“…The specimens were dried in a dehydration machine at 30 °C for 24 h, packed in plastic bags, and then stored. The colour codes used follow the Munsell Soil Color Charts (Munsell 1975). Micro-morphological examinations of the dried specimens were done with free-hand sections mounted in 5% potassium hydroxide (KOH) (w/v), 1% Congo red (w/v), and/or distilled water, followed by observation with a light microscope.…”

“…The genus is traditionally divided into up to 13 subgenera, based on morphological characteristics such as form of the basidiomata, structure of the pileipellis, shape of the basidiospores, presence/absence and shape of cystidia, and presence/absence of clamp connections (Romagnesi 1978;Noordeloos 1981Noordeloos , 2004Noordeloos and Gates 2012). These traditionally defined subgenera are treated at the rank of genera by some authors (Largent 1994; Baroni and Lodge 1998;Aime et al 2010;Baroni and Halling 2000;Karstedt et al 2020;Niveiro et al 2022). Phylogenetic studies (Co-David et al 2009) show that these subgenera in many cases are not monophyletic.…”

Entoloma is one of the largest genera of Agaricales in terms of species diversity and is widespread throughout the world. In the present study, four new species, namely Entoloma brunneofibrillosum, E. humidiphilum, E. ochraceodiscum, and E. colchicum, are introduced as new to science. These species are described based on specimens collected in Cyprus, Georgia, Hungary, Italy, Russia, Spain, and Türkiye, including morphological characteristics and phylogenetic analyses of the nuclear ribosomal DNA internal transcribed spacer (ITS) sequences. Entoloma brunneofibrillosum is recognized by its brown to dark brown pileus with conspicuous dark, radial fibrils, a pale brown stipe with glistening fibrils, and usually fusiform to broadly clavate cheilocystidia. It belongs to the /Undulatosporum clade. Entoloma humidiphilum (subg. Alboleptonia) is close to E. niveum from New Zealand but differs by a completely pruinose or minutely squamulose pileus surface, narrowly cylindrical to cylindrical pileipellis elements with a deep median constriction, and by occurring in riparian habitats. Entoloma ochraceodiscum is characterized by funnel-shaped basidiomata with a deeply depressed yellowish-brown pileus and belongs to the section Griseorubida. Entoloma colchicum (subg. Nolanea) is similar to E. ortonii but differs by its distinctive radially fibrillose or velutinous pileus and the absence of odour. The new species are presented with photographs, line drawings, and comparisons with similar taxa.
