A large number of regional mycological floras, comprehensive monographic treatises, color atlas, reference books, checklists and popular field guides have dealt with fleshy pored mushrooms and related lamellate, sequestrate and corticioid taxa over the past two centuries (Fries, 1821(Fries, , 1838Frost, 1874;Quélet, 1888;Peck, 1889;Bataille, 1908;Smotlacha, 1912;Murrill, 1914;Coker and Couch, 1928;Coker and Beers, 1943;Singer, 1945Singer, , 1946Singer, , 1947Singer, , 1965Singer, , 1967Singer, , 1986Chiu, 1948Chiu, , 1957Heinemann, 1951;Imazeki, 1952;Digilio, 1957, 1964;Pilát, 1958;Hongo, 1960Hongo, , 1973McNabb, 1967McNabb, , 1968McNabb, , 1969Horak, 1968Horak, , 2011Corner, 1971aCorner, ,b, 1972bSnell and Dick, 1970;Smith and Thiers, 1971;Pilát and Dermek, 1974;Kühner, 1977;Vasiljeva, 1978;Tai, 1979;Wolfe, 1980;Pegler and Young, 1981;Moser, 1983;Singer et al., 1983Singer et al., , 1990Singer et al., , 1991Singer et al., , 1992Alessio, 1985;Garrido, 1988;Imazeki et al., 1988;Watling and Hollands, 1990;Turnbull, 1992, 1994;Both, 1993;Lakhanpal, 1996;Nagasawa, 1997;Watling and de Meijer, 1997;Ginns, 1998;Watling and Li, 1999;Bessette et al., 2000;Li and Song, 2000;Montecchi and Sarasini, 2000;Lannoy and Estadès, 2001;Ladurner and Simonini, 2003;Muñoz, 2005;Šutara, 2005Zang, 2006;Klofac, 2007;Ortiz-Santana et al., 2007;Knudsen and Taylor, 2008;Bernicchia and Gorjón, 2010;Zang et al., 2013;etc.), however, the approach to the study of bolete taxonomy has radically changed with the increasing availability of molecular genetic investigation applied to the study of basidiomycetes, casting doubts on the validity of relying solely on visible features for identification and highlighting the necessity to clarify the discrepancies between genetic and morphological criteria. ...
