Questions
A subcutаneоus nоdule develоps in а florist аnd is submitted for microbiology cultures. Fungal cultures incubated at 30ºC grow a small, white yeast-like colony which later becomes wrinkled and leathery and brown in color. On microscopic examination, thin septate hyphae with slender tapering conidiophores are observed, the apex of which bears small, pear-shaped conidia on delicate denticles forming a rose-like cluster. What is the likely identification?
