 No other collections of "Wynnea" were reported for several decades, and in Pier Andrea Saccardo's "Sylloge", the genus was reduced to synonymy with the genus "Midotis".American mycologist Roland Thaxter described a new species in 1905, "W. americana", which was collected in Tennessee.The fruit bodies (technically called apothecia) are thick, firm, tough and become almost leathery after drying.
