A second record of Entoloma azureoviride (Agaricales, Basidiomycota) from Brazilian Amazon

Abstract

ABSTRACT A new material collected and the holotype of Entoloma azureoviride were studied. The analysis of these specimens showed some discrepancies with the protologue which are discussed here. The diagnostic characters of this species are the following: fibrillose pileus, blue lamellae, cuboid spores, and abundant oleiferous hyphae in the lamellae trama. It was also observed a peculiar pseudoparenchymatous pileus trama consisting of inflated elements up to 25 µm in diam., that become more elongated towards the hymenium. A comparison of E. azureoviride with other species with blue tints in the subgenus Inocephalus and a discussion about its morphological peculiarity are provided.
