Secotioid basidiomycetes with well-developed stalks. All with smooth, brown spores with a germ pore. Probably an unnatural, polyphyletic group. At least one New Zealand species, W. erythrocephala, is closely related to Leratiomyces similis, a morphologically similar genus from New Caledonia.

Three species have been reported from New Zealand; all are common and easily distinguished by colour. Saprobes on wood and soil.

Distinguished microscopically from the superficially similar Nivatogastrium (also with 3 New Zealand species, but less common) microscopically.

Saprobe on wood and soil. Secotioid basidiomycetes, distinguished from Nivatogastrium by a lack of chrysocystidia.
