Scleroderma stellatum versus Scleroderma bermudense: the status of Scleroderma echinatum and the first record of Veligaster nitidum from the Virgin Islands.

Abstract

The type of Scleroderma stellatum from Brazil exhibits a sharp echinulate, dark brown peridium, and the type of S. bermudense from Bermuda has a peridium that is loosely woven and fibrillose, whitish to pale brownish. These characters indicate two independent species. This information is contrary to that of Guzmán in 1970, who interpreted S. bermudense to be a synonym of S. stellatum based on the similar spores. Scleroderma echinatum from Borneo and Panama, as recently discussed by Guzmán and Ovrebo, also has an echinulate, dark brown peridium and is a synonym of S. stellatum. All these fungi have a stellate dehiscence. New records of S. bermudense from the Greater Antilles and Mexico's Pacific Coast, and Veligaster nitidum from Virgin Islands also are discussed.
