... Singer (1986) emphasized that species of stirps Leoninus could be characterized by a yellowish or reddish coloration of the pileus or stem surface. In recent phylogenetic studies, many species of the leoninus clade have been determined to have a pileus surface of a yellowish color (Justo et al. 2011a, 2011b, Pradeep et al. 2012, Lezzi et al. 2014. However, within both the plautus/longistriatus and the umbrosus/granularis clade, species with diffrent colors have been found which are as yet unnamed and which are in need of identification, and it is suggested that both morphological and molecular work is needed on both clades, with more specimens (Justo et al. 2011a, 2011b, Menolli et al. 2015. ...

Twenty-six species from various sections of the genus Pluteus have been recorded from Turkey until now. In this study, phylogenetic analyses inferred from the nuclear ribosomal internal transcribed spacer (nrITS) were conducted for species delimitation and for comparisons with closely related taxa of Pluteus sect. Hispidoderma in Turkey. Our results show that P. granularis is recorded in Turkey and Europe for the first time, P. granulatus in Turkey for the first time and in Europe for the third time, P. umbrosoides in Turkey for the first time and in the world for the second time, and P. variabilicolor in Turkey for the first time. Also in this study, sequencing data for P. leoninus, P. plautus, P. roseipes, P. semibulbosus and P. umbrosus as well as the above-mentioned new records are presented for the first time from Turkey as a different geographical area. Analyses of the ITS showed that the lowest sequence divergence among in-group taxa was observed between P. semibulbosus and P. aff. semibulbosus 0.010% (SE = 0.004), the next was between P. chrysaegis and P. conizatus var. africanus 0.012% (SE = 0.004). The highest sequence divergence with in-group taxa was found between P. plautus and P. umbrosoides, 0.351% (SE = 0.039). In terms of habitat, Fagus orientalis is recorded as a new host for P. granulatus, P. granularis, P. umbrosoides, and P. umbrosus; Picea orentalis is a new host to P. granularis; Carpinus betulus for P. umbrosus; and the relict endemic Liquidambar orientalis for P. variabilicolor. Finally, this study provides detailed morphological descriptions, macro photographs and microstructure drawings relating to species of Pluteus sect. Hispidoderma from Turkey, which are rare, interesting and noteworthy. An identification key is provided for present species of Pluteus sect. Hispidoderma occurring in the country.

Riassunto Gli autori descrivono le caratteristiche micro-morfologiche di dieci specie appartenenti al genere Pluteus Fr., sezione Hispidoderma. Le descrizioni vengono illustrate con fotografie dei basidiomi in habitat e con quelle delle principali caratteristiche microscopiche. Tutte le specie trattate sono state inserite in un'analisi filogenetica. Pluteus pulcherrimus viene proposto come specie nuova. Abstract The authors describe the micro-morphological characteristics of ten species belonging to the genus Pluteus Fr., section Hispidoderma. The descriptions are accompanied by photographs of the basidiomata in habitat and of the main microscopic features. All the species treated were included in a phylogenetic analysis. Pluteus pulcherrimus is proposed as a new species. Introduzione Il genere Pluteus Fr. (1836: 338), la cui specie tipo è Pluteus cervinus (Schaeff.) P. Kumm. (1871: 99), appartiene alla famiglia Pluteaceae Kotl. & Pouzar (1972: 218), è monofiletico e comprende specie non micorriziche con basidiomi morfologicamente caratterizzati da lamelle libere, una trama lamellare del tipo "bilaterale inversa", sporata rosa, basidiospore non amiloidi e cianofile, assenza di volva, cistidi imeniali a volte con apice coronato, mentre i giunti a fibbia possono essere presenti o assenti (Vellinga, 1990; Justo et al., 2011a). Singer (1986) stabilì la classificazione infragenerica di Pluteus in tre sezioni (Pluteus, Hispidoderma e Celluloderma), basate sulle loro caratteristiche morfologiche; Pluteus, sezione Hispidoderma Fayod, comprende specie con pileipellis del tipo trichoderma o imenoderma con elementi da cilindrici a fusiformi e prive di cistidi metuloidi. Vellinga & Schreurs (1985) hanno introdotto una nuova sezione Villosi Vellinga & Schreurs per specie con pileipellis con struttura di cutis e cistidi non metuloidi e la sottosezione Hispidodermini Vellinga & Schreurs inserita nell'ambito della sezione Celluloderma, comprendente taxa caratterizzati da una pileipellis con struttura di imenoderma o trichoderma provvista di elementi allungati. Moncalvo et al. (2002) hanno eseguito un'analisi filogenetica delle Agaricales includendo anche specie appartenenti al genere Pluteus, che risulta essere un gruppo monofiletico e suddiviso in due cladi ben distinti: il primo con specie appartenenti alla sezione Pluteus e il secondo con un complesso di specie appartenenti alle sezioni Hispidoderma e Celluloderma secondo la suddivisione proposta da Singer (1986). Le specie appartenenti alla sezione Hispidoderma presentano pileipellis con elementi cilindrici o fusiformi aventi un Q ≥ 3 e sono prive di cistidi metuloidi (Justo et al., 2011a). Materiali e metodi Morfologia Le descrizioni macroscopiche sono state fatte su materiale fresco, le fotografie sono state eseguite con fotocamera Canon EOS 600D. I caratteri micromorfologici si basano sullo studio del materiale sia fresco che secco; i campioni secchi sono stati reidratati in acqua distillata prima dell'osservazione e poi colorati con Rosso Congo anionico o Rosso Congo ammoniacale.
