A Monograph of the Genus Wynnea (Pezizales, Sarcoscyphaceae)

SUMMARY

Previous studies of the genus Wynnea are discussed; the genus and four recognized species are described. All have suboperculate asci and produce auriculate or sparassoid apothecia on multiaxial stalks. Sclerotia are sometimes produced. The four accepted species are: W. americana, from eastern USA, Costa Rica, and Japan; W. macrotis, from Asia; W. gigantea, from Mexico and South America; and W. sparassoides, a new species, from eastern USA. Hypotheses suggesting that Wynnea is a primitive discomycete are advanced.
