... P. Kumm. as the type species. This genus is saprotrophic and widely distributed in both tropical and temperate areas (Singer and Smith 1958;Guzmán 1978Guzmán , 1983Redhead et al. 2007;Kirk et al. 2008), while Psilocybe sensu lato is known to include Deconica. Both Psilocybe and Deconica have been characterized by typically hygrophanous basidiomata, brown to yellow-brown pileus, lilac-brown to dark brown to dark purple-brown spore prints, ellipsoid to rhomboid to subhexagonal basidiospores with a distinct apical germ pore (Singer and Smith 1958;Guzmán 1978Guzmán , 1983Redhead et al. 2007). ...
... The protected forest habitats at Tara Mt. stand out, not only in terms of the total number of recorded species but also the presence of species that are interesting from a conservational perspective. Among them are species specialized in mosses as a specific substrate: Galerina hypnorum, Rickenella fibula, Rickenella swartzii, and Entocybe nitida, which are recognized as potential indicators of wet forest habitats [88][89][90]. Hericium coralloides and Mycena laevigata found at plot 5 are indicator species of valuable old forests [87,91,92] and together with the other values of this peripheral part of the Nature Reserve Crveni potok may serve for the consideration of the expansion of a strictly protected area. ...
... In contrast, the Matlanzinca shamans refer to Psilocybe wassonii (Syn. =Psilocybe muliercula) as netocuhuatata (the holiest of lords), and the Nahuatl of San Pedro Nexapa refer to them as "the noble prince of the waters (Schultes, 1939(Schultes, , 1940(Schultes, , 1969Singer & Smith, 1958;Heim, 1963;Schultes, 1978;Guzman, 1977Guzman, , 1983Guzman, , 1990Wasson, 1957Wasson, , 1974Schultes & Hofmann, 1979;Santesson, 1939;Rubel & Gelter-Finger Krejci, 1976;Miller, 1966;Lipp, 1990;Hoogshagenii, 1959;Hernandez, 1651;Serna, 1892;Kingsborough, 1848). ...
... A special mechanical construction inside a cushion is not essential, because the stems of bryophytes stabilise the stipe of the fruiting body (Kost 1988). Some associations between mosses and representatives of the genus Galerina are constant enough to be used as taxonomic guides (Redhead 1981), for example: Smith & Singer (1964), Horak & Miller (1992), Gulden (1992, 2012), Watling et al. (1993), Kränzlin (2000), Wood (2001), Haan & Walleyn (2002). The majority of them belong to the saprotrophic fungi, growing on rotting wood, woody or herbal debris, peat, grass turf, humus, sand, silt or clay (Smith & Singer 1964, Watling et al. 1993, Gulden 2012) and produce enzymes that are effective at decomposing components of the moss cell walls (Davey et al. 2013). ...
... Gasteroid Russulales are indeed particularly well-represented and well-studied in Australia and New Zealand (Bougher 1997, Bougher & Lebel 2001, Lebel 2001, 2002, 2003a, b, Lebel & Castellano 2002) and North America (Zeller & Dodge 1919, 1936, Singer & Smith 1960, Smith 1963, Thiers 1984b, Miller & Lebel 1999, Desjardin 2003, Smith et al. 2006). Tropical records seem rare and occasional. ...
... Chroogomphus also includes one species, C. albipes, which is currently unique in the genus due to the secotioid basidiomata. Because of this and other unusual morphological characters, this species was originally described as Secotium albipes (Zeller 1948) and then recombined as Brauniellula albipes (Smith & Singer 1958); however, molecular studies have shown that it belongs to Chroogomphus (Miller 2003). Brauniellula would normally have priority over Chroogomphus, but the latter name was conserved over it by Aime & Miller (2006); it is now accepted as the correct name of the genus. ...
... Moreover, the East Asia fungi exhibit a close relationship with those in Southeast Asia and Australia (Halling et al. 2008;Tedersoo et al. 2010;Tedersoo and Smith 2013;Han et al. 2018), and the endemism of fungi in the Asia-Pacific region is high as well. Taking the boletoid macrofungi as an example, hundreds of new and endemic boletes can be found in the pertinent literature (Singer 1944;Chiu 1948;Hongo 1960Hongo , 1973McNabb 1967McNabb , 1968Corner 1972Corner , 1974Horak 1977Horak , 2011Bi et al. 1982Bi et al. , 1984Zang 1985Zang , 2006Zang , 2013Li and Watling 1999;Watling and Li 1999). The data published in the aforementioned contributions could probably account for 1/4 to 1/3 of all boletes found and published so far in the world. ...
... The genus Pseudoboletus is resolved as the sister group of all ectomycorrhizal Boletaceae species and includes only two described species, both of which are considered mycoparasites (Binder and Hibbett, 2006;Nuhn et al., 2013). Pseudoboletus parasiticus fruits directly on Scleroderma citrinum but has also been reported growing on other Scleroderma species (Singer, 1986;Smith and Thiers, 1971). Pseudoboletus astraeicola fruits directly on Astraeus hygrometricus (Šutara, 2005). ...
... Singer lived and worked in Tucumán, Argentina, from 1948 to 1960, and during this time he contributed to the knowledge of Bolivian Agaricales with the description of 200 agaric species in 22 publications (Mueller et al. 1997, Singer 1958, 1960, 1962a, 1973, 1989, Singer & Smith 1958, Smith & Singer 1964. ...
... By contrast, Th. violaceum had a less well-developed stipe, obvious violaceous tones, and the peridium typically remained attached to the stipe. Horak and Moser (1965), Horak (1979), and Gamundi and Horak (1993), among other authors, also employed a species concept that changed over time and was notably different from the original description of Singer (1951) and later the description of Singer and Smith (1958). Horak and Moser (1965) noted the differences in the magnitude and distribution of the spore ornamentation among collections at IB, but they nonetheless concluded that these specimens all belonged to the same species, Th. magellanicus. ...
