Nothophaeocryptopus Gaeumannii
''Nothophaeocryptopus gaeumannii'' is a species of fungus that occurs as an endophyte inside the needles of Douglas fir, Douglas-fir trees. It is responsible for causing the nonlethal disease known as Swiss needle cast, which results in needle loss and reduction in growth in Douglas-fir. Traditionally, it has been considered part of family Venturiaceae, but molecular studies have confirmed its placement in Mycosphaerellaceae. Three different lineages of ''N. gaeumannii'' are known, each with distinct ecological, morphological, and molecular characteristics. Distribution This species of fungus is native to western North America. Remarkably, the disease’s name, Swiss needle cast, arises from the fact that the fungus was first discovered in Switzerland in the 1930s where it was found to be causing disease in plantations of Douglas-fir. It has since been introduced almost everywhere Douglas-fir is grown, and is now widespread in Europe, New Zealand, and Chile. Although the fu ...

Fungi
A fungus (: fungi , , , or ; or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and mold (fungus), molds, as well as the more familiar mushrooms. These organisms are classified as one of the kingdom (biology)#Six kingdoms (1998), traditional eukaryotic kingdoms, along with Animalia, Plantae, and either Protista or Protozoa and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of motility, mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
