Sori forming irregular black spots in leaves and stems, not breaking down. Hyphae with clamp connections, exclusively intercellular, septal pore simple with membrane caps, haustoria absent but specialized interaction apparatus present with non-homogenous contents. Teliospores embedded in host tissue, variable in shape and size, often polyhedral due to compression, dark brown, thick walled, smooth or tuberculate. Basidia formed directly from germinating teliospores, aseptate (exobasidium type), hypha like, thin walled, usually with a cluster of 4 apical (top of apex), sterigmata. Basidiospores discharged actively, fusiform to cylindrical, 2 celled, hyaline, germinating in turn to produce narrow cylindrical yeast-like cells.

Distribution - south and south-east Asia.

Biotrophic (living in symbiosis) in leaves and stems of (fern-like) Selaginella species.

Ecology
--use as guide -- They are parasitic on plants, attaching to leaves and stems of monocotyledons. Doassansia sagittaria and Doassansia deformans can be found on plants of Sagittaria lancifolia, Doassansia alismatis can be found on various species of Alisma and both Doassansia occulta and Doassansia martianoffiana can be found on various species of Potamogeton plants. Also, Acornus calamus is a host to Nannfeldtiomyces sparganii and the leaves of Sparganium americanum are a host to Nannfeldtiomyces anomalus. Narasimhania also affects Alisma plants.

They can affect water plants as well as land based plants.
