Unknown 67 = Rhinocladiella atrovirens
|A cattle worker from tropical Queensland presented with chronic verrucous cutaneous lesions the hand. The culture described below was isolated.|
Chronic verrucous chromoblastomycosis of the hand. Note tissue hyperplasia forming a white verrucoid cutaneous lesion. In Australia, chromoblastomycosis occurs mostly on the hands and arms of timber and cattle workers in humid tropical forests.
Cultures of Rhinocladiella atrovirens are restricted, velvety or lanose, olivaceous, often slightly mucoid at the centre; reverse dark olivaceous green to blackish.
Budding cells, if present, are hyaline, thin-walled, broadly ellipsoidal, 3.0-4.3 x 1.7-2.5 µm. Germinating cells are inflated, spherical to subspherical, 4.5-6.0 µm.
Conidiophores are short, brown, thick-walled. Conidiogenous cells are cylindrical, intercalary or free, 9-19 x 1.6-2.2 µm; denticulate rachis up to 15 µm long, with crowded, flat or butt-shaped, unpigmented conidial denticles. Conidia are hyaline, thin- and smooth-walled, short-cylindrical, with truncate basal scars, 3.7-5.5 x 1.2-1.8 µm. RG-1 organism.
