Which one is not a dimorphic fungi? A . Cryptococcus B . Coccidioides C . Histoplasma D . Blastomyces

The correct answer is B. Coccidioides.<br /><br />Dimorphic fungi are fungi that can exist in two different forms, depending on the environmental conditions. They can grow as yeast cells at body temperature (37°C) and as mold filaments at room temperature (25°C).<br /><br />Cryptococcus, Histoplasma, and Blastomyces are all examples of dimorphic fungi. They can switch between the yeast and mold forms, which allows them to survive in different environments.<br /><br />Coccidioides, on the other hand, is not a dimorphic fungus. It is a genus of fungi that only grows as a mold in the environment and does not have a yeast form. Coccidioides species, such as Coccidioides immitis and Coccidioides posadasii, are the causative agents of coccidioidomycosis, also known as Valley Fever.
