Diagram illustrating the relationship between a mature plant of Herpomyces stylopygae and the integument of Blatta orientalis. Richards and Smith have studied the life history of Herpomyces stylopygae on the oriental cockroach. The plants grow only on living cockroaches, and the infection is disseminated by contact. - Protozoa from the gut of the wood-feeding cockroach
