One new species of the genus Coreomyces was collected on Micronecta sedula from the island of Java; C. javanicus sp. nov. is very similar to and apparently closely related to C. corixae. This species is characterized by a receptacle that is bent towards one side with cell I, nearly rounded. The length of cell I is equal to that of cell II and the perithecia are longitudinal, elliptical or cylin...

In previous studies investigating the genus Xanthoparmelia, thirteen different species have been reported from South Korea alone. However, there currently has been no revisional study performed until now. To explore the genus Xanthoparmelia, a phenotypic analysis was performed based on morphological, anatomical and chemical characters, while an investigation of Xanthoparmelia phylogeny was base...

The significance of sexual selection, the component of natural selection associated with variation in mating success, is well established for the evolution of animals and plants, but not for the evolution of fungi. Even though fungi do not have separate sexes, most filamentous fungi mate in a hermaphroditic fashion, with distinct sex roles, that is, investment in large gametes (female role) and...

Mushrooms are large reproductive structures of edible fungi belonging to either Ascomycotina or Basidiomycotina. They are non-green fungi which occur seasonally all over the world in various habitats. The mushrooms comprise a large heterogeneous group having various shapes, sizes and colours, all quite different in character, appearance and edibility. Of these large groups with more than 2000 e...

BACKGROUND Lytic polysaccharide monooxygenases (LPMOs) are a class of powerful oxidative enzymes that have revolutionized our understanding of lignocellulose degradation. Fungal LPMOs of the AA9 family target cellulose and hemicelluloses. AA9 LPMO-coding genes have been identified across a wide range of fungal saprotrophs (Ascomycotina, Basidiomycotina, etc.), but so far they have not been foun...

15 Living on emerged land raises several problems: water may be rare or absent, implying (1) that mineral nutrition is more or less impaired, (2) radiation (mainly toxic UV-rays) is not filtered out and (3) strong fluctuations of temperature are not prevented. In spite of those adversities, Precambrian land was colonized by phototrophic microorganisms, probably prokaryotes1, and multicellular t...

Mating crosses in all possible combinations between 15 monoascosporic isolates ofDidymella rabiei (Ascomycotina, Dothideales), derived from diseased chickpea stems collected at a single location in Genesee, Idaho, were prepared on sterile chickpea stem pieces incubated on moist sterile filter papers in glass petri dishes for 5-6 weeks at 10 C or in nylon mesh bags placed on the soil surface out...
