According to the monography of OLÁH (1970), the range of this hallucinogène species comprises Brazil, Bolivia, Central America, Florida, the Philippines and India. On one occasion it was exceptionally found in France. In Hungary it may be only a newly introduced species,far two grassy sites were found between the exhibition pavilions of the Budapest International Fair, where some years ago artifacts from Brazil,India and Viet-Nam had been exhibited. The determination of the fungus was kindly revised by GY.M. OLÁH. Pluteus pearsonii ORTOH (Pig. 3.). It grows on the soil surface or rotten wood in the soil. Cuticle of cap dark grey-blackishgrey-greyishbrown , radially fibrous or torn into scales. The revision of the herbarial material was kindly done by P. D. 0RTON. It occurs regularly in its habitats, it was often collected by myself in parks and grasslands, while KONECSNI regularly observed it in several sandy associations at Csévharaszt ( Fes- tuco-Quercetum roboris danubiale , Convallario-Quercetum roboris danubiale , Quer ceto-UImetum hungaricum , and RobiniaPopulus forests).In the Hortobágy 13 specimen were found on rotten twigs in a QuercusFraxinus forest.
