... Notes: The molecular circumscription of the limits of the family was first carried out by Vizzini et al. (2020a). It is characterized by basidiomes with tricholomatoid, clitocyboid or pleurotoid habit; lamellae adnate, adnexed, sinuate, emarginate to decurrent; partial veil present (simple or double) or inconsistent and reduced to a granular, pseudoanular zone at the apex of the stipe; odour usually farinaceous; spore deposit white; basidiospores ellipsoid to fusoid, cylindrical, colourless, smooth, inamyloid or amyloid, acyanophilous or cyanophilous; basidia lacking siderophilous inner bodies; cheilocystidia present or absent, pleurocystidia absent or if present then only as pseudocystidia; hymenophoral trama regular to bilateral becoming regular, pileipellis a cutis, an ixocutis or a cutis becoming a trichoderm, context (pileitrama and stipititrama) formed by densely arranged slender hyphae which give rise to a dry and fibrous consistency, clamp connections present. ...
The phylogenetic position of several clitocyboid/pleurotoid/tricholomatoid genera previously considered incertae sedis is here resolved using an updated 6-gene dataset of Agaricales including newly sequenced lineages and more complete data from those already analyzed before. Results allowed to infer new phylogenetic relationships, and propose taxonomic novelties to accommodate them, including up to ten new families and a new suborder. Giacomia (for which a new species from China is here described) forms a monophyletic clade with Melanoleuca (Melanoleucaceae) nested inside suborder Pluteineae, together with the families Pluteaceae, Amanitaceae (including Leucocortinarius), Limnoperdaceae and Volvariellaceae. The recently described family Asproinocybaceae is shown to be a later synonym of Lyophyllaceae (which includes also Omphaliaster and Trichocybe) within suborder Tricholomatineae. The families Biannulariaceae, Callistosporiaceae, Clitocybaceae, Fayodiaceae, Macrocystidiaceae (which includes Pseudoclitopilus), Entolomataceae, Pseudoclitocybaceae (which includes Aspropaxillus), Omphalinaceae (Infundibulicybe and Omphalina) and the new families Paralepistaceae and Pseudoomphalinaceae belong also to Tricholomatineae. The delimitation of the suborder Pleurotineae (= Schizophyllineae) is discussed and revised, accepting five distinct families within it, viz. Pleurotaceae, Cyphellopsidaceae, Fistulinaceae, Resupinataceae and Schizophyllaceae. The recently proposed suborder Phyllotopsidineae (= Sarcomyxineae) is found to encompass the families Aphroditeolaceae, Pterulaceae, Phyllotopsidaceae, Radulomycetaceae, Sarcomyxaceae (which includes Tectella), and Stephanosporaceae, all of them unrelated to Pleurotaceae (suborder Pleurotineae) or Typhulaceae (suborder Typhulineae). The new family Xeromphalinaceae, encompassing the genera Xeromphalina and Heimiomyces, is proposed within Marasmiineae. The suborder Hygrophorineae is here reorganized into the families Hygrophoraceae, Cantharellulaceae, Cuphophyllaceae, Hygrocybaceae and Lichenomphaliaceae, to homogenize the taxonomic rank of the main clades inside all suborders of Agaricales. Finally, the genus Hygrophorocybe is shown to represent a distinct clade inside Cuphophyllaceae, and the new combination H. carolinensis is proposed.
... Bon (1990, 1991 considered it to be a subgenus within Callistosporium Singer (1944: 363). However, a recent study by Vizzini et al. (2020) revealed that species of Xerophorus formed a distinct lineage and considered a separate genus within the family Callistosporiaceae. The species of this genus are characterized by widely spaced, thick lamellae, hygrophoroid basidia up to 50 µm long, poorly differentiated, or absent cheilocystidia, absence of pleurocystidia, whitish spore print, smooth amygdaliform spores up to 10 µm long, a bluish green reaction in basic solutions, and a cutis to subtrichoderm pileipellis type (Vizzini et al. 2020). ...

Vizzini, Consiglio & M. Marchetti (2020: 239) from Europe, and X. dominicanus Angelini, Vizzini & Bizzi (2020: 243) from the Dominican Republic (Vizzini et al. 2020). ...
