Conocybe apala (Fr.: Fr.) Arnolds, Helvella solitaria P. Karst. and Hygrocybe miniata (Fr.) P. Kumm.; three new mushrooms from India

The himanimides, new bioactive compounds from Serpula himantoides (Fr.) Karst.

In a screening of basidiomycete cultures from Chile for the production of antibiotics we identified a Serpula himantoides strain as a producer of metabolites inhibiting the growth of bacteria and fungi. Bioactivity guided purification resulted in the isolation of four new antibiotics. Their structures were elucidated by spectroscopic methods. All four compounds are succinimide and maleimide der...

(Species of Hypholoma (Fr.) P. Kumm. (Strophariaceae, Agaricales) in Rio Grande do Sul State, Brazil). Detailed descriptions, illustrations, discussions and a key for identification of the known species of the genus Hypholoma (Fr.) P. Kumm. in Rio Grande do Sul state are presented, as well as a revision of the Hypholoma specimens deposited in the Fungi Rickiani collection. Based on the authors’...

Free radical scavenging activity of antitumour polysaccharide fractions isolated from Ganoderma lucidum (Fr.) P. Karst

The study was conducted to investigate the free radical scavenging activities of polysaccharide fractions extracted from the fruiting body of medicinal mushroom, Ganoderma lucidum (Fr.) P. Karst (Reishi) using different antioxidant capacity assays. Four intracellular polysaccharide fractions were obtained by the hot-water extraction and precipitation with ethanol, by ammonium oxalate extraction...

Antibiotics from basidiomycetes. X. Scorodonin, a new antibacterial and antifungal metabolite from Marasmius scorodonius (Fr.) Fr.

Scorodonin (1), a novel biologically active metabolite, was isolated from submerged cultures of the mushroom Marasmius scorodonius (FR.) FR. Its structure has been determined by chemical and physical methods. The antibiotic inhibits the growth of bacteria, yeasts, and filamentous fungi. In cells of the ascitic form of EHRLICH carcinoma the incorporation of thymidine and uridine into DNA and RNA...
