[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.

They have sori that develops on leaves, petioles and stems of plants, it is visible as pale green, yellowish or brownish lesions with spore balls as very small brown dots.

The teliospores are globose or irregularly faceted, hyaline or yellowish, smooth, thin walled, germinating to form a short hypha-like promycelium from which a cluster of basidiospores are produced towards an apex.
