Towards a natural classification and backbone tree for Sordariomycetes

et al. 2015

Sordariomycetes is one of the largest classes of Ascomycota and is characterised by perithecial ascomata and inoperculate unitunicate asci. The class includes many important plant pathogens, as well as endophytes, saprobes, epiphytes, and fungicolous, lichenized or lichenicolous taxa. The class includes freshwater, marine and terrestrial taxa and has a worldwide distribution. This paper provides an updated outline of the Sordariomycetes and a backbone tree incorporating asexual and sexual genera in the class. Based on phylogeny and morphology we introduced three subclasses; D i a p o r t h o m y c e t i d a e , L u l w o r t h i o m y c e t i d a e a n dTogniniales. The outline is based on literature to the end of 2014 and the backbone tree published in this paper. Notes for 397 taxa with information, such as new family and genera novelties, novel molecular data published since the Outline of Ascomycota 2009, and new links between sexual and asexual genera and thus synonymies, are provided. The Sordariomycetes now comprises six subclasses, 28 orders, 90 families and 1344 genera. In addition a list of 829 genera with uncertain placement in Sordariomycetes is also provided.

“…Gilmaniella was separated from Humicola and Botryotrichum by its branched conidiophores and the conidia with a conspicuous germ pore ( Barron 1964 ). The conidiophores of Staphylotrichum species are also similar to those of Botryotrichum but do not terminate in setae ( Nonaka et al. 2012 ).…”

The traditional concept of the genus Humicola includes species that produce pigmented, thick-walled and single-celled spores laterally or terminally on hyphae or minimally differentiated conidiophores. More than 50 species have been described in the genus. Species commonly occur in soil, indoor environments, and compost habitats. The taxonomy of Humicola and morphologically similar genera is poorly understood in modern terms. Based on a four-locus phylogeny, the morphological concept of Humicola proved to be polyphyletic. The type of Humicola, H. fuscoatra, belongs to the Chaetomiaceae. In the Chaetomiaceae, species producing humicola-like thick-walled spores are distributed among four lineages: Humicola sensu stricto, Mycothermus, Staphylotrichum, and Trichocladium. In our revised concept of Humicola, asexual and sexually reproducing species both occur. The re-defined Humicola contains 24 species (seven new and thirteen new combinations), which are described and illustrated in this study. The species in this genus produce conidia that are lateral, intercalary or terminal on/in hyphae, and conidiophores are not formed or are minimally developed (micronematous). The ascospores of sexual Humicola species are limoniform to quadrangular in face view and bilaterally flattened with one apical germ pore. Seven species are accepted in Staphylotrichum (four new species, one new combination). Thick-walled conidia of Staphylotrichum species usually arise either from hyphae (micronematous) or from apically branched, seta-like conidiophores (macronematous). The sexual morph represented by Staphylotrichum longicolleum (= Chaetomium longicolleum) produces ascomata with long necks composed of a fused basal part of the terminal hairs, and ascospores that are broad limoniform to nearly globose, bilaterally flattened, with an apical germ pore. The Trichocladium lineage has a high morphological diversity in both asexual and sexual structures. Phylogenetic analysis revealed four subclades in this lineage. However, these subclades are genetically closely related, and no distinctive phenotypic characters are linked to any of them. Fourteen species are accepted in Trichocladium, including one new species, twelve new combinations. The type species of Gilmaniella, G. humicola, belongs to the polyphyletic family Lasiosphaeriaceae (Sordariales), but G. macrospora phylogenetically belongs to Trichocladium. The thermophilic genus Mycothermus and the type species My. thermophilum are validated, and one new Mycothermus species is described. Phylogenetic analyses show that Remersonia, another thermophilic genus, is sister to Mycothermus and two species are known, including one new species. Thermomyces verrucosus produces humicola-like conidia and is transferred to Botryotrichum based on phylogenetic affinities. This study is a first attempt to establish an inclusive modern classification of Humicola and humicola-like genera of the Chaetomiaceae. More research is needed to determine the phylogenetic relationships of “humicola”-like species outsid...

“…To verify that Penicillium strains are unable to conidiate or produce colorless conidia on PDC, microscope slides prepared from PDA and PDC cultures were observed under a light microscope (using Penicillium raphiae FKI-6604). Its penicilli on PDA were very crowded and long (5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20) conidial chains were produced at the apex of the phialides (Figure 3a), whereas its penicilli on PDC were very sparse and only very short (1-3) conidial chains were produced (Figure 3b).…”

This is the first report describing the improved isolation of common filamentous fungi via a method combining cellulose plate and agar plate system. A cellulose plate is a porous plate made of nanofibrous crystaline cellulose. Isolating fungi from soils using these types of media separately resulted in the number of fungal colonies appearing on cellulose plates being lower than that on agar plates. However, the number of actual fungal species isolated using cellulose plates alone was more or less the same as that found using agar plates. Significantly, the diversity of isolates using a combination of the two media was greater than using each media individually. As a result, numerous new or rare fungal species with potential, including previously proposed new species, were isolated successfully in this way. All fungal colonies, including the Penicillium species, that appeared on the cellulose plate penetrated in potato dextrose were either white or yellow. Cultivation on cellulose plates with added copper ion overcomes the change in coloration, the colonies appearing as they do following cultivation on potato dextrose agar.
