Numbers near the points correspond to the municipalities of (1) Boca da Mata, (2) Quebrangulo, (3) Igaci, (4) Limoeiro de Anadia and (5) Coruripe, state of Alagoas, and (6) Mucugê, state of Bahia, Brazil. Stars indicate type localities (with available morphological and molecular data) of Phyllopezus sp.1 (purple) and Phyllopezus sp.2 (green). Locations indicated with diamond denote samples of Werneck et al. (2012) not included in this study due to the absence of 16S rRNA data. Transparent white area [gray in the inset South America map in (A)] corresponds to Brazilian dryopen biomes. Inset map: South America.
