Wingfieldomyces
Wingfieldomyces Y. Marín & Crous, in Marin-Felix et al., Stud. Mycol. 94: 113 (2019).
Index Fungorum number: IF 829671; Facesoffungi number: FoF 08341, 1 morphological species (Species Fungorum 2022), 1 species with molecular data.
Saprobic on host. Sexual morph: Ascomata immersed on host, erumpent in culture, black, globose, with central ostiole; ascomatal wall of 3–4 layers of dark brown cells of textura angularis. Pseudoparaphyses intermingled among asci, hyaline, septate, branched prominently, constricted at septa. Asci bitunicate with apical chamber, subcylindrical, hyaline, smooth, fasciculate, stipitate, 8-spored. Ascospores trito multiseriate, fusoid with subobtusely rounded ends, finely verruculose, red-brown, guttulate, 2-septate, slightly constricted at septa, with central cell somewhat swollen. Asexual morph: Unknown (adapted from Marin-Felix et al. 2019).
Type species: Wingfieldomyces cyperi (Crous & M.J. Wingf.) Y. Marín & Crous
Notes: Wingfieldomyces is characterised by black, globose ascomata, subcylindrical, hyaline, smooth, fasciculate asci and fusoid with subobtusely rounded ends, finely verruculose, red-brown, 2-septate ascospores. Wingfieldomyces cyperi, previously known as Setophoma cyperi, was not congeneric with the type of Setophoma. Wingfieldomyces differs from Setophoma in that the latter is characterised by 2- seriate, 3-septate, hyaline ascospores with the second cell from the apex becoming swollen. Wingfieldomyces is phylogenetically related to Pringsheimia but differs morphologically in that the latter is an asexual morph genus characterised by club-shaped conidia rounded on both sides while Wingfieldomyces is a sexual morph. The DNA barcode to identify Wingfieldomyces at the genus level is LSU and at species level are ITS, RPB2 and BTUB (Marin-Felix et al. 2019). Wingfieldomyces is a distinct and well-supported genus in Phaeosphaeriaceae. Molecular markers available for Wingfieldomyces are ITS, LSU, BTUB, RPB2 and TEF-1.
