Cladoriella

Cladoriella Crous, Stud. Mycol. 55: 54 (2006).

           Index Fungorum number: IF 500799; Facesoffungi number: FoF 07651, 5 morphological species (Species Fungorum 2022), 4 species with molecular data.

            Pathogenic on leaf surface. Sexual morph: Unknown. Asexual morph: External hyphae coiling on the leaf surface, medium to dark brown, thick-walled, smooth to finely verruculose, branched, septate, with swollen cells giving rise to conidiophores. Hyphopodium-like structures present, simple, intercalary. Conidiophores separate, erect, medium to dark brown, smooth to finely verruculose, thick-walled, subcylindrical, straight, septate. Conidiogenous cells terminal or intercalary, monotretic or polytretic, sympodial, with 1–2 conspicuous loci, thickened, darkened, refractive, with a minute central pore, not protruding. Conidia frequently remaining attached in long acropetal chains, simple or branched, narrowly ellipsoidal to cylindrical or fusoid, 0–1-septate, medium brown, thick-walled, finely verruculose, apical conidium with rounded apex, additional conidia with 1–2 truncate, conspicuous hila; thickened, darkened, refractive, with a minute central pore (adapted from Crous et al. 2006).

 

Type species: Cladoriella eucalypti Crous

 

Notes: Cladoriella resembles Devriesia in having branched, acropetal chains of either non-septate or septate, brown pigmented conidia, but lacks chlamydospores. Cladoriella is phylogenetically a distinct and type genus of Cladoriellaceae. Molecular markers available for Cladoriella include ITS, LSU and SSU.
