Neocelosporium
Neocelosporium Crous, in Crous et al., Persoonia 41: 307 (2018).
Index Fungorum number: IF 828206; Facesoffungi number: FoF 07663, 2 morphological species (Species Fungorum 2021), 1 species with molecular data.
Saprobic or pathogenic on host substrate. Sexual morph: Unknown. Asexual morph: Mycelium spreading, enclosed in mucus, consisting of medium to dark brown, verruculose, hyphae; cells become constricted at septa, swollen, disarticulating, forming conidial propagules, 0–1-septate, ellipsoid. Primary conidia brown, thick-walled, giving rise to secondary conidia via microcyclic conidiation, ellipsoid, hyaline, smooth-walled, aseptate, apex obtuse, base truncate, forming on primary conidia or hyphal cells, becoming brown and thick-walled and swollen with age (adapted from Crous et al. 2018).
Type species: Neocelosporium eucalypti Crous
Notes: Neocelosporium differs from Celosporium in having hyaline conidia that mainly arise on the surface of hyphae while Celosporium is characterised by dematiaceous hyphae forming clumps with numerous hyaline to brown endoconidia. Neocelosporium is a monotypic genus accommodated in its own family Neocelosporiaceae. Molecular markers available for Neocelosporium are LSU and ITS.
