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.

全北极地区的冥王星进化支：现有名称的评估和七个新物种的描述。

Pluteus leoninus是一种常见的报道物种，其特征是黄色的菌毛，茎柄呈黄色，胸膜囊体具有数字状的赘生物，以及由长梭状元素组成的菌毛。在北半球的温带和北方地区，人们已经描述了几个与狮子草有关的物种，以前的系统发育研究表明，在狮子草周围可以识别出不止一个物种，但不清楚有多少种，或者哪些名称是正确的。我们研究了/leoninus支系的141个全北极标本和该支系现有的物种类型标本。考虑到我们数据集中的形态、分子（ITS, tef1）、生态和地理差异，我们识别出12种全北极物种，6种在欧亚大陆（P. favrei， P. leoninus， P. roseipes， P. ochraceoleoninus， P. nov. ussuriensis, sp. nov. variabilicolor）， 6种在北美（P. aureus, sp. nov. croceus, sp. nov. flavofuligineus， P. hesperius, sp. nov. insularis, sp. nov. pumae, sp. nov）。本文简要讨论了辛格在马蹄莲属中所包括的热带物种：原产于斯里兰卡的chrysaegis已被证实出现在北美（佛罗里达、波多黎各）；我们提供了第一个现代描述和P. conizatus的分子数据，最初描述来自斯里兰卡，被证实是Pluteus节的一部分。Hispidoderma，但不属于/leoninus分支。

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.
