cause BTC. However, a trophic association between mycoparasites and pathogenic Biscogniauxia spp., has not been established. This study aimed to taxonomically identify and characterize Biscogniauxia, a fungus causing destructive BTC disease in European beech at Lovćen national park, Montenegro and to uncover the diversity of mycopathogens that are natural regulators of xylariaceous Biscogniauxia stroma formation, associated with beech decline. This finding is supported by distinctive phylogenetic and evolutionary characteristics, as well as unique morphological-microscopic fungal features indicating that Biscogniauxia from Montenegro, which is a major cause of BTC occurring in ancient beech forests at the edge of southern Fagus sylvatica distribution, may be described as a novel fungus specific to Fagus. Its evolutionary nuSSU–complete ITS–partial nuLSU rDNA phylogeny indicates its likely emergence by asexual fusion or introgressive hybridization between diverged B. nummularia and B. anceps species. The name Biscogniauxia destructiva is proposed for the novel fungus, as it is aggressive and highly destructive BTC disease.
