Absidia corymbifera (able to grow at 37°C) is an opportunistic pathogen causing infections of the lungs, skin, meninges, and kidney (mucormycosis) in immunocompromised people.
Notes On Identification:
Not distinctive on spore trap samples. The genus can be identified on surface sample if the entire sporulating structure is present. Species identification requires mycological examination of sporulating cultures.
Spore Types:
Sporangiospores small, ovoid, ellipsoidal, to globose, mostly hyaline. Common species: A. corymbifera.
