Mortierella multidivaricata is described and placed in a new subgenus, Gamsiella, of M ortierella. It is distinguished from species of subgenus M ortierella in having repeatedly divaricately branched sporangiophores. Large numbers of sporangiola develop simultaneously on slender, attenuate pedicels arising from the ultimate branches of the sporangiophore. The sporangiole of M. multidivaricata forms two subglobose, finely sculpttued sporangiospores. Mostly terminal, globose, spiny chlamydospores are formed in slender, secondary, intra- or extrahyphal hyphae that arise from living segments of the ageing aerial mycelium. Classification of the Mortierellaceae is summarized briefly. The type and only known strain of M. multidivaricata originated from a rotting stump in Moscow, USSR.
