Conioscyphaceae Réblová & Seifert, Persoonia 37: 63 (2015)

MycoBank number: MB 813227; Index Fungorum number: IF 813227; Facesoffungi number: FoF 05190; 16 species.

Saprobic on wood and animal skin. Sexual morph: Ascomata perithecial, astromatic, immersed, semi-immersed or superficial, subhyaline to pale orange or pale brown when fresh, almost invisible when dry, papillate or with a cylindrical neck. Peridium coriaceous, two-layered. Ostiole periphysate. Paraphyses filiform, septate, unbranched, longer than the asci. Asci 8-spored, unitunicate, persistent, pedicellate, cylindrical to clavate, sigmoidal, with a tall and prominent J-, refractive apical ring. Ascospores 2–4-seriate, hyaline to subhyaline, ellipsoid to fusiform or fusiform-navicular, transversely septate, not constricted at the septa, lacking any gelatinous sheath or appendages. Asexual morph: Hyphomycetous. Conidiophores micronematous, mononematous, hyaline or pigmented. Conidiogenous cells holoblastic, sympodial, cyathiform or doliiform, surrounded by hyaline, multi-layered, with conspicuous cup-like collarettes. Conidia brown, unicellular, non-septate and varying in shape, thick-walled, smooth, with a pore at the point of attachment to the conidiogenous cells, formed individually and in succession, apices of conidiogenous cells proliferate percurrently, liberated after outer wall of the conidiogenous cell ruptures at the apex (adapted from Réblová & Seifert 2004a, Zelski et al. 2015, Réblová et al. 2016c)

Type genusConioscypha Höhn.

Notes – Conioscyphaceae was introduced by Réblová et al. (2016c) under Conioscyphales and it includes the single genus Conioscypha. Conioscypha lignicola, the generic type, was described by Höhnel (1904) and it was reviewed by Shearer (1973) who introduced a second species C. varia Shearer. The number of species gradually increased and C. tenebrosa is the latest addition to Conioscyphales (Liu et al. 2019b). Most of the species have been isolated as saprobes from submerged substrates (Shearer 1973, Matsushima 1975, 1993, 1996, Crous et al. 2014a, 2018b, Zelski et al. 2015, Chuaseeharonnachai et al. 2017, Hernández-Restrepo et al. 2017, Liu et al. 2019b, Luo et al. 2019) or decaying wood in terrestrial biotopes (Munk 1957, Réblová & Seifert 2004a). Hongsanan et al. (2017) transferred Conioscyphales from Hypocreomycetidae (Réblová et al. 2016c) into the newly introduced subclass Savoryellomycetidae with evidence from well- supported phylogenetic and maximum clade credibility trees with stem age of 268 MYA.
