Pictorial Atlas of Soil and Seed Fungi: Morphologies of Cultured Fungi and Key to Species, Third Edition describes and illustrates more than 515 fungal species, including:

• 49 oomycetous species belonging to seven genera
• 42 zygomycetous species belonging to 12 genera
• 52 ascomycetous species belonging to 28 genera
• 42 basidiomycetous species belonging to 27 genera
• 319 anamorphic (deuteromycetous or mitosporic) species belonging to 145 genera

Dr. Watanabe describes all fungi alphabetically under the orders of Oomycota, Zygomycota, Ascomycota, Basidiomycota, and Anamorphic (Deuteromycetous) fungi. For each genus, he includes type species, references, morphology, and materials. Morphologies of cultured fungi are briefly described and illustrated together with the description of the isolation sources and methods.

The book illustrates all fungi alongside morphologies and colonies of their fresh agar cultures or dried specimens, providing ready access to morphologically similar fungi for quick comparison.

Most of the fungi are isolated from soil, plant roots, and seeds, and the rest are from wood-inhabiting fruiting bodies, their spores, or the spore-like structures associated with them. They are mostly collected in Japan, but some are from the Dominican Republic, Paraguay, Switzerland, and Taiwan, R.O.C.
