Studies on Amanita (Amanitaceae) in Brazil: the discovery of A. aureofloccosa in the Brazil

“…Microscopic examinations were made from material mounted in 3 % KOH and Congo Red solutions. For the biometric values, the emended methodology of Tulloss and Lindgren (2005), slightly modified by Wartchow and Gamboa-Trujillo (2012), was as follows: w cs = breadth of central stratum of lamella; w st -near = distance from one side of central stratum to the nearest base of basidium; w st -far = distance from one side of central stratum to the most distant base of basidium on the same side of the central stratum; L, (W) = the range of average lengths (widths) of spores of each basidioma examined; L 0 , (W 0 ) = the average of all lengths (widths) of spores measured of all basidiomata; Q = the ratio of length to width of a spore or the range of such ratios for all spores measured; Q 0 = the average value of Q computed for one specimen examined and the range of such averages; Q m = average value of Q computed for all spores measured of all basidiomata; specific terms used for Amanita are summarized by Wartchow et al (2013a). Generic and infrageneric names and concepts follow Corner and Bas (1962) and Bas (1969), as modified by Yang (1997).…”

Amanita ahmadii, a new species of Amanita subgenus Amanitina section Validae from Pakistan

“…The genus Amanita consists of 95% of the species which are characterized by agaricoid basidiomata, colorless and hyaline, ballistosporic and smooth basidiospores, free lamellae, presence of volval remnants (Persoon 1797). A total of 540 known species of Amanita are distributed worldwide (Yang 2000, Kirk et al 2008, Menolli et al 2009, Tulloss 2009, Wartchow et al 2009, Justo et al 2010, Wartchow and Gamboa-Trujillo 2012, Cho et al 2015, Hosen et al 2015, Tang et al 2015, Wartchow and Cortez 2016, Jabeen et al 2017, Cui et al 2018, Kiran et al 2018a, b). From Pakistan, 19 species of Amanita are known to date (Ahmad et al 1997, Jabeen et al 2017, Kiran et al 2018a, b).…”
