Noosia Crous, R.G. Shivas & McTaggart, in Crous, Groenewald, Shivas, Edwards, Seifert, Alfenas, Alfenas, Burgess, Carnegie, Hardy, Hiscock & Hübe, Persoonia 26: 139 (2011)
Index Fungorum number: IF 560172; Facesoffungi number: FoF 06660, 1 morphological species (Species Fungorum 2021), 1 species with molecular data.
Associated with leaf spots. Sexual morph: Unknown. Asexual morph: Mycelium consisting of hyaline, smooth, branched, 2–5 µm diam hyphae, becoming brown and verruculose with age, frequently aggregating in hyphal strands of up to 20. Conidiophores reduced to conidiogenous cells that are solitary, lateral, or integrated, inconspicuous, lateral and terminal, with small, pimple-like pores of up to 0.5 µm diam, giving rise to conidia that can be solitary or in short chains of up to 5. Conidia dimorphic; primary conidia aseptate, initially globose, sub hyaline, smooth, becoming fusoid-ellipsoidal, brown, verruculose, solitary or in short, branched chains; apex obtuse, base truncate with minute, unthickened pore; secondary conidia arising as phragmoconidia from disarticulating hyphal cells that become brown and verruculose (adapted from Crous et al. 2011).
Type species: Noosia banksiae Crous, R.G. Shivas & McTaggart
Notes: Noosia was introduced by Crous et al. (2011) with N. banksiae as type species. Noosia is characterized by solitary conidiophores, dimorphic globose, sub hyaline to fusoid-ellipsoidal, brown verruculose conidia and secondary conidia. Noosia resembles Conioscypha in forming similar strange phialides in vitro, but not in vivo. Noosia also resembles Trichobotrys but lacks setae and supporting cells at maturity. Noosia can be differentiated from these similar genera based on DNA sequence data. Phylogenetically, Noosia is a distinct and well-supported genus in Periconiaceae.
