4. Dimorphic fungi may exhibit two different growth forms. Outside the body they grow as a mold, producing hyphae and asexual reproductive spores, but in the body they grow in a yeast-like form. 5. The appearance of a mold and the type of spores it produces is useful in its identification.. Dimorphic fungi. Dimorphic fungi may exhibit two different growth forms. Outside the body they grow as a mold, producing hyphae and asexual reproductive spores, but in the body they grow in a non-mycelial yeast form.
Generally, infection of the host with dimorphic fungi typically occurs following disruption of the mycelial cells residing in soil and subsequent inhalation of airborne microconidia, which transform into a parasitic yeast form in the pulmonary alveolar epithelium.n the soil, both Coccidioides species produce hyphae and mitospores, and both are specifically adapted to live in mammals, including humans. When mitospores are inhaled, they enlarge to make spherules, which divide internally to make endospores.
