Saprobic on wood. Sexual morph: Ascomata solitary or scattered, immersed to erumpent, black, turbinate, the apex collapsing when dry, tuberculate, sitting in a subiculum, lacking ostioles, with a central, conical Quellkörper. Peridium composed of brown to hyaline cells of textura angularis to textura prismatica, Munk pores present. Paraphyses absent. Asci 8- to multi-spored, unitunicate, clavate, with long pedicel, apex rounded, without apical ring, evanescent. Ascospores overlapping, hyaline, ellipsoidal cylindrical to broadly fusiform, slightly curved, aseptate, smooth-walled, guttulate. Asexual morph: Undetermined (adapted from Mugambi & Huhndorf 2010).
Notes – Mugambi & Huhndorf (2010) introduced and sequenced four ‘Cryptosphaerella’ species, C. costaricensis, C. cylindriformis, C. elliptica and C. malindensis. These species clustered in a clade and are characterized by lacking ostioles in the ascomata and a Quellkörper, polysporous asci and ellipsoidal to broadly fusiform ascospores (Mugambi & Huhndorf 2010). In this study, they cluster with 100%ML/1.00BY support and are sister to Biciliospora, Scortechiniella and Scortechiniellopsis in Scortechiniaceae. Therefore, we accept these species as members of Pseudocryptosphaerella based on phylogenetic result.
Type species: Pseudocryptosphaerella elliptica (Mugambi & Huhndorf) S.K. Huang & K.D. Hyde, in Huang, Hyde, Maharachchikumbura, McKenzie & Wen, Mycosphere 12(1): 938 (2021).
Other accepted species: Species Fungorum – search Pseudocryptosphaerella.
