The Doassansiaceae are a family of fungi in the division Basidiomycota and order of Doassansiales. The family contains 11 genera and about 58 species. They have a widespread distribution.Geoffrey Clough Ainsworth {{google books|IFD4_VFRDdUC|Ainsworth & Bisby's Dictionary of the Fungi (2008)|page=219}}P. F. Cannon and P. M. Kirk (editors) {{google books|Lw1VLSH1xnAC|Fungal Families of the World (2007)|page=107}} Doassansiaceae is also known and classified as a smut fungi.Meike Piepenbring, Organization for Flora Neotropica {{google books|yu44AQAAIAAJ|Smut Fungi (Ustilaginomycetes P.P. and Microbotryales, Basidiomycota), 2003|page=193}}K.

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 ballistoconidia (air discharged spores) in the haploid phase.David J. McLaughlin and Joseph W. Spatafora (editors) {{google books|Cyv7CAAAQBAJ|Systematics and Evolution (2013)|page=78}}

When the family was originally created (by R. Bauer and Oberw. 1997),Bauer R, Oberwinkler F, Vánky K. (1997) Ultrastructural markers and systematics in smut fungi and allied taxa. Can J Bot 75:1273–1314 it had 7 genera (Burrillia, Doassansia, Heterodoassansia, Nannfeldtiomyces, Narasimhania, Pseudodoassansia and Tracya) and 36 species. Then Doassinga was added in 1998.{{cite journal |last1=Vánky |first1=K. |last2=Bauer |first2=R. |last3=Begerow |first3=D. |title=Doassinga, a New Genus of Doassansiales |journal=Mycologia |date=December 1998 |volume=90 |issue=6 |pages=964–970 |doi=10.2307/3761268|jstor=3761268 }} Others were added after this date, such as Pseudodermatosorus in 1999.

Description

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 hyphae are intercellular and the spore balls are globose or irregular in shape and composed of a central mass of spores, with a missing central sterile region. They sometimes have sterile cells scattered around and sometimes have a sterile cortex. 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.

Genera

As accepted by the GBIF;{{cite web |title=Doassansiaceae |url=https://www.gbif.org/species/3268 |website=www.gbif.org |access-date=20 August 2022 |language=en}}

Figures in brackets are approx. how many species per genus.

Ecology

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.Donald H. Les {{google books|i7fjDwAAQBAJ|Aquatic Monocotyledons of North America: Ecology, Life History, and Systematics (2020)|page=184}} Narasimhania also affects Alisma plants.

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