... Clitopilus brunneiceps has a wide distribution from southwest to northeast China, differing from C. highlandensis by its grey pileus, filamentous hyphae (4-10 μm in diam.) in lamellar trama and pigments in pileipellis (Jian et al. 2020a). Clitopilus fusiformis is a subalpine species, but grows at higher places (> 3400 m) with larger and fusiform basidiospores (10.5-14 × 5-7 μm) (Wang et al. 2017). The neotropical species C. griseobrunneus occurs in Costa Rica, charactered with medium to large-sized fruit body, brown pileus, larger and amygdaliform basidiospores (9.7-16.9 ...
In this study, two new species, namely Clitopilus highlandensis and C. subalbidus, are proposed based on morphological and molecular analyses. Clitopilus highlandensis differs from C. abprunulus by its greyish yellow and convex pileus, and larger basidiospores. Clitopilus subalbidus is similar to C. albidus but distinguished from the latter by its inflated hyphae in the lamellar trama and bigger basidiospores. The evidence from the phylogenetic tree constructed with RNA polymerase II second largest subunit (RPB2) further supports the morphological taxonomy. The phylogenetic tree, comprehensive descriptions , photographs, macro-and microscopic comparisons are presented.

... In China, a fair number of taxonomic studies on Clitopilus and allies have been conducted (Chang and Mao 1995;Bi et al. 1997;Yang 2000Yang , 2007Zang 2001;Li et al. 2008Li et al. , 2015Deng et al. 2010Deng et al. , 2013aDeng et al. , 2013bYuan and Sun 2013;Wang et al. 2017). However, based on our field work, there are still species of Clitopilus and allies to be recognized. ...
Within the family Entolomataceae, many reports of Entoloma and Rhodocybe have been published, but few reports on Clitopilus and allied genera are available. In this study, Clitopilus, Clitocella, and Clitopilopsis from China were studied by morphological and phylogenetic methods. Portions of nuc 28S rDNA (28S), RNA polymerase II second largest subunit (rpb2), translation elongation factor 1-alpha (tef1), and ATPase subunit 6 (atp6), were employed to elucidate the relationships of Clitopilus and allies. Results indicate that Clitopilus should be divided into three sections, namely, sect. Clitopilus, sect. Scyphoides, and sect. Crispi, the last of which is newly described. In total, 17 species of Clitopilus, Clitocella, and Clitopilopsis are found in China; 14 species belong to Clitopilus, of which 5 are new: C. yunnanensis, C. brunniceps, C. rugosiceps, C. sinoapalus, and C. umbilicatus. Two species of Clitocella, including one new species, Clitocella orientalis, are described. One new species of Clitopilopsis, namely, Clitopilopsis albida, is proposed.
... Clitopilus is a small genus estimated to contain about 30 species worldwide and most of the known species are from the north temperate regions (Kirk et al. 2008). Monographic treatments of the genus are not available and only sporadic reports describing new species or new records are available (Pegler 1977a(Pegler , b, 1986Redhead & Baroni 1986;Noordeloos 1988Noordeloos , 1993Baroni & Watling 1999;Hausknecht & Noordeloos 1999;Baroni & Halling 2000;Baroni et al. 2001;Noordeloos et al. 2010;Deng et al. 2013;Cooper 2014;Morgado et al. 2016;Wang et al. 2017).

Three species of Clitopilus, C. albidus sp. nov., C. subscyphoides and C. orientalis, are described from Kerala State, India, based on morphology and molecular phylogeny. Comprehensive descriptions, photographs, and comparisons with phenetically similar and phylogenetically related species are provided. The RNA polymerase II genes (rpb2) of the three species were sequenced and analyzed. In addition, the nuclear ribosomal internal transcribed spacer regions (ITS) and the nuclear ribosomal large subunit (nLSU) genes were sequenced and used in BLAST searches to find similar sequences. Phylogenetic analyses based on rpb2 sequences performed using both Maximum Likelihood (ML) and Bayesian Analysis (BA) methods supported the novelty of C. albidus and its placement within the genus Clitopilus. C. subscyphoides and C. orientalis are the first and second record respectively of these species from India.
