Didymolepta

Didymolepta Munk, Dansk bot. Ark. 15(no. 2): 110 (1953).

Index Fungorum number: IF 1555; Facesoffungi number: FoF 12193, 3 morphological species (Species Fungorum 2022), no molecular data available.

Saprobic on host. Sexual morph: Ascomata scattered, conic, glabrous, black. Peridium of scleroplectenchymatic cells melanized black. Ostiole absent. Asci bitunicate, subcylindrical, sessile, thick-walled, with eight ascospores. Ascospores 1 -septate, hyaline. Asexual morph: Unknown (adapted from Wettstein 1912).

            Type species: Sphaerella winteriana Sacc.

Notes: According to Art. 41.5 (Melbourne), the name Didymolepta winteriana is invalid. The basionym Sphaerella winteriana has priority and is used. Barr (1987) placed Didymolepta in Leptosphaeriaceae. Didymolepta differs from other members of Leptosphaeriaceae in havinguniseptate ascospores. Molecular data is lacking for Didymolepta. Fresh collections with DNA sequence data are needed to confirm the generic placement of Didymolepta.
