Entoloma virescens (Sacc.) E. Horak ex Courtec., 1986 (Agaricales: Entolomataceae): the first record for the Caatinga biome, Ceará, Brazil

Abstract

Entoloma virescens, a rare mushroom with deep blue coloring and cuboid spores, is recorded for the first time in the Caatinga biome in Brazil. The relevance of this finding is that such area is characterized by an atypical environment for the occurrence of species normally considered from temperate and humid tropical regions. The record is fully described and illustrated. Also, a brief analysis of taxonomical features and geographical distribution of the taxon are included.

Entoloma mengsongense sp. nov. (Entolomataceae, Agaricales),a remarkable blue mushroom from Yunnan Province, China

“…Although E. mengsongense is phylogenetically closely related to E. virescens and E. hochstetteri, it is morphologically distinct. Entoloma virescens differs from E. mengsongense in having a wavy margin to the pileus, larger (10.5-12.5 × 10.5-12 µm) cuboid basidiospores, 30-52 × 10-17 µm size basidia, 30-62 × 12-16 µm size cylindro-clavate cheilocystidia (Alves and do Nascimento, 2012). Entoloma hochstetteri differs from our new species in having an indigo-blue pileus, 9.9-13.2 × 11.8-13.2 µm size basidiospores, 35-44 × 9-13 µm size basidia; and 40-60 × 8-14 µm, fusoid cheilocystidia.…”
