Abstract
Tricholomopsis flammula, recently validated, was studied by molecular methods to clarify its taxonomic position. Sequences of T. flammulla form a distinct clade sister to a well-supported clade of T. rutilans sequences, whereas T. decora forms a cluster standing apart from them. T. flammula really is a good species separate from T. rutilans and T. decora, well distinguishable both phenotypically and molecularly. The infraspecific variability revealed by molecular methods is expressed in slight differences among some of the collections studied. The brief characteristics, selected descriptions and illustrations, key diagnostic characters and data on habitats and substrates of T. flammula are given. A discussion on variability of its basidiocarps is added.
