BACKGROUND Mating-type loci of mushroom fungi contain master regulatory genes that control recognition between compatible nuclei, maintenance of compatible nuclei as heterokaryons, and fruiting body development. Regions near mating-type loci in fungi often show adapted recombination, facilitating the generation of novel mating types and reducing the production of self-compatible mating types. C...

(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’...

Abstract Four new genera encompassing six species are described in the Lyophyllaceae ( Agaricales ): monotypic Australocybe from Australia; Phaeotephrocybe Belize; Nigrocarnea Laos containing novel conidia-producing N. radicata and Praearthromyces two Asian taxa, P . corneri known Malaysia Singapore griseus Thailand, which lacks conidial production. In addition, we describe Arthromyces glabrice...

Upon channel bars or point bars within the lows of the Yellow River, a new sedimentary structure, named 'silt mushroom', has been observed. The process of their formation is interpreted to be via the ice process. The name, the silt mushroom comes from their figurative form. This is because they look somewhat similar to mushroom's in size and shape; being in the range of 1 to 10 cm in diameter, ...
