Type species – Chlamydosporiella restricta (J.F.H. Beyma) Giraldo López & Crous

Notes – Based on the research of Gams (1971), the study of original material for seven strains and additional specimens and the phylogenetic analysis of the combined alignment of the LSU, ITS, tef1 and rpb2 loci, Giraldo & Crous (2019) introduced Chlamydosporiella to accommodate Acremonium restrictum (≡ Verticillium dahliae f. cerebriforme) (Beyma 1940, Gams 1971). The genus is characterized by bent, unbranched or basitonously branched conidiophores and conidiogenous cells with short collarettes and inconspicuous periclinal thickening at the conidiogenous locus. Conidia are obovoid, widely ellipsoidal, 1-celled, hyaline, thick- and smooth- walled, arranged in slimy heads. Chlamydospores are terminal or intercalary, mostly chains, dark olive green and thick-walled. The sexual morph is undetermined (Giraldo & Crous 2019).
