Abstract

Neopaxillus echinospermus is a common but poorly understood agaric species from South America (Argentina, Bolivia, Brazil and Paraguay). In this paper, we discuss conflicting morphological features reported in the literature and expand the distribution of the species to Seasonal Deciduous and Semideciduous Forests from Rio Grande do Sul and Paraná states, respectively, in Southern Brazil. Hyphal structure of the pileipellis, presence of cheilocystidia and caulocystidia, presence of clamp connections and oleiferous (thrombopleurous) hyphae, and the basidiospore morphology under scanning electron microscopy are illustrated and discussed in detail.
