... Esta especie forma parte de la Sección Cubensae (Guzmán, 1983), Tribu Cubensis (Singer & Smith, 1958). En regiones tropicales, puede confundirse con especies similares como P. subcubensis Guzmán y P. aquamarina (Pegler) Guzmán, las cuales se distinguen de P. cubensis por el tamaño más pequeño de sus esporas, 10-11 (12) µm en P. aquamarina (Pegler, 1977 como Stropharia aquamarina) y 11-13 (14) × 7,7-8,8 en P. subcubensis (Guzmán et al., 2014). ...

... & Singer prefers open grassy areas. However, G. brunneimarginata and G. semilanceata differ from G. venenata in the colour and characteristics of the pileus, the small size of the basidiospores, and the absence of pleurocystidia (Smith and Singer, 1964). ...

... 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). ...

... Historically, sequestrate fungi have been grouped together artificially into unique genera and even higher-level taxa based on gross morphology, even though phylogenetic links to nonsequestrate fungi such as mushrooms (with agaricoid fruit-bodies) have long been recognised (e.g. Singer 1951;Singer and Smith 1959;Thiers 1984;Albee-Scott 2007). It is now clear from well supported molecular phylogenies that many genera established for sequestrate fungi are nested within otherwise nonsequestrate (agaricoid, boletoid) genera; indeed, sequestrate taxa are often polyphyletic within these genera (e.g. ...

... 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. ...

This common microscopic appearance demonstrated that the family is a natural group and evolutionary molecular analysis showed its monophyly (David et al,. 2009, Baroni andMatheny 2011 (Singer 1986;Nooedeloos 1993).

... 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. ...

... Singer (1951) established Thaxterogaster as a sequestrate genus to accommodate taxa with Cortinarius-like spores but characterized by basidiomata with a reduced stipe and a basally exposed hymenium with a loculate to lamellate gleba (Peintner et al., 2002). Singer and Smith considered this genus as representatives of Gastromycetes (Singer & Smith, 1958). Later, Moser (1964) and Horak and Moser (1965) observed that Thaxterogaster and Cortinarius are closely related and stated that Thaxterogaster is polyphyletic due to links between species or groups of species of Thaxterogaster and different subgenera of Cortinarius. ...