A novel species, Xerophorus pakistanicus, has been identified from Southern Punjab, Pakistan, based on morphological characters and molecular phylogenetic analyses. Xerophorus pakistanicus is characterized by a brown to dull orange, parabolic to campanulate pileus, a stipe turning light yellowish brown on handling, an absence of an annulus, amygdaliform to oblong basidiospores, utriform to pyriform caulocystidia, and the presence of clamp connections only in the stipitipellis. A phylogram, based on the combined nrITS-28S dataset, was constructed to assess the phylogenetic position of our strain, resulted Xerophorus pakistanicus sp. nov. within the genus Xerophorus. We present the new species with an illustrated morphological description and comparison with similar morphological or phylogenetically related species. This is the first record of the genus Xerophorus from Asia. A key to the known species of Xerophorus is also provided.
... In addition, Bonomyces Vizzini is macroscopically quite similar to Infundibulicybe. However, Bonomyces species exhibit ellipsoid basidiospores with an obtuse base and a thick lateral apiculus, and inflate, not completely parallel hyphae with some vesicular elements in the mediostratum of lamellae (Alvarado et al. 2018;Vizzini et al. 2020). ...
In China, species of the genus Infundibulicybe are often confused with other taxa and misdeter-mined. Here we describe two newly discovered species, I. bispora and I. ellipsospora, and redescribe five known taxa of this genus present in China. These identifications are supported by both morphological and DNA-based phylogenetic evidence. Additionally, a key to all known species of Infundibulicybe is provided.
... Bon, currently X. olivascens (Bon) Vizzini, Consiglio & M.Marchetti, which prefers association with cedar trees. Further differences are also morphological: X. donadinii has pilei with smaller diameters, without an evident umbo, with a more reddish shade in the centre, and a paler and more involute edge; the stipe is also slenderer than in X. olivascens (Courtecuisse and Duhem 1995;Vizzini et al. 2020). In Italy, X. donadinii has so far been reported always on broadleaved trees, only in Emilia-Romagna, Marche, and Puglia (Vizzini et al. 2020 Printzen 1995); its distribution is now extended to Val Masino. ...

... Micromorphological features, such as non-amyloid spores, sub-regular to irregular hymenophoral trama and pileipellis with encrusting pigment, are shared by all members of the genus Omphalina s. stricto [2,9,[25][26][27][28][29]. This genus is sister to Infundibulicybe [14,21,[30][31][32], and together they form the family Omphalinaceae [33] in the suborder Tricholomatineae. ...
The genus Omphalina is an ideal genus for studying the evolutionary mechanism of lichenization. Based on molecular phylogeny using ITS and nuLSU sequences by means of Bayesian and maximum likelihood analyses and morphological examination, combining the existence of green algae in basidiomata stipe and a Botrydina-type vegetative thallus, we described a bryophilous new basidiolichen species, Omphalina licheniformis, from a residential area of Jiangxi Province, China. This finding of unusual new basidiolichen species updated our understanding of the delimitation of Omphalina, indicating that both non-lichen-forming and lichen-forming fungal species are included simultaneously. The presence of algal cells in the basidiomata should receive more attention, as this would be helpful to distinguish more potential basidiolichens and explore the cryptic species diversity. This work provides new insights and evidence for understanding the significance of lichenization during the evolution of Agaricomycetes.

... In Turkey, only one collection named Callistosporium olivascens (Boud.) Bon. was reported as belonging to the genus Callistosporium (Akata et al., 2020); however, this species was combined into genus Xerophorus (Vizzini et al., 2020). Recently, the first member, Xerophorus donadinii (Bon) Vizzini, Consiglio & M. Marchetti, has been presented at genus level from Turkey (Sesli, 2021). ...
... However, they have distinctive morphological characteristics that differentiate each other. Callistosporium elegans differs from C. luteo-olivaceum mainly by its violet to purple-wine pileus, smaller basidiospores (4.4-5.3 × 3.0-3.7 μm) and cylindraceous, subcapitate to bilobed cheilocystidia (Vizzini et al., 2020). ...
Callistosporium luteo-olivaceum collected from Mediterranean region of Turkey is identified based on morphological characters and combined dataset of nuclear ribosomal ITS and LSU sequences. Callistosporium luteo-olivaceum is new to the country’s mycobiota and it is the first report of this species from the relict endemic Liquidambar orientalis forest. Description of the species based on macro and micromorphological characters, colour photograph from its natural habitat and line-drawings of microscopic features are presented.
... 3,4 Among these species, the current investigation mainly sheds light on M. gigantea, a common edible mushroom that belongs to the family Tricholomataceae, grows in regions of high temperature and humidity, and is distributed in subtropical rain forests of Africa and Asia. 5,6 In India, the species was documented from Kerala, Karnataka, and West Bengal. [7][8][9] M. gigantea is mainly appreciated for its sweet taste and attractive flavor and is utilized as a home remedy in Asia. 10 Its medicinal properties include antibacterial, antioxidant, and antitumor activities. ...
