Index Fungorum number: IF 555799, Facesoffungi number: FoF 14634
Etymology – Named for parvus meaning small, and bulbium meaning bulbilus referring to the small, bulbus chlamydospore-like structures produced in culture.
Asexual morph: Hyphae thin-walled, hyaline, septate, whitish in mass. Producing chlamydospore-like structures, hyaline, globose, thin-walled, singly or rarely in chains, rarely terminally or more commonly intercalarily. Thermophilic, optimal growth at 45°C. Sexual morph unknown.
Diagnosis – Closely related to Mycothermus and Remersonia (Chaetomiaceae), but differing from Mycothermus by the presence of hyaline rather than pigmented chlamydospores and differing from Remersonia by the lack of synnematous conidiogenous cells.
