Abstract
Two new agaric species of Stropharia are described from Araucaria angustifolia (Brazilian pine) forests of southern Brazil. Stropharia agaricoides presents Agaricus-like basidiomes, small basidiospores (5–7 μm long) and pyriform cheilochrysocystidia. Stropharia venusta is characterized by the reddish to pinkish pileus, large basidiospores (12–15 μm long) and subclavate cheiloleptocystidia.
