Description:Sporotrichum pruinosum Gilman & Abbott
Colony characteristics. Colonies (MEA) expanding, filling the Petri-dish within 14 days, flat, soft, farinose, dry, white to cream-coloured.
Microscopy. Marginal hyphae hyaline, 3-8 ?m wide, with few septa, later developing more septation, soon with profuse branching at right angles, each branch terminating with a conidium. Conidia with broad base, ellipsoidal to nearly cylinderical, 5-10 x 3-5 ?m, pale brown, with rather thick, smooth walls. Thick-walled, spherical chlamydospores 20-60 ?m in diam, and hyaline arthroconidia frequently present.
Teleomorph. Phanerochaete chrysosporium Burdsall (Basidiomycota, Hymenomycetes, Stereales: Corticiaceae).
Physiology. Optimal growth at 36-40°C, maximum growth temperature 46-49°C.
Pathogenicity. BSL-1. The fungus can be inhaled and then develops a tissue form with giant, thick-walled chlamydospores which are similar to those of Emmonsia parva (p. 636). This has been reproduced in vivo by experimental inoculation (Thirumalachar et al., 1960; Singh et al., 1992). The giant cells can be demonstrated in sputum (Khan et al., 1988).
