[3][4][5] They have parasitic hyphae with clamps, they are also teliosporic (have a thick-walled resting spore) and dimorphic (can be mold or yeasts) as well as not forming ballistocondia (air discharged spores) in the haploid phase.
1997),[8] it had 7 genera (Burrillia, Doassansia, Heterodoassansia, Nannfeldtiomyces, Narasimhania, Pseudodoassansia and Tracya) and 36 species.
