Abstract
In Mexico, there are 55 wild species of Agaricus representing approximately 10 % of the world’s diversity of the genus. 22 species of these wild mushrooms are traditionally consumed. The lack of keys for the identification of Mexican species, the difficulties in recognizing distinctive morphological characters and the need for comprehensive studies in some sections of the genus, makes it difficult to distinguish species complexes. The edible species known locally as “ojo de venado” was previously identified as A. sylvaticus in Mexico. Our phylogenetic analyses revealed that this ethnotaxon, which is sold in the markets of Xalapa (Veracruz, Mexico), includes at least two species of A. sect. Subrutilescentes. One of them, Agaricus cervinoculus, is described as a new species. A full description, photographs and comparisons to other similar species are provided. This new species constitutes a well-supported monophyletic clade, sister to the “A. subrutilescens” group.
