Molecular data reveal cryptic speciation within Tricholomopsis rutilans - description of T. pteridicola sp. nov. associated with Pteridium aquilinum

Popis výsledku v původním jazyce

The large morphological variability of Tricholomopsis rutilans sensu lato is assessed through a detailed morphological study and analyses of the ITS-LSU regions. 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 five 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 slender fruitbodies with pileus 7–28 mm in diameter, pale yellowish cream lamellae, and by the association with Pteridium aquilinum. Another lineage characterized by large basidiomata, and sometimes scarce to absent pleurocystidia, is identified as T. rutilans s. str. ITS-LSU sequence divergence between European and North American specimens of T. rutilans is high. To stabilize the use of the name T. rutilans, an epitype from Europe is proposed. Tricholomopsis rutilans var. splendidissima is reduced to synonymy with T. rutilans. The other two lineages, referred to as T. aff. rutilans 1 and T. aff. rutilans 2, are at present morphologically not distinguishable from T. rutilans, but appear to have abundant pleurocystidia. We conclude that further morphological and molecular studies are needed in order to formally describe them.
