A New Genus of the Actinomycetales—Intrasporangium gen.nov.

SUMMARY: A new species and genus of the Actinomycetales is described, for which the name Intrasporangium calvum is proposed. The organism is a typical actinomycete, producing branching mycelium 0.4-1.2 μ in diam. which has a definite tendency to fragment. It is characteristic for the organism to produce sporangia intercalary in the mycelial hyphae. The sporangiospores are non-motile. This new genus is proposed to be a member of the family Actinoplanaceae.
