Resumen

LORENZO, Laura E  y  MESSUTI, María I. Additions and update to the knowledge of the genus Hysterographium (Ascomycota, Hysteriaceae) in southern South America. Darwiniana [online]. 2009, vol.47, n.2, pp.289-296. ISSN 0011-6793.

The present contribution is the second part of the taxonomic studies about the genus Hysterographium from South America. During the revision of Spegazzini´s type specimens, three valid species (H. andicola, H. australe and H. praeandinum), two doubtful species (H. cumingii and H. cuyanum), and one synonym of H. mori (H. bonaerense) were confirmed. Hysterographium subfuscum is not a valid species. Lectotypes for H. andicola and H. praeandinum were designated. A key to species of Hysterographium recorded from Argentina, Chile and Paraguay is presented.

Palabras clave : Argentina; Chile; Dothideomycetes; Hysterographium; Paraguay.