Macrocybe gigantea is an edible mushroom and has multiple pharmacological activities such as antibacterial, antioxidant, and antitumor activities. However, only a few reports were available on the bioactive compounds and bioactivity of this mushroom. In this concern, the present study was aimed to explore the unique chemical diversity from the fruiting body of M. gigantea. The species identification was done accurately with morphological and molecular methods followed by mycochemical extraction in different solvent systems. The ethanolic extract of the fruiting body gave maximum yield and its Gas Chromatography-Mass Spectrometry (GC-MS) analysis was performed along with antibacterial activity and cell viability by MTT assay. The GC-MS analysis revealed 50 metabolites and further chemoinformatics analysis of these metabolites revealed their possible biological activities. In addition, the mushrooms' physico-chemical and mineral element analysis revealed the quality and authenticity of the species. Altogether, the current investigation gives a comprehensive overview of the bioactive metabolites of Macrocybe gigantea.

The species of the genus Xerophorus is characterized with spaced, thick lamellae, hygrophoroid basidia up to 50 µm long, whitish spore-print, smooth and amygdaliform spores up to 10 µm long, and a bluish-green reaction in basic solutions [3]. They grow mainly on soil. ...
... They grow mainly on soil. Only three species of this genus have been identified so far, which are Xerophorus donadinii ( [3]. Xerophorus donadinii is regarded as an European macrofungi restricted to the Mediterranean regions. ...
... Xerophorus donadinii is regarded as an European macrofungi restricted to the Mediterranean regions. It is only reported from Italy, France and Hungary [3]. Additionally, only a morphological description of this species is reported from Black Sea region in Turkey [4]. ...
Xerophorus donadinii (Bon) Vizzini, Consiglio & M. Marchetti has been identified from the Mediterranean Region of Turkey based on morphological characters and molecular phylogenetic studies. A combined dataset generated from nuclear ribosomal internal transcribed spacer and nuclear ribosomal DNA large subunit gene sequences is used to assess its position within Callistosporiaceae. Color photographs from its natural habitat, morphological descriptions and line-drawings of microscopic characters are provided.
... The overall topology in Figure 1 (the topology of the tree was obtained from Bayesian analysis) is consistent with the topologies published in previous studies [22,[30][31][32][33][34][35][36][37][38], except for the positions of the genera Bonomyces, Catathelasma, and Cleistocybe. Sánchez-García et al., Alvarado et al., and Raj et al. also reported results similar to those of the present study [34][35][36][37]. ...
... Sánchez-García et al., Alvarado et al., and Raj et al. also reported results similar to those of the present study [34][35][36][37]. Vizzini et al. explained that this difference in arrangement is due to the taxon sampling within Catathelasma, Callistosporium, and Macrocybe [38]. In the additional analyses, we obtained the same results as Vizzini et al. when increasing the sampling within Catathelasma, Callistosporium, and Macrocybe (not shown in the present study). ...
... Morphologically, the species of Asproinocybe and Tricholosporum are somewhat similar to those of Callistosporiaceae. They have the same features: tricholomatoid habit, veils absent; lamellae adnate, adnexed, sinuate, emarginated to decurrent; spore print white, spores cyanophilous or acyanophilous, thin-walled; hymenophoral trama regular; and pileipellis arranged as a cutis [38]. All the species of Asproinocybe and Tricholosporum are more or less purplish, violaceous, or lilac-vinaceous; the species of Callistosporiaceae can also have similar coloration, such as Callistosporium elegans. ...
Asproinocybe and Tricholosporum are not well known, and their placement at the family level remains undetermined. In this study, we conducted molecular phylogenetic analyses based on nuc rDNA internal transcribed spacer region (ITS) and nuc 28S rDNA (nrLSU), and a dataset with six molecular markers (ITS, LSU, RNA polymerase II largest subunit (RPB1), RNA polymerase II second largest subunit (RPB2), 18S nuclear small subunit ribosomal DNA (nrSSU), and translation elongation factor 1-alpha (TEF1-α)) using Bayesian (BA) and Maximum Likelihood (ML) methods, we found that the species of Asproinocybe and Tricholosporum formed an independent family-level clade (0.98/72). Asproinocybaceae fam. nov., a new family, is established here for accommodating this clade. Two new species, Asproinocybe sinensis and Tricholosporum guangxiense, from subtropical and tropical karst areas of China, are also described here.
