Epiphytic on the surface of living leaves. Sexual morph: Undetermined. Asexual morph: Mycelium composed of branched, septate, greenish-brown hyphae on PDA. Conidiophores lacking, reduced to conidiogenous cell. Conidiogenous cells phialidic, intercalary, hyaline, with the inconspicuous collarette, with aggregated loci. Conidia subcylindrical to cylindrical, hyaline to sub-hyaline, 4–6-septate, constricted at the septa, curved, smooth-walled, guttulate, each segment divided by a secondary median septum (Crous et al. 2009, Réblová et al. 2013).
Notes – Réblová et al. (2013) introduced Aphanophora Réblová & Unter. to accommodate the type species Aphanophora eugeniae (Crous & Alfenas) Réblová & Unter. (Basionym: Cyphellophora eugeniae Crous & Alfenas) with evidence from phylogenetic analysis and the morphological distinction between Aphanophora and Cyphellophora. Species of Aphanophora produce intercalary phialides and the cylindrical-elongate conidia are divided into septate segments. Aphanophora resembles Camptophora and they cluster together with high support (Réblová et al. 2013). However, the collarettes in Aphanophora are inconspicuous, and the multiple conidiogenous loci become swollen, while C. hylomeconis (Crous, de Hoog & H.D. Shin) Réblová & Unter. produces conspicuous phialides and has a single conidiogenous locus. In our phylogenetic analysis based on combined LSU and ITS sequence data, A. eugeniae clustered with Fumagopsis stellae Crous & A.J. Carnegie and formed a sister group with C. hylomeconis However, F. stellae is distinctly based on its star-shaped conidia. Currently, no sexual morphs are linked to Aphanophora. Thus, the hyphomycetous genus Aphanophora is accepted in Chaetothyriaceae primarily based on phylogenetic analysis.
