Xylariomycetidae, Amphisphaeriales, Pseudomassariaceae, Pseudomassaria

Index Fungorum number: IF 4452; Facesoffungi number: FoF 00843; 24 morphological species (Species Fungorum 2020); 2 species with sequence data.


Saprobic on dead branches attached to trees, seeming as black dots, below small bumps on the bark. Sexual morph: Ascomata black, perithecial, dispersed, solitary or aggregated, immersed, depressed globose, coriaceous, ostiolate, papillate. Ostiolar papilla short, cylindrical, wide at the apex, even with the bark surface, periphysate. Peridium light brown, containing narrow, compacted, thin-walled, cells of textura angularis at the base and thick-walled, light brown to hyaline, isodiametric cells around the ostiole. Paraphyses numerous, hyaline, apically narrow, basally wide. Asci 8-spored, unitunicate, clavate to fusoid, short pedicellate, apically rounded, with a J+ or J– apical ring. Ascospores hyaline, biseriate or partially uniseriate, broadly ellipsoid, oblong or narrowly clavate, apiosporous with a rounded to subconical small lower cell, straight or curved, thick-walled, smooth-walled. Asexual morph: Hyphomycetous. Setae black or dark brown, rigid, straight to flexuous, arising from superficial hyphae, branched at base, subcylindrical, narrowing to thick apex, 3–7-septate, basal cell slightly enlarged. Conidiophores pale brown, setiform to subcylindrical, with radially lobed basal cells, smooth, arising from superficial mycelium, straight to flexuous, 1–10-septate. Conidiogenous cells pale brown, terminal or horizontal, polyblastic, subcylindrical to somewhat clavate, smooth, with 1–4 denticulate loci. Conidia pale brown, lageniform to rhomboid, distal end open, proximal end rostrate, with a subhyaline transverse band at equatorial zone, smooth-walled, guttulate, aseptate (adapted from Maharachchikumbura et al. 2016).


Type species: Pseudomassaria chondrospora (Ces.) Jacz., Bull. Herb. Boissier 2: 663 (1894)




Notes: Pseudomassaria was earlier accepted in Hyponectriaceae and Jaklitsch & Voglmayr (2012) and Senanayake et al. (2015) showed the taxonomic placement of Pseudomassaria in Pseudomassariaceae.
