Mucor amphibiorum

Colonies are greyish-brown, slightly aromatic and do not grow at 37C (maximum temperature for growth is 36OC).   Sporangiophores are hyaline, erect and mostly unbranched, rarely sympodially branched.   Sporangia are dark-brown, up to 75 µm in diameter, and are slightly flattened with a diffluent membrane.   Columellae are subglobose to ellipsoidal or pyriform, up to 60 x 50 µm, with small collarettes. Sporangiospores are smooth-walled, spherical, and 3.5-5.5 µm in diameter.   Zygospores, when formed by compatible mating types, are spherical to slightly compressed, up to 70 x 60 µm in diameter, with stellate projections. Mucor amphibiorum is distinguished by poor ramification of the sporangiophores and by globose sporangiospores. Ethanol and nitrate are not assimilated (Schipper 1978, Scholer et al. 1983, Hoog et al. 2000). RG-2 organism.
