Abstract
Two new species, Marasmius cystidioccultus and Marasmius plenicystidiosus, are here described supposed to be included in Marasmius section Neosessiles. The former species has, as diagnostic characteristic, the moniliod shape of the pleurocystidia hidden in the hymenium layer while the latter one has conspicuous pleurocystidia filled of dense oil-like contents. Full description, taxonomic comments and detailed illustrations are provided for both taxa. This is certainly an important contribution for the section Neosessiles, a less studied group within the genus Marasmius, which is one of the largest genera of Agaricales. Both taxa were collected from Atlantic rain forest, largely rich in biodiversity in Brazil.
