Pseudodidymaria
Pseudodidymaria U. Braun, Cryptog. bot. 4(1): 110 (1993).
Index Fungorum number: IF 11485; Facesoffungi number: FoF 08644, 3 morphological species (Species Fungorum 2022), no molecular data available.
Associated with leaf spot. Mycelium consisting of hyaline or faintly pigmented, septate, thin-walled and branched hyphae, forming well developed stromata. Sexual morph: Unknown. Asexual morph: Conidiomata basistromatic and sporodochial. Conidiophores arranged in palisade like fascicles, subcylindrical, subclavate, straight to flexuous, sinuous, rarely septate, hyaline to faintly pigmented, thin-walled, smooth, sometimes reduced to conidiogenous cells. Conidiogenous cells integrated, terminal, polyblastic, sympodial, conidiogenous loci bulging, unthickened or with a thickened rim, not darkened but refractive. Conidia formed singly, ellipsoid obovoid, subclavate, aseptate to 2-septate, base rounded to broadly truncate, hyaline to faintly pigmented, thin-walled, smooth to verruculose, hilum unthickened, not darkened but refractive, conidial secession schizolytic (adapted from Braun 1998; Videira et al. 2016).
Type species: Pseudodidymaria wyethiae (Ellis & Everh.) U. Braun
Notes: Pseudodidymaria is characterised by basistromatic and sporodochial conidiomata, subcylindrical, subclavate conidiophores, with integrated, terminal, polyblastic conidiogenous cells and ellipsoid, obovoid,or subclavate conidia. The placement of Pseudodidymaria in Mycosphaerellaceae is doubtful. Fresh collections with DNA sequence data are needed to confirm the taxonomic placement of Pseudodidymaria.
