A culture from a chronic interdigital lesion of the foot grew a mold that is yellow to buff on the surface with a red-brown reverse, rare pencil-shaped macroconidia, and numerous microconidia in grapelike clusters with some spiraling hyphae also observed.  The organism is also positive for both urease and in-vitro hair perforation.  This organism is most likely:

An immunocompromised patient from the mid-west became severely anemic.  A bone marrow sample showed macrophages with numerous small oval yeast cells inside.  Lung tissue biopsy also showed alveolar macrophages with intracellular budding yeast.  Similar organisms were seen in biopsy samples of the spleen and liver.  The fungal culture demonstrated large macroconidia with finger-like projections and some small, oval microconidia.  The most likely organism involved is:

A patient from eastern Kentucky had a recurring cough which progressively worsened over time with concurrent weight loss.  Sputum samples showed large, round yeast with thick connection budding forms on a direct mount.  The most likely cause of the pneumonia is:
