Kerniomyces
Kerniomyces Toro, J. Agric. Univ. Puerto Rico 22: 452 (1939).
Index Fungorum number: IF 2564; Facesoffungi number: FoF 07046, 1 morphological species (Species Fungorum 2022), no molecular data available.
Saprobic on host. Sexual morph: Colonies amphigenous, widely separate, 2.3–5 mm in diameter grayish black, not shiny, smooth, evident superficial mycelium absent, thyriothecia lineal, longitudinally dehiscent, lembosioid, rarely y-shaped by confluency, margin entire, composed of olivaceous brown, septate cells which form a close network, aperture 40–80 μm wide; exposing the contents which are hyaline when fresh, brownish when dry. Asci numerous, ellipsoid, tunicate above, short pedicellate, 8-spored, somewhat bent, separated by a thick-gelatinous, paraphysoid tissue which is hyaline-olivaceous at first brownish with age. Ascospores filiform, distributed in two rows or somewhat inordinate, thin-walled, 3–4 septate, not constricted, hyaline. Asexual morph: Unknown (adapted from Toro 1939).
Type species: Kerniomyces costi Toro
Notes: Kerniomyces was introduced by Toro (1939) with K. costi as type species. Kerniomyces lacks taxonomic description and the holotype material is lost. Petrak (1950) treated Kerniomyces in Myriangiales but Eriksson and Hawksworth (1985) transferred Kerniomyces in Schizothyriaceae. Eriksson and Hawksworth (1987), Kirk et al. (2001, 2008), Lumbsch and Huhndorf (2010), Hyde et al. (2013), Wijayawardene et al. (2014) accepted the treatment of Petrak (1950) and placed Kerniomyces in Schizothyriaceae. Phookamsak et al. (2016) transferred Kerniomyces to Schizothyriaceae, genera incertae sedis due to lack of information. The taxonomic placement of Kerniomyces is doubtful and the fungus needs to be re-collected and a description provided.
