Description
Summary:Twelve species of Xylaria are cited as new records from Argentina: Xylaria adscendens, X. allantoidea, X. coccophora, X. cubensis, X. fissilis, X. gracillima, X. luxurians, X. melanura, X. multiplex, X. myosurus, X. kretschmarioidea and X. pseudoapiculata. The last two species are reported for the second time globally. We described for the first time the anamorphic or sterile stromata obtained in culture of X. kretschmarioidea, X. luxurians and X. melanura, and cultures in oatmeal-agar of X. pseudoapiculata. X. torulosa is synonymized under X. coccophora, and new substrates and hosts are reported for most species. Se describen doce especies del género Xylaria que se citan por primera vez para la Argentina: Xylaria adscendens, X. allantoidea, X. coccophora, X. cubensis, X. fissilis, X. gracillima, X. luxurians, X. melanura, X. multiplex, X. myosurus, X. kretschmarioidea y X. pseudoapiculata. El registro de las últimas dos especies es el segundo a nivel mundial. Se describen por primera vez los estromas anamórficos o estériles obtenidos en cultivo de X. kretschmarioidea, X. luxurians y X. melanura, y los cultivos en agar-avena de X. pseudoapiculata. Se sinominiza X. torulosa con X. coccophora, y se citan nuevos sustratos u hospedantes para la mayoría de las especies.
