Taxonomic studies of Amanita muscaria (L.) Lam (Amanitaceae, Agaricomycetes) and its infraspecific taxa in Brazil

“…As a continuation of studies on the genus Amanita conducted by our group (Wartchow & Maia 2007;Wartchow et al, , 2009Wartchow et al, , 2013, the present study raises the possibility of the occurrence of various distinct subspecies of A. muscaria in Brazil. We also address morphological studies, as well as discussing the importance of using morphological and ecological criteria in order to distinguish between subspecies.…”

Cantharellaceae of Guyana II: New species ofCraterellus, new South American distribution records forCantharellus guyanensisandCraterellus excelsus, and a key to the Neotropical taxa

“…1A, B). While evidence exists for broad geographic distributions of some ECM fungal species in the lowland South American tropics (Wartchow and Maia 2007, Menolli et al 2009, Henkel et al 2011, Uehling et al 2012, Wartchow 2012, C. guyanensis constitutes the first case of an individual species being documented over a geographical area circumscribing nearly the entire Guiana Shield region, with a N-S distribution of , 1200 km, and E-W of , 2500 km. Consideration of the de Meijer specimen from Parana in southern Brazil would extend the known distribution of C. guyanensis a further 3000+ km southward.…”

“…ex Miq.) Ducke (Sapotaceae) (Singer et al 1983), as also noted in Singer's personal communication to RH Petersen included with the specimen housed at TENN. Until recently C. guyanensis was one of the few valid Cantharellus species known from the lowland South American tropics (Wartchow et al 2012a, Wilson et al 2012). Three new Brazilian species have since come to light that deserve comparison with C. guyanensis.…”
