Of the following organisms, which causes chromoblastomycosis?

A patient with thickened and discolored nails was diagnosed with onychomycosis.  You received clippings of the nail in the laboratory for culture.  Microscopic analysis of the mold colony growth revealed many globose microconidia and thin walled, smooth, cigar shaped macroconidia that had four to five cells separated by parallel cross-walls.  You will identify this organism as

Fungi that reproduce asexually are termed

A bone marrow sample obtained from an immunocompromised patient revealed small intracellular cells using a Wright’s stain preparation.  Growth on Sabouraud dextrose agar plates of a mold phase at 25°C and a yeast phase at 37°C designates the organism as dimorphic.  The mold phase produced thick, spherical tuberculated macroconidia.  What is the most likely identification?

A yeast identification system gave a biotype number for an unknown isolate that did not differentiate between Candida tropicalis and Candida parapsilosis.  This isolate could be identified as C. parapsilosis in a cornmeal agar preparation if it produced which of the following?

A culture of skin scrapings reveals a fungus that produces club-shaped (spatulate) macroconidia and no microconidia.  Which of the following organisms is most likely?

A dark pigment produced by colonies growing on birdseed agar is due to

A patient can be diagnosed with chromoblastomycosis when we find this in the laboratory.

A common presentation of infection with this organism is “fungus ball”.

Microscopic examination of a gray-white mold described as a “lid lifter” revealed erect sporangiophores immediately adjacent to the rhizoids.  This genus is probably
