Holotype.

INDIA, Gurdaspur: Jaggatpur, Aug. 1938, S. Ahmad 258 (BPI).

Tulostoma subsquamosum is characterized by a hyphal exoperidium with scattered sphaerocyst-like cells. The spores are verrucose-echinate with a tendency to form a subreticulum (Figure 16e). It seems to be one of the more common species in the sand steppe vegetation of Central Hungary, from where it was traditionally recorded as T. squamosum (cfr. Hollós 1904, Rimóczi et al. 2011). In the molecular analyses it comes out as a sister species to T. squamosum (Figure 1c).

Habitat and distribution.

Occurs in dry grasslands on sandy-clayish soil. It has a wide distribution in Asia (India, Pakistan), N and S America and Europe (Hungary, Slovakia, Spain).
