Mold (mycelial) form at 25°C (room temperature)

Yeast (or yeast-like) form at 37°C (body temperature)

Can you Enlist other well know facts about dimorphic fungi ??

They often cause systemic infections, typically starting in the lungs after spores are inhaled. Examples include Histoplasma, Blastomyces, and Coccidioides.  
Their ability to switch forms is a key virulence factor, helping them survive and thrive inside the human body.

Dimorphic fungi exist as molds at 25°C and yeasts at 37°C. Examples include Histoplasma, Blastomyces, and Coccidioides. This temperature-dependent shift aids in pathogenicity and immune evasion.

Dimorphic fungi switch between mold and yeast forms. This thermal dimorphism aids infection. Common pathogens: Coccidioides, Histoplasma, Blastomyces, Paracoccidioides.

Dimorphic is a type of fungi that can grow both as yeast and filamentous cells.  
However many of these dimorphic fungi actually can grow in more than these two forms.  
Dimorphic fungi grow as yeasts or spherules in vivo, as well as in vitro at 37°C, but as molds at 25°C.  
e.g.:  
Blastomyces dermatitidis  
Coccidioides immitis  
Histoplasma capsulatum  
Paracoccidioides brasiliensis  
Sporothrix schenckii  
Emergomyces africanus  
Talaromyces marneffei  
Penicillium marneffei  
Candida albicans  
Aspergillus
