SOUTH AFRICA, Stoneman, herb. Lloyd 4495 (BPI).

Tulostoma cyclophorum is a morphologically characteristic species, originally described from South Africa, with a tomentose, white to ochraceous endoperidium covered with mycosclereids and a distinctly membranous exoperidium. The mouth is silky fibrillose-fimbriate. Its spores are unique among European Tulostoma lineages, being more or less reticulate (visible under SEM, Figure 2d; asperulate under light microscope).

Habitat and distribution.

Mostly found in semi-shaded localities among grasses and herbs on lawns in city parks on somewhat sandy soil. From Europe currently reported from France, Italy, Hungary, and Spain (Demoulin 1984, Jeppson et al. 2011, Moreno et al. 1990, Sarasini 2005). It appears to have a cosmopolitan world distribution.
