其他摘要：In a survey of the agaricoid fungi from the western region of Paraná State, south Brazil, 2 species of Copelandia were identified. Copelandia cyanescens is a common and widely distributed coprophilous species with typical bluing reaction. Copelandia mexicana is a rare and poorly known mushroom, lignicolous and not conspicuously bluing, with distinctive macro- and micromorphological features. This is a new record from South America. Both species are described and illustrated in detail, and discussed regarding distribution, taxonomy and nomenclature.
