Basidiomycetes with branched, water-borne conidia

A number of water-borne fungi with branched conidia have been shown to be basidiomycetes. These fungi resemble aquatic hyphomyectes in their habitat, conidial morphology and ontogeny. Their conidia are typically tetraradiate or elaborately branched. Ingoldiella hamata and Taeniospora gracilis, which produce clamped, tetraradiate conidia, are anamorphs connected to the teleomorphs Sistotrema hamalum and Leptosporomyces galzinii, respectively. Both teleomorphs are members of the Corticiaceae. Dendrosporomyces prolifer and D. splendens, which produce non-clamped conidia resembling the aquatic hyphomycete Dendrospora, have binucleate conidia and typical dolipore septa are present. Other water-borne fungi with basidiomycete affinities include Ingoldiella fibulata and Tricladiomyces malaysianum.
