The genus Mucor contains several species. See the summary of synonyms for Mucor spp. Smaller sporangia may lack columella. People get mucormycosis by coming in contact with the fungal spores in the environment. 3,6 Mucormycosis can also develop on the skin after the fungus enters the skin through a cut, scrape, burn, or other type of skin trauma. Gill Fungi. Colonies of Mucor grow rapidly at 25-30°C and quickly cover the surface of the agar. Humus‐decomposing fungi accumulate generally more mercury than wood‐decomposing and some mycorrhizal ones (Bargagli and Baldi 1984). D) Rhizopus done clear. Intercalary or terminal arthrospores (oidia) located through or at the end of the hyphae and few chlamydospores may also be produced by some species.
