Abstract

The large morphological variability of Tricholomopsis rutilans sensu lato is assessed through a detailed morphological study and analyses of the ITS-LSU regions of the nrDNA. Our Maximum Likelihood and Bayesian analyses coding indel information, show that T. rutilans is actually a species complex. Specimens of T. rutilans s.l. form 4 lineages, all of them characterized by having red-purple tones on the stipe, broadly ellipsoid to subglobose spores and narrow pleurocystidia 4-7 µm broad. One of those lineages is described as the new species T. pteridicola, collected in the Western Pyrenees, featured by its slender fruitbodies, pale yellowish cream lamellae and association with Pteridium aquilinum. We identify the lineage that comprises most specimens as T. rutilans s. str. and we propose a lectotype accompanied by an epitype to stabilize the use of the name. Tricholomopsis rutilans var. splendidissima is reduced to synonymy with T. rutilans based on morphological examination and the ITS sequence of the type specimen. The other two lineages, referred to as T. aff. rutilans 1 and T. aff. rutilans 2, are at present morphologically not distinguishable with certainty from T. rutilans, and we conclude that further morphological and molecular studies are needed in order to formally describe them.
