Abstract
Soil samples from the chief geographic regions and soil types were surveyed by the plate method. Rose bengal-streptomycin agar was most effective for fungi and Thornton''s medium for counts of bacteria, Actinomycetes and fungi. Number of fungi in proportion to bacteria and Actinomycetes was greater in forest soils than in cultivated. Each group varied more with soil type than with geographic regions. Bacteria and Actinomycetes decreased at greater rates with depth of sampling than fungi. All were more abundant in summer than winter. Species of fungi isolated included 22 Phycomycetes, 10 Ascomycetes, 2 Basidiomycetes and 13 Fungi Imperfecti. New species described were Botrytis bifurcata, Chloridium apiculatium, Geotrichum flavo-brunneum, Gliocladium virens, G. flavo-fuscum, Pseudonectria diparietospora, Fusidium terricola, Penicillum aurantiacum, P. rubicundum, and Spicaria carnosa.
