New Species of Bioluminescent Sect. (Agaricales, Mycenaceae) from Mexico.

section is macromorphologically distinguished by the collybioid or mycenoid basidiome, which is pink, purple, or violet, and, rarely, reddish-brown or yellowish. It is further characterized by the presence of oxalate crystals in the basal mycelium. The section comprises approximately 40 taxa, of which only five species and one variety exhibit bioluminescence.

Antigenotoxic Effect of Ascorbic Acid and Resveratrol in Erythrocytes of , and Human Lymphocytes Exposed to Glyphosate.

Glyphosate is a controversial herbicide. Its genotoxicity and presence in various ecosystems have been reported. The use of ascorbic acid and resveratrol could protect different organisms from glyphosate-induced genetic damage.

The - lineage: multilocus phylogenetic analysis and morphology confirm and in the Neotropics.

Many species of exhibit a high phenotypic plasticity. Hence, particularly among them, the morphological species concept remains difficult to apply, resulting in a currently confused taxonomy; as a consequence, the geographical distribution range of many species also remains very uncertain. One of the areas with a strong uncertainty, as far as morphological species concept is concerned, is the Neotropics.

A new stipitate species of Crepidotus from India and Thailand, with notes on other tropical species.

A new Asian species of Crepidotus (Basidiomycota, Agaricales), C. asiaticus, is presented based on morphological and nuc rDNA internal transcribed spacer (ITS1-5.8S-ITS2 = ITS) and large subunit (28S) sequence data.

Evaluation of genetic damage induced by glyphosate isopropylamine salt using Tradescantia bioassays.

Glyphosate is noted for being non-toxic in fishes, birds and mammals (including humans). Nevertheless, the degree of genotoxicity is seriously controversial. In this work, various concentrations of a glyphosate isopropylamine salt were tested using two methods of genotoxicity assaying, viz.
