Lepiota coloratipes, a new species for Lepiota rufipes ss. Auct. europ. non ss. orig.

Abstract

In a recent paper, Lepiota rufipes ss. orig. (a North American taxon) was synonymised with Cystolepiota seminuda. Accordingly, Lepiota coloratipes sp. nov. is here described for the taxon usually referred to as L. rufipes in Europe. On the basis of recent collections from Europe and China, a full description, colour pictures of basidiomata, line drawings of microscopic features and ITS phylogenetic analysis are provided. A unique combination of morphological characters-i.e. hymeniform pileus covering, cheilocystidia of variable shape, fugacious partial veil not forming an annulus, presence of oil droplets in all tissues, and uninucleate spores-corresponds to an isolated position of its sequences in the phylogenetic tree.

Lepiota sanguineofracta (Basidiomycota, Agaricales), a new species with a hymeniform pileus covering from Italy

“…1), Lepiota coloratipes is the most closely related species to L. sanguineofracta. This recently described species (Vizzini et al 2013), only so far known from Europe, China and North America, was established for the taxon usually referred to as L. rufipes in Europe, non-ss. orig.…”

“…Based on the BLASTn results (sequences were selected based on the greatest similarity) and outcomes of recent phylogenetic studies focused on Lepiota with a hymeniform pileus covering (Vellinga 2003(Vellinga , 2010aVizzini et al 2013) sequences were retrieved from GenBank for the comparative phylogenetic analysis. Besides Lepiota species with a hymeniform pileus covering, eight species (indicated by an asterisk in Fig.…”

“…Paralepiotula M. Bon) as a whole, mainly based on different spore shapes (either ellipsoid or spurred) and spore nuclear number (mononucleate vs binucleate). According to recent molecular analyses, the species with a hymeniform pileus covering do not form a monophyletic lineage (Vellinga 2001(Vellinga , 2003(Vellinga , 2010aVizzini et al 2013), even though most of them (with different spore shapes and nuclear number) fall in a clade (named clade 3 in Vellinga 2003) which includes also taxa (L. cystophoroides Joss., L. luteophylla Sundb. and L. scaberula Vellinga) with a hymeniform pileus covering giving rise to loose globose elements (a transition between hymeniderm and epithelium, see Vellinga 1998).…”

Smithiomyces dominicanus (Agaricales: Agaricaceae), a new species from the Dominican Republic

“…A first, preliminary dataset included a total of 357 nrItS sequences, representing the major lineages in the family Agaricaceae. these sequences mainly come from the studies of baroni et al 2014 Sysouphanthong et al (2011Sysouphanthong et al ( , 2012, Vellinga (2001aVellinga ( , 2001bVellinga ( , 2001cVellinga ( , 2003Vellinga ( , 2004Vellinga ( , 2007Vellinga ( , 2010, Vellinga et al (2011) and Vizzini et al (2014aVizzini et al ( , 2014b. Sequences were aligned using MAfft version 7 (Katoh & toh 2008) and the strategy fft-NS-i was selected.…”

Looking for Lepiota psalion Huijser & Vellinga (Agaricales, Agaricaceae)

“…According to recent molecular analyses, the species with a hymeniform pileus covering do not form a monophyletic lineage (Vellinga 2003, 2004, 2010; Vizzini et al 2014a, b; Justo et al 2015; Qasim et al 2015; Hosen et al 2016), even though most of them (with different spore shapes and nuclear number) fall in a clade (named clade 3 by Vellinga 2003) which also includes taxa as L.albogranulosa T. Qasim & A.N. Khalid, L.cystophoroides Joss.…”
