Neostylopyga rhombifolia: Some development but no mature plants.
Periplaneta americana: Fungus developed prolifically with a density equal to that on original host.
Periplaneta australasiae: Some development but no mature plants.
Periplaneta brunnea: Fungus developed prolifically with a density equal to that on original host.
Herpomyces phyllodromiae Thaxter
Natural host.—"Phyllodromia" sp., Abyssinia (Thaxter, 1905, 1908): On antennae.
Herpomyces platyzosteriae Thaxter
Natural host.—"Eurycotis floridana," Mexico (Thaxter, 1905, 1908): On antennal setae.
Since this cockroach is not found in Mexico (J. A. G. Rehn, personal communication, 1957), E. floridana is undoubtedly not the host for this fungus. W. B. Brown (personal communication, 1957) searched the cockroach collection at the Museum of Comparative Zoology but was unable to find Thaxter's insect for reidentification.
