Abstract

Pluteus leoninus is a commonly reported species, characterized by a yellow pileus, yellow colors on the stipe, pleurocystidia provided with digitiform excrescences, and a pileipellis composed of long, fusiform elements. Several species related to P. leoninus have been described from the temperate and boreal areas of the Northern Hemisphere, and previous phylogenetic studies have shown that more than one species can be recognized around P. leoninus, but it was unclear how many, or which names, would be correct for them. We studied 141 holarctic collections in the /leoninus clade and available type collections of species in this group. Taking into account the morphological, molecular (ITS, tef1), ecological, and geographic variation in our data set, we recognize 12 holarctic species, six in Eurasia (P. favrei, P. leoninus, P. roseipes, P. ochraceoleoninus, sp. nov. P. ussuriensis, sp. nov. P. variabilicolor) and six in North America (P. aureus, sp. nov. P. croceus, sp. nov. P. flavofuligineus, P. hesperius, sp. nov. P. insularis, sp. nov. P. pumae, sp. nov.). Tropical species included by Singer in stirps Leoninus are briefly discussed: P. chrysaegis, originally described from Srik Lanka, is confirmed to occur in North America (Florida, Puerto Rico); we provide the first modern description and molecular data for P. conizatus, originally described from Sri Lanka, which is confirmed to be part of Pluteus sect. Hispidoderma but does not belong in the /leoninus clade.

期刊介绍： International in coverage, Mycologia presents recent advances in mycology, emphasizing all aspects of the biology of Fungi and fungus-like organisms, including Lichens, Oomycetes and Slime Molds. The Journal emphasizes subjects including applied biology, biochemistry, cell biology, development, ecology, evolution, genetics, genomics, molecular biology, morphology, new techniques, animal or plant pathology, phylogenetics, physiology, aspects of secondary metabolism, systematics, and ultrastructure. In addition to research articles, reviews and short notes, Mycologia also includes invited papers based on presentations from the Annual Conference of the Mycological Society of America, such as Karling Lectures or Presidential Addresses.
