Neofabraea is a genus of fungi in the family Dermateaceae.[1] The genus contains 12 species.[2]
A morphological monograph of Neofabraea and the related Pezicula and their asexual states[3] stimulated the description of many new species and a multigene phylogeny based on rDNA, RPB2 and TUB2 (beta-tubulin) sequences.[4]
Many of the asexual states were formerly classified in the coelomycete genus Cryptosporiopsis.
Morphology
Sexual states are often associated with cankers on bark, and are leathery black, brown, grey, or reddish apothecia about 1–2 mm diam. that usually lack a stipe, and have 8-spored cylindrical to club-shaped asci, often with an apical ring, and ellipsoidal to curved 1-celled, hyaline ascospores that sometimes germinate and produce conidia from phialides. Asexual states have stromatic coelomycetous conidiomata (which are often sporodochium-like when growing in agar culture) with slimy, cylindrical, ellipsoidal or fusiform 1-celled macroconidia and/or 1-celled cylindrical microconidia.[3]
