First record of Macrocybe titans (Tricholomataceae, Basidiomycota) in Argentina

Abstract

Macrocybe titans is characterized by its basidiomata with a remarkable size, the squamose stipe surface, and the pseudocystidia with refractive content. In this paper, we describe and analyze the macro and microscopic features of Argentinian collections of this species, and provide photographs of its basidiomata and drawings of the most relevant microscopic structures. In addition, we present a map with the American distribution of M. titans, highlighting the first record of this species for the country.
