SIR, Esteban B; PERERA, Teresa C; ROMERO, Andrea I  e  HLADKI, Adriana I. Novedades para el género Rosellinia (Ascomycota-Xylariaceae) en el noroeste de la República Argentina. Bol. Soc. Argent. Bot. [online]. 2012, vol.47, n.3-4, pp.311-321. ISSN 1851-2372.

Novelties for the genus Rosellinia (Ascomycota-Xylariaceae) from Northwest of Argentina. Rosellinia canzacotoana is reported for the first time in the southern Cone of America and Rosellinia arcuata is a new record from Argentina. Rosellinia necatrix is reported growing on a native host of the Argentine flora. Three Spegazzini's holotypes: Rosellinia australis, Rosellinia bonaerensis and Rosellinia smilacina were studied and their taxonomic and nomenclatural positions are discussed. A dichotomous key to rosellinoid taxa so far known from Northwest Argentina and distributions maps is presented.
