Metacapnodiaceae S. Hughes & Corlett (Hughes 1972

Metacapnodiaceae S. Hughes & Corlett (Hughes 1972) Classification. Order incertae sedis, Chaetothyriomycetidae, Eurotiomycetes. Morphological characters. Dark, moniliform hyphae form a black or dark brown subiculum, usually on plant surfaces coated with insect honeydew. Hyphae taper smoothly towards their tips (e. g., Figs 1 B, 4 A). Cells are typically wider than long. Asexual states various but most species have a capnophialophora asexual form with dark-colored phialides bearing prominent collarettes. Metacapnodiaceae comprises two genera: Metacapnodium Speg. (Spegazzini 1918); IF 3137 Ophiocapnocoma Bat. & Cif. 1963 (Batista and Ciferri 1963); IF 3592. Notes. The number of septa per ascospore separates Ophiocapnocoma, with more than 13 transverse septa, from Metacapnodium with fewer than 13 septa (Sivanesan 1984). However, no sequence data are available for Ophiocapnocoma, and we are unable to test whether ascospore septation is diagnostic for clades.
