“…Singer (EF413030) reported from Spain is also closely related to the new species separated by strong bootstrap support (BS = 75%). The newly generated sequences of the Pakistani species clustered with other species from section Scyphodies (Morgado et al 2016;Wang et al 2017;Raj & Manimohan 2018;Kumla et al 2019;Baroni et al 2020aBaroni et al , 2020bFatima et al 2022;Rehman et al 2022).…”

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.

“…Clitopilus (Entolomataceae, Agaricales, Basidiomycota) is considered as a common saprotrophic genus (Raj & Manimohan, 2018), and several members in the Entolomataceae family can form ectomycorrhizae with a wide range of tree species (Agerer & Waller, 1993). Although field investigations suggested that Clitopilus orcella and C. subvilis are putative ectomycorrhizal fungi (ECM) associated with Quercus petraea (Southworth, 2013) and Q. robur (Howe, 1964;Keizer & Arnolds, 1994), as well as other trees in the Fagaceae family (Molina, Massicotte, & Trappe, 1992), the ability of Clitopilus spp.…”

Facultative symbiosis with a saprotrophic soil fungus promotes potassium uptake in American sweetgum trees

Several species of soil free-living saprotrophs can sometimes establish biotrophic symbiosis with plants, but the basic biology of this association remains largely unknown. Here, we investigate the symbiotic interaction between a common soil saprotroph, Clitopilus hobsonii (Agaricomycetes), and the American sweetgum (Liquidambar styraciflua). The colonized root cortical cells were found to contain numerous microsclerotia-like structures. Fungal colonization led to increased plant growth and facilitated potassium uptake, particularly under potassium limitation (0.05 mM K + ).The expression of plant genes related to potassium uptake was not altered by the symbiosis, but colonized roots contained the transcripts of three fungal genes with homology to K + transporters (ACU and HAK) and channel (SKC). Heterologously expressed ChACU and ChSKC restored the growth of a yeast K + -uptake-defective mutant. Upregulation of ChACU transcript under low K + conditions (0 and 0.05 mM K + ) compared to control (5 mM K + ) was demonstrated in planta and in vitro. Colonized plants displayed a larger accumulation of soluble sugars under 0.05 mM K + than non-colonized plants. The present study suggests reciprocal benefits of this novel tree-fungus symbiosis under potassium limitation mainly through an exchange of additional carbon and potassium between both partners.

“…It belongs to the family Entolomataceae of the order Agaricales. This genus is saprotrophic and is widely distributed, especially in northern temperate areas (Singer 1986; Baroni and Watling 1999; Moncalvo et al 2002; Kirk et al 2008; Hartley et al 2009; Crous et al 2012; Raj and Manimohan 2018). Clitopilus is characterized by basidiocarps that are clitocyboid, omphalinoid or pleurotoid, mostly whitish or occasionally grayish or brownish in color, with pink or pinkish brown spore prints, ellipsoid basidiospores with longitudinal ridges that appear angular in a polar view, and hyphae lack clamp connections (Singer 1986; Noordeloos 1988).…”

“…Formerly, the genus Clitopilus included Rhodocybe (Moncalvo et al 2002; Co-David et al 2009; Vizzini et al 2011a). However, molecular phylogenetic analyses have provided powerful tools for the identification of Clitopilus , leading to the separation of Clitopilus from Rhodocybe as well as the related genera ( Clitocella and Clitopilopsis ) (Cooper 2014; Kluting et al 2014; Raj and Manimohan 2018).…”

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.
