Holotype.

Tulostoma pseudopulchellum is a small and slender species with a macro-morphological resemblance to T. pulchellum . It differs from that species by having significantly smaller basidiomata and irregularly rugulose spores (SEM). It has a distinctly membranous exoperidium and a fibrillose-fimbriate mouth. Moreno et al. (1992b) suggested a close relationship with T. pulchellum but this could not be confirmed in the molecular analyses.

Habitat and distribution.

So far only known from its type locality in dry gypsum slopes at Alcalá de Henares in Central Spain.
