Pseudocoronospora Z.F.Yu, M. Qiao & R.F. Castan˜eda, gen. nov.
MycoBank number: MB 840431; Index Fungorum number: IF 840431; Facesoffungi number: FoF 05736;
Etymology: Name refers to the morphological similarity to the genus coronospora.
Asexual morph hyphomycetous. Conidiophores macronematous, mononematous, erect, straight, septate, unbranched, smooth, brown. Conidiogenous cells polyblastic, sympodial extended, integrated, terminal, indeterminate, denticulate. Conidial secession rhexolytic. Conidia solitary, acropleurogenous, obclavate, crowned, with mammiform protuberances arranged near the apex; septate, smooth or verruculose, hyaline, fringed at the base. Sexual state: Unknown.
Type species: Pseudocoronospora hainanense Z.F. Yu, M. Qiao & R.F. Castan˜eda.
Notes: The genus Coronospora was established by Ellis (1971) with C. dendrocalami M.B. Ellis as the type species, in which after the conidiogenous events the cicatrized loci are produced following sympodial extensions of the polyblastic conidiogenous cells disposed in geniculate conidiophores and the conidia are liberated via schizolytic conidial secession (Seifert et al. 2011; Zhang and Zhang 2004; Ellis 1971), but in Pseudocoronospora hainanense the conidiogenous loci are tiny or conspicuous denticles and the conidial basal cells are fringed after the rhexolytic conidial secession. Matsushima (2001) observed the Coronospora morph in the culture of Ascoronospora Matsush., so he thought that Coronospora is the asexual state of Ascoronospora. Then Kirk et al. (2008) and Wijayawardene et al. (2018) accepted the link between two genera.
