The germ tubes will grow to form the hyphae and fungal mycelia. It has septate hyphae with a woolly colony texture and white mycelia. When environmental conditions are suitable, the chlamydospores germinate, producing mycelia (or hyphae) and sporangia. They have aerial mycelia and spherical, motile spores. Mature mycelia contain some psilocybin, while young mycelia (recently germinated from spores) lack appreciable amounts. "Diplocarpon rosae" over seasons as mycelia, ascospores, and conidia in infected leaves and canes. In this species, hyphal coiling occurs at the contact site of sexually compatible mycelia. When the spores germinate, they develop into new mycelia. The basidiospores are ballistically discharged and start new haploid mycelia called monokaryons. Conversely, the haploid mycelia are called monokaryons. The fungal body is not bioluminescent but its mycelia are luminous when in active growth. Extensions called gametangia are formed from each of the compatible haploid mycelia. Rapidly growing mycelia helps speed up the growth of this fungus. Before leaving the nest, queens stuff some of the fungus' mycelia in her cibarium. These are myco-heterotrophs and feed parasitically off of one or more of the local mycelia.