... Pluteus sect. Hispidoderma accommodates those species with non-metuloid pleurocystidia and a pileipellis consisting of elongated, filamentous elements organized as a cutis, hymeniderm, or trichoderm (Menolli & al. 2010;Justo & al. 2011aJusto & al. ,b, 2012Vizzini & Ercole 2011;Lezzi & al. 2014). ...
Pluteus umbrosoides and P. chrysaegis are reported as new records from China based on morphological observation and molecular evidence. Pluteus umbrosoides is characterized by a brown to dark brown squamulose pileus lacking an appendiculate pileus margin, a nearly glabrous stipe, ellipsoid basidiospores, predominantly capitate pleurocystidia, and a trichohymeniderm pileipellis. Pluteus chrysaegis is distinguished by its bright yellow pileus, subglobose to globose basidiospores, lageniform to fusoid cheilocystidia with long apical appendages, and abundant fusoid pleurocystidia. Morphologically and phylogenetically both species are members of P. section Hispidoderma. Morphological descriptions, illustrations, and line drawings of Chinese collections of the two species are provided.
... It is generally characterised by yellowish orange pileus colour when young which turns to light yellow later on. It differs from many other Pluteus species by having dimorphic pileipellis and caulocystidial elementsk (Lezzi et al., 2014). Macro and micromorphological characteristics of P. was compared with similar Pluteus species in Table 1. ...
This study was based on three macromycete samples collected during field studies carried out to determine the macrofungal biodiversity of Of and Çamburnu districts of Trabzon province (Turkey). As a result of necessary investigations, Pluteus variabilicolor Babos (Pluteaceae), Coprinopsis urticicola (Berk. & Broome) Redhead, Vilgalys & Moncalvo (Psathyrellaceae) and Chroogomphus confusus Y.C. Li & Zhu L. Yang (Gomphidiaceae) were recorded from Turkey for the first time. Brief descriptions and photographs related to macro-and micromorphologies of the species are provided together with their localities, geographical positions, collection date and Genbank number related to genetic sequences.
... Preferiamo, per il momento, non adottare la suddivisione proposta da VELLINGA & SChREURS (1985) in quanto studi molecolari effettuati da JUSTO (2011a, b, 2014) e LEZZI et al. (2014 hanno confermato la suddivisione morfologica nella sezione Pluteus, mentre la delimitazione tassonomica delle sezioni Celluloderma e Hispidoderma dovrà essere probabilmente ulteriormente chiarita per mezzo di nuove indagini molecolari e morfologiche. ...
Pluteus is a species-rich genus of saprotrophic agaric in the family Hispidoderma and is widely distributed in tropical, subtropical, and temperate areas throughout the world. Some species in this genus are threatened species according to the International Union for Conservation of Nature (IUCN) red list. During investigations of agarics in northern Thailand, four Pluteus taxa were collected. Morphological characteristics and phylogenic analyses were investigated. Two new species, namely P. chandrasikuliae and P. saisamorniae, were introduced. Pluteus chandrasikuliae is characterized by its relatively large basidiomata, an applanate, dark brown scaly pileus with a cutis pileipellis, two types of hymenial cystidia viz. irregular, as well as diverticulate cells and lageniform cells. In accordance with the phylogenetic results, this new species belongs to the Pluteus sect. Celluloderma. Moreover, P. saisamorniae is distinguished by a plano-convex with a broad umbo, dark brown minute squamules pileus, light brown lamellar edges, greyish orange stipe covered with brown granules, subglobose to broadly ellipsoid basidiospores, an abundance of thin- to thick-walled cheilocystidia and pleurocystidia, a trichohymeniderm pileipellis, and brown caulocystidia in clusters. Pluteus saisamorniae is a member of Pluteus sect. Hispidoderma. Additionally, P. losulus and P. septocystidiatus were discovered in Thailand for the first time and they belong to Pluteus sect. Pluteus. Comprehensive descriptions along with illustrations, photographs, phylogenetic trees showing their positions, and a comparison with phenetically similar taxa are provided.
