Holotype.

ITALY: in glabrosis prope Tridentinum, 1902, G. Bresadola (K).

This species is closely related to T. squamosum , T. subsquamosum , and the new species T. calcareum . It is distinguished by its dark brown to almost black stipe and a prominent dark peristome contrasting to the pale colours of the surrounding endoperidium in old and weathered specimens. In young basidiomata the endoperidium is more or less orange brown and the stem ± orange brown. The spores are verrucose-echinate and normally lack anastomoses and crests as seen under SEM (Figure 2i). It can be readily distinguished from T. brumale , which often grows in the same locations, by its darker stem and the more coarsely ornamented spores. Photos of the holotype collection at K (habit and spore ornamentation under SEM) were included in Altés et al. (1996).

Habitat and distribution.

Grows in dry sandy grasslands, on sand dunes, sand steppes and rupicolous steppe slopes. According to Wright (1987) it is a typically European species. It is, however, also recorded from Central Asia ( Dörfelt and Täglich 1990). It is widespread in Europe, reaching as far north as southernmost Fennoscandia.
