In Slovakia, two species of the genus Callistosporium are known, C. luteo-olivaceum and C. pinicola, both only with low number of collections and a brief description of macroscopic and microscopic characters. In this paper, information about all Callistosporium collections from Slovakia is gathered and data on species ecology, distribution and thre...

... The genus is characterized by the basidiomata with collybioid habit often fasciculate; pileus with a mixture of yellow, brown and olivaceus colours; the subdecurrent, adnexed or emarginated lamellae; ellipsoid, smooth, inamyloid basidiospores with scarcely or weakly cyanophilic, white deposit; presence or absence of cheilocystidia, pleurocystidia and clamp-connections; a cutis of pileipellis that contains hyphae with encrusting and intracellular pigments; and lilac, violet to olive yellow staining of flesh in KOH reaction (Singer, 1986;Noordeloos, 1995;Arnolds, 2006;Vesterholt and Holec, 2008;Halama and Rutkowski, 2014;Jančovičová et al., 2016;Sánchez-García et al., 2016). Callistosporium live as saprotrophic on humus, litter and also other kinds of wood debris, and on the base of palm trees and Sphagnum, mostly in forests (Singer, 1986;Noordeloos, 1995;Vesterholt and Holec, 2008;Jančovičová et al., 2016;Sánchez-García et al., 2016). ...

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.
... There are about 25 Callistosporium species names published (Kirk 2019). Most of the species has a collybioid habit, central stipe, abundant bright yellow necropigments in the spores, basidia and tramal hyphae usually turning lilac-purple in basic solutions, lacking clamp connections, and occurring in the Neotropics (Singer 1944;Bon 1976Bon , 1984Bon , 1991Verde and Calonge 1979;Redhead 1982;Gulden 1992;Noordeloos 1995;Vesterholt and Holec 2012;Jančovičová et al. 2016). It is thought that the yellow and brown colours of Callistosporium basidiomes are due to unstable, dimeric anthraquinone pigments that oxidate producing colour shifts (darkening) in living and dried basidiomes (Høiland 1984;Moser 1986). ...

It grows saprotrophically usually on decaying conifer wood (logs, trunks, stumps, debris), mostly Pinus spp. ...
... Genetic data agree also with the conclusions obtained by Moser (1986) after the study of anthraquinone pigments, where the existence of several taxa within the C. luteo-olivaceum complex was already suggested. Callistosporium luteo-olivaceum is characterized by a pileus with yellow-olive tinges, bright yellow (when young) crowded lamellae (always distinctly contrasting in colour with the pileus), basidiome surface turning lilac-purple in basic solutions, presence of skyrin and hypericin (dimeric anthraquinone pigments), and spores hardly reaching 7 μm in length (Moser 1986;Holec 2012, Saba andKhalid 2014;Martin 2012;Jančovičová et al. 2016; Picciola and Zugna 2017 and this work), in fact these measure 4-6.5 × 3-4 μm in the type collection according to Roberts (2008). Callistosporium graminicolor, a species proposed by Lennox (1979) for specimens found in the state of Washington (USA), differs from C. luteo-olivaceum mainly because of its larger spores (6-8 × 4-5.5 μm), and seems to represent an autonomous species (Fig. 3) based on the genetic data obtained from collection PBM 2341 (WTU-F), found in the trail to Barclay Lake, Snohomish County, Washington state (USA), on rotten conifer stump, 670 m a.s.l., on 14-Jul-2002, leg. ...
A new classification of the taxa formerly ascribed to Biannulariaceae (≡ Catathelasmataceae), viz. Catathelasma (type), Callistosporium, Pleurocollybia, Macrocybe, Pseudolaccaria, Guyanagarika and Anupama is here proposed. Phylogenetic inference of the Tricholomatineae based on the analysis of a combined dataset of nuclear genes including ITS, 18S and 28S rDNA, tef1 and rpb2 data supports significantly a monophyletic origin of the aforementioned genera with the exception of Catathelasma, which is significantly related with Bonomyces and Cleistocybe. Biannulariaceae is therefore emended to include the clade formed by Catathelasma, Bonomyces and Cleistocybe. Consequently, the new family Callistosporiaceae is proposed to name the clade containing Callistosporium (= Pleurocollybia) and related genera. Species of Callistosporium with distant lamellae, long hygrophoroid basidia and large amygdaliform spores are accommodated in the new genus Xerophorus. Finally, the new species Callistosporium pseudofelleum and Macrocybe sardoa are described, Clitocybe hesleri and C. fellea are combined into Callistosporium and Pseudolaccaria, respectively, and Callistosporium olivascens var. donadinii is upgraded to species rank and combined into Xerophorus.
z: Xerophorus donadinii (Bon) Vizzini, Consiglio & M.Marchetti türüne ait bazidiyomalar 2018 yılı Ekim ayında Trabzon'dan toplanmış, morfolojik verilere göre betimlenmiş, makalede arazi ve laboratuvar resimleri ve kısa bir tartışma ile birlikte Türkiye için cins düzeyinde yeni kayıt olarak sunulmuştur. Bazidiyomalar kolybioid görünümlü, birçoğu bir arada yetişir, Abstract: Basidiomata belong to the species of Xerophorus donadinii (Bon) Vizzini, Consiglio & M.Marchetti were collected from Trabzon in October 2018, were described according to morphological data and are presented herein as a new genus record for Turkey together with field and laboratory images and a brief discussion. The basidiomata have the appearance of collybioid mushrooms, many of them grow together; pileus surface is greenish yellow, pale reddish brown or wine color; the lamellae are pale lemon yellow at the beginning, wine-color in places over time; its texture is brittle, basidiospores are on average 7.7 × 5.4 µm, almond-shaped or elliptical, containing one or more pale green droplets.
