Dipodascus -mycelium consists of irregular cells and bears long slender asci which taper toward the apex. The ascospores are small, one-celled, and hyaline. Mount a small amount of material from a colony of Dipodascus sp. Note the large number of ascospores in each ascus. The mycelium is composed of well-developed hyphae.
Asexual reproduction is through the production of arthrospores.
Geotrichum -filamentous fungus and a pathogen on fruits. Its teleomorphic stage, Endomycetales geotrichum , occurs when mycelium of opposite mating type come together and an ascus forms in between the two hyphae. Make a mount of Geotrichum candidum growing in culture and look for arthrospores. This family represents the ascomycetous yeasts. Mycelium is scanty or lacking and the asci can contain 1-8 ascospores.
