Hypoxylon ochraceotuberosum and Hypoxylon rickii (Ascomycota, Hypoxylaceae) in Las Yungas of Salta province, Northwest of Argentina

Abstract

Hypoxylon ochraceotuberosum and H. rickii are reported for the first time for the Argentinean funga based on recently collected specimens from the northwestern montane forest. Until now, H. ochraceotuberosum has only been known to occur in the Martinique (French West Indies). In contrast, H. rickii was already recorded for the Southern Cone, but based on specimens collected in the Atlantic Rain Forests from Southeast Brazil. Detailed descriptions and photo illustrations are provided for each species.
