Oedothea Syd., Annls mycol. 28(1/2): 202 (1930).
Index Fungorum number: IF 9139; Facesoffungi number: FoF 08631, 1 morphological species (Species Fungorum 2022), no molecular data available.
Associated with leaf spot. Sexual morph: Unknown. Asexual morph: Stromata on leaf veins, forming small gall-like swellings, subepidermal, erumpent through longitudinal fissures, exposed surface dull black-brown, finely pulverulent to floccose by abundant superficial conidia, intramatrical stromata composed of brown hypertrophic cells of the host tissue, interrupted by small to larger cavities, and sparingly developed filamentous, hyaline hyphae. Conidia in small to larger aggregations, broad ovate, ellipsoid to subglobose, with a single median septum, barely constricted, dark brown but transparent (adapted from Sydow 1930; Videira et al. 2017).
Type species: Oedothea vismiae Syd.
Notes: Oedothea is characterised by stromata on leaf veins, forming small gall-like swellings, broad ovate, ellipsoid to subglobose conidia. The placement of Oedothea in Mycosphaerellaceae is doubtful. Fresh collections with DNA sequence data are needed to confirm the taxonomic placement of the genus.
