Description:—The morphological description of this species appears in Karstedt & Capelari (2013).

Habitat:—Solitary or gregarious, in soil, in the Atlantic Forest biome.

Distribution:—Originally described from the state of São Paulo (Karstedt & Capelari 2013) and now reported from the state of Santa Catarina.

Additional material examined:— BRAZIL. São Paulo: Santo André, Paranapiacaba Biological Reserve, Trail 15, 7 November 2007, F. Karstedt FK0940 (Holotype, SP; isotype, K); 16 December 2009, M. Capelari & L.A. Silva Ramos 4459 (SP); Santa Catarina: Praia Grande, Morro da Moça (around the Serra Geral National Park), 21 January 2011, F. Karstedt FK1770 (SP) .

Comments:— Entoloma cervinum is phylogenetically related to E. aff. luteum (He et al. 2013) and E. mocamboense sp. nov. (Fig. 3), which are characterized by a nolanioid basidiome with a convex-umbonate translucent-striate pileus and a delicate, whitish stipe. Entoloma cervinum is characterized by a white stipe, a pale yellowish brown, between dark yellow and brown, or brown pileus, which is darker at the centre (Fig. 38a–b). The pileipellis is a cutis and in places trichodermal; the clusters of erect hyphae forming the macroscopic punctations present on the pileus surface. Entoloma mocamboense differs by its more delicate, thin pileus (Fig. 38.f), and a pileipellis as a simple cutis.
