Remarks (internal):The anamorph differs from Chrysosporium sulfureum by the larger, more globose conidia which become prominently verrucose rather than echinate. Further, C. sulfureum develops semi-synchronously and does not form intercalary conidia. The type ornamentation resembles that of the macroconidia of Histoplasma capsulatum Darling, a species which develops additional microconidia at 24°C and budding cells at 37°C. Renispora flavissima shows little or no mycelial growth at 37°C, but no budding cells.

Description:Chrysosporium anamorph of Renispora flavissima Sigler et al. - Fig. 14.
Teleomorph: Renispora flavissima Sigler et al. - Mycotaxon 10: 133. 1979.
Colonies attaining 30-40 mm diam in 14 days, pale yellow with a buff centre, felty and powdery, 0.5-2 mm high; margin regular, defined, slightly fimbriate; reverse reddish orange. Hyphae hyaline, thin-walled, 1.5-4.5 µm wide, septa sometimes thickened: aerial and submerged hyphae mostly fertile and then more branched. Racquet hyphae rare and showing only slight swellings. Terminal and lateral conidia sessile or on short protrusions or side branches, solitary, rarely subtended by another conidium, subhyaline to pale yellow, initially smooth- and thin-walled, becoming thick-walled and usually verruculose or markedly verrucose with projections reaching a maximum length of 1.5 µm, mostly globose, sometimes pyriform, 1-celled, 5-12 x 4-12 µm, with broad basal scars (1.5-3 µm). Intercalary conidia rare, sometimes alternate, subhyaline to pale yellow, initially smooth- and thin-walled, remaining so or becoming thick-walled and sometimes verruculose, barrel-shaped or urn-shaped, 1-celled, 6-8 x 5-8 µm. Chlamydospores absent.
Growth temperatures: minimum 20°C, optimum 25°C, maximum 30-37°C. Keratinolytic.
