The first European records of this traditionally North American species are here confirmed. The species can easily be confused with T. fimbriatum , but is distinguished by the somewhat smaller spores that are more ornamented with a verrucose-spiny ornamentation without ridges (Figure 16a). Study of the macro-micromorphology and sequence data of the type collections of T. punctatum (Figure 17) and T. subfuscum (Figure 18), indicate conspecificity. It is surprising to see that the spore ornamentation of the type of T. subfuscum is very different from the expected one (cfr. description and illustrations by Wright 1987). The presence of distinctive punctate pits on the endoperidium of T. punctatum , as described by Peck (1896), could not be observed in the European specimens. A somewhat pitted appearance of the endoperidium is a common, but inconsistent, feature among species of Tulostoma , and of little taxonomic value. The pits are scars or depressions caused by sand grains adhering to the peridium in early stages of development.
Habitat and distribution.
Originally described from the USA (Kansas). In Europe on sandy soil on exposed, anthropogeneous sites (e.g. church lawns/car parks, abandoned orchards) in SW Slovakia.
