Abstract
SUMMARY Three filamentous micro-organisms are described. They are typical Actinomyce- tales forming branching hyphae, 1.5 p or less in diameter, which are differentiated into a substrate (primary) mycelium and an aerial (secondary) mycelium. They have an unusual mode of sporulation since they form chains of conidia both on the substrate and on the aerial mycelium. A new genus, Micropolyspora, is proposed. The type species is M. brevicatena. The new genus is part of the family Actino- mycetaceae. The abolition of the family Streptomycetaceae is proposed.
