A New Genus of the Actinomycetales: Microellobosporia gen.nov.

Abstract

SUMMARY: Two aerobic mesophilic species of a new genus belonging to the family Actinoplanaceae are described under the name Microellobosporia (M. cinerea type species). The new genus is characterized by the production of small club-shaped sporangia on the aerial mycelium. Similar stuctures are also formed on the substrate mycelium. The non-motile sporangiospores are few in number and arranged in a single straight row inside the sporangium.
