2.2.3 Lobulomycetales (Lobulomycetes, Chytridiomycota)

Lobulomycetales was introduced by Simmons et al. (2009) based on genetic analyses, morphology, and ultrastructural data, with Lobulomyces ( Lobulomycetaceae) and L. angularis as the type genus and species, respectively. Features of the order are a polycentric or monocentric thallus, multiple rhizoidal axes, spherical motile zoospores with or without a flagellar plug, ultrastructural details of the kinestosome, growing on chitin in soil and freshwater/seawater. Two families are assigned to the order Lobulomycetaceae and (Alogomycetaceae). Alogomyces tanneri (Alogomycetaceae) is known from marine habitats; based on environmental DNA samples from the deep ocean (Le Calvez et al. 2009; Yan et al. 2020).
