Substrate and aerial mycelia are formed on agar media. Substrate hyphae (0.5–1.0 µm in diameter) are nonfragmenting, branched, and septate. Aerial hyphae (1.0 µm in diameter) are sparsely branched and septate. Gram-stain-positive and non-acid-fast. Cylindrical to clavate sporangia (1.0–1.2 µm × 6.0–8.0 µm), each containing a longitudinal pair of spores, are developed singly or in bundles on short ramifications of the aerial hyphae. The spores (zoospores) are oblong and cylindrical with rounded ends, and are motile by means of peritrichous flagella. Colonies developed on agar media are flat or occasionally elevated, the substrate mycelium either without distinctive color or rose colored. The aerial mycelium, which is formed only on certain agar media, is white or with a light rose tinge. Strains grow well under aerobic conditions. Chemoorganotrophic and mesophilic, growing well at 28–40°C and pH 6.0–9.0. Cell walls contain meso-diaminopimelic acid and whole-cell hydrolysates contain madurose as the diagnostic sugar. Contains diphosphatidylglycerol, phosphatidylethanolamine, hydroxylated phosphatidylethanolamine, and ninhydrin and sugar positive phospholipids as predominant phospholipids. Major menaquinones are MK-9(H₄), MK-9(H₂), and MK-9(H₀). Major types of fatty acids are C₁₇ 10-methyl and C₁₆iso-branched fatty acids.