A new species, Clitopilus cretoalbus A.Izhar, Zaman, M.Asif, H.Bashir, Niazi & Khalid sp. nov.,is described herein based on several collections from Punjab, Pakistan.It is characterized by a clitocyboid to somewhat omphaloid stature combined with a white pileus, decurrent lamellae, an almost central to slightly eccentric whitish relatively long stipe, the occurrence of cheilocystidia, and basidiospores with 6 to 9 ridges in polar view. Molecular phylogenetic analyses of nrITS and nrLSU performed using the maximum likelihood method supported the novelty of this Pakistani species and its placement within the genus Clitopilus section Scyphoides. A comparison with other morpho-anatomically close species confirmed that the newly described species is distinct from others.
A novel mushroom species occurring on loamy soil under Bombax cieba was collected from Chichawatni forest, Punjab, Pakistan. Phylogenetic analyses of the nrDNA ITS and nuLSU regions revealed that it clusters within the genus Clitopilus. Further morpho-anatomical analyses confirmed its uniqueness, which is referred as a new species under the name Clitopilus chichawatniensis. The distinguishing characteristics of this novel taxon are large whitish to light pale, eccentric pleurotoid pileus 50–65 mm wide with lobed and involuted margins, large ovoid to ellipsoid basidiospores 6.2–8.4 × 4.8–6.4 µm with 3–5 longitudinal ridges, absence of cheilocystidia and pleurocystidia. A detailed description of this taxon and a key to all existing species of the genus Clitopilus in Pakistan is provided.
Based on morphological and phylogenetic investigations, four new species, Clitocella termitophila, Clitopilus velutinus, Rhodocybe dominicana, and Rhodocybe pseudoalutacea, one new variety, Rhodocybe luteocinnamomea var. fulva, and first reports of Clitopilus prunulus, Rhodocybe mellea, and Rhodocybe roseiavellanea are described and illustrated from the island of Hispaniola. Three protein coding genes, RPB2, TEF1, and ATP6, were used to compare taxa and make phylogenetic inferences about novel species and varieties. Where necessary, because of non-availability of these protein coding gene data for every taxon, ITS sequences were used to confirm uniqueness or species similarity for C. velutinus and R. mellea, respectively. This contribution is a result of and based on numerous expeditions in the Dominican Republic by two different groups over a 20-year period that were designed to gather data on macrofungal biodiversity of this region. The new agaric taxa documented here contribute to the limited but growing knowledge on biodiversity of the Entolomataceae (Agaricales) for the Dominican Republic and the island of Hispaniola.
In this study, Clitopilus abprunulus (Entolomataceae, Agaricales) is described as a new species based on collections from North Macedonia with both morphological and molecular evidence. It differs from other species in Clitopilus by its grayish pileus, eccentric stipe, and inflated cells in the lamellar trama. The nuclear ribosomal internal transcribed spacer (ITS) regions were sequenced and used for phylogenetic analyses. The results based on ITS sequences using both Maximum Likelihood (ML) and Bayesian Inference (BI) methods indicated that the new species was distinct from other species. The systematic position of the pleuromutilin-producing taxa in Clitopilus was elucidated, it was found that all of them were clustered into a single lineage within C. section Scyphoides. In addition, an epitype for C. ravus is designated, and the shape changes of the basidiospores of this taxon during their development are discussed.
A new species of agaricomycetes, Clitopilus lampangensis , is described based on collections from northern Thailand. This species was distinguished from previously described Clitopilus species by its pale yellow to grayish yellow pileus with the presence of wider caulocystidia. Molecular phylogenetic analyses, based on the data of the internal transcribed spacers (ITS) and the large subunit (LSU) of the nuclear ribosomal DNA, and the second largest subunit of RNA polymerase II ( rbp2 ) genes, also support the finding that C. lampangensis is distinct from other species within the genus Clitopilus . A full description, color photographs, illustrations and a phylogenetic tree showing the position of C. lampangensis are provided.
