Abstract

Thirty collections of Loculoascomycetes from the Ajos-Bavispe National Forest Reserve and Wildlife Refuge, the Pinacate and Great Altar Desert Biosphere Reserve, and the Sierra of Alamos-Rio Cuchujaqui Biosphere Reserve, in Sonora, Mexico were studied. Ten new records for the Mexican mycobiota are presented: Capronia montana, Chaetoplea crossata, Didymosphaeria futilis, Glonium abbreviatum, Hysterographium mori, Montagnula infernalis, Patellaria atrata, Rhytidhysteron rufulum, Thyridaria macrostomoides, and Valsaria rubricosa. Photographs of macro- and microscopic characters are given for some species.

Abstract

Valsarin (3), 7-chloroemodin (5), emodin, and mannitol have been isolated from Valsaria rubricosa. There is mass spectral evidence also for the presence of three further compounds, probably 5,7-dichloroemodin (6) parietin (7), and 1,2,4,5-tetrahydroxy-7-methylanthraquinone (8). ‘Papulosin’ has been shown to be identical with valsarin.
