Act. nigrificans (Kruger) Wollenweber, Emmend. Yen, 1957. 4. Act. rutgersensis Waksman et Curtis, 1916. 5. Act. inversochromogenes n. sp., sporophores in form of dextrorse spirals with 1to 3 coils. 6. Act. glomerochromogenes n. sp., sporophores in form of short and compactspirals. 7. Act. ansochromogenes n. sp., sporophores in form of hooks or sometime ofloops, soluble pigment reddish brown. 8. Act. ansochromogenes var. pallens n. var., soluble pigment yellowish brown. 9.
