Epiphytic on healthy living leaves. Sexual morph: Undetermined. Asexual morph: Mycelium composed of branched, septate, pale brown hyphae. Conidiophores reduced to conidiogenous cells on hyphae. Conidiogenous cells phialidic, in a flower-like arrangement, intercalary, brown, inconspicuous collarette, forming an outer tent-like collarette surrounding the conidiogenous cells, brown, verruculose. Conidia solitary, fusiform to filiform, hyaline to pale brown, curved, obtuse at the apex, truncate at the base, smooth-walled (Crous et al. 2015b).
Notes – The monotypic genus Cyphellophoriella was introduced to accommodate a cyphellophora-like species and placed in Chaetothyriaceae by Crous et al. (2015b). It is characterized by phialides formed directly on hyphae, petal-like conidiogenous cells and curved conidia (Crous et al. 2015b). The key distinction between Cyphellophoriella and other genera is its flower-like arrangement of conidiogenous cells on a mother cell. Based on the differences in ITS sequence, Cyphellophoriella was clarified as a new genus (Crous et al. 2015b). In our phylogenetic analyses combined LSU and ITS, Cyphellophoriella is not congeneric to Cyphellophora (Cyphellophoraceae), but resides in Chaetothyriaceae with a distinct clade affinity to Ceramothyrium, Chaetothyrium and Nullicamyces. Thus, Cyphellophoriella is accepted as a distinct genus in Chaetothyriaceae.
