A family that contains a single genus, Completoria, that usually has been placed in Entomophthoraceae (Ben Ze’ev and Kenneth, 1982; Humber, 1984c; Tucker, 1981). Completoria is a rare fungus that was last reported by Atkinson (1895) as an intercellular parasite of fern protallia in a Cornell University green house. Many characteristics of this fungus are unknown because of its rarity. Completoriaceae was described by Humber (1989).
Completoriaceae Humber, 1989 (Mycotaxon 34: 453)
Obligate intercellular parasites of fern gametophytes. Vegetative structures small, irregular hyphal bodies that probably lack cell walls. Conidiophores short, unbranched, arising directly from vegetative cells, without a conidiogenous cell. Conidia unitunicate, more or less globose with a rounded papilla; release by papillar eversion. Resting spores globose (ontogeny and germination unknown), formed in the axis of parental cell.
Type and only genus: Completoria Lodhe.
