Resumen

An emendation of the generic description of Scleroderma is proposed to consider the membranaceous veil
like, or granulose patches, both on the base of the globose basidiome or on the upper part of the stipe, formed by
the growth of the basidiome, which breaks the exoperidium. Veligaster previously segregated by this character, is a
synonym. Guzmán’s classification of the genus in 3 sections is followed, however due to the change of the type of
the genus for S. verrucosum, Sect. Aculeatispora is now a synonym of Sect. Scleroderma, and S. citrinum that was in
Sect. Scleroderma is now in a new section named Reticulatae. A review of the 21 Mexican species of Scleroderma
is presented, 14 of these are accepted. The most common species in the country is S. nitidum in the tropical and
subtropical forests. New localities from Mexico and foreign countries are discussed in S. bermudense, S. bovista, S.
citrinum, S. hypogaeum, S. michiganense, S. polyrhizum, and S. pseudostipitatum. On the other hand, it is discussed that
S. sinnamariense seems absent in Mexico, because it was confused with S. bermudense.
