Tubeufiales

Tubeufiales Boonmee & K.D. Hyde

Index Fungorum number: IF 585359; Facesoffungi number: FoF 00203

 

Saprobic, common on decorticated or decaying woody and herbaceous substrates, often associated with decaying fungi, less common on leaves, terrestrial and aquatic habitats, widespread in temperate to tropical regions. Sexual morph: Ascomata completely superficial, seated on a subiculum, unilocular, globose-subglobose or clavate to obovate, soft-textured, solitary to gregarious, partially grouped, translucent or not, pale brown, brown to black, minutely papillate and with ostiolar, collapsing cupulate, laterally or not when dry, with radiating mycelium or appendages at base, with or without setose or hairy appendages. Peridium somewhat thickened, mostly composed of cells of textura angularis, thick-walled cells, pale yellow, brown, dark brown to black externally, with thin layers of textura prismatica inwardly, cells narrow, slightly elongate, hyaline, pale brown to brown. Hamathecium comprising numerous filiform, septate, branched, sometimes anastomosing, hyaline pseudoparaphyses, embedded in a gelatinous matrix. Asci 8-spored, bitunicate, fissitunicate, saccate or cylindrical-clavate, sometimes broadly oblong-subclavate, with or without an apically rounded, distinct ocular chamber, with or without a distinct pedicel. Ascospores 2–3-seriate to fasciculate in ascus, elongate, cylindric-subfusiform to narrowly oblong, tapering towards narrow, subacute ends, distinctly multiseptate, hyaline to pale brown, smooth or minutely verrucose. Asexual morph: hyphomycetous; helicosporous, chlamydosporous and phragmosporous. Conidiophores mononematous, macro to micronematous, erect, flexuous, septate, pale brown, brown to dark brown. Conidiogenous cells holoblastic, mono- or polyblastic, integrated or discrete, terminal or intercalary. Conidia usually elongate, filiform to fusiform, curved, helicoid with varying number of coils, septate, sometimes dictyosporous, phragmosporous, hyaline to variously coloured, smooth-walled to verrucose.

Notes: Tubeufiales was established by Boonmee et al. (2014) based on phylogenetic analyses and morphology. Liu et al. (2017) treated Bezerromycetaceae and Wiesneriomycetaceae as families of Tubeufiales on the basis of divergence time estimates. The latest comprehensive revision on Tubeufiales was carried out by Lu et al. (2018), who expanded the circumscription of the type family Tubeufiaceae, accepted 42 genera in this family, and revised the taxonomy of tubeufiaceous species. This revision, in particular, helped to highlight fungi which were misidentified and resolved which morphs are important in classifying species. Tubeufiaceous fungi have the potential to produce bioactive compounds (Ohtsu et al. 2003; Lu et al. 2018; Fan et al. 2019). Fan et al. (2019) tested the antifungal and anticancer effects of 19 tubeufiaceous strains and found that most of them showed obvious bioactivities. We introduce a new morphological record of Tubeufia longiseta. The divergence time for Tubeufiales is estimated as 234 MYA (stem age, Hongsanan et al. 2020).

 

Accepted families: Bezerromycetaceae, Tubeufiaceae, and Wiesneriomycetaceae
