Basidiomycetes and ascomycetes

Population biology studies, especially those done under field conditions or using simulated field conditions in the laboratory, are difficult due to the large number 

A variety of techniques have been used to estimate microbial biomass in natural habitats. Visual measurements of cell volume are laborious, and subject to a variety of errors when converted to dry-weight equivalents (Jones Mollison 1948 Carroll et al. 1980). Hydrolysis of fluorescein diacetate has been shown to be correlated to microbial biomass, especially for epiphytic fungi (Swisher Carroll 1980). Other methods of sampling include dilution plating of tissue homogenates or surface wash fluids, incubation of leaves or other biological

A mycorrhiza (literally, fungus-root) is a symbiotic association between a fungus and a plant. Mycorrhizae occur most frequently on plant roots, but may be found on any tissue involved in uptake of elements from soil. Mycorrhizae, formed by numerous fungi in the orders Phycomycetes, Basidiomycetes, and Ascomycetes, can be divided into two broad groups those that penetrate host cells (endomycorrhizae) and those that do not (ectomycorrhizae). A few fungal species defy this neat classification, penetrating the cells of one host but not those of another. 

Fungi can also be classified as lower (Phycomycetes) and higher (Basidiomycetes and Ascomycetes). Molds for which a sexual phase of reproduction has not yet been determined are called Deuteromycetes or Fungi Imperfecti. 

Toadstool (poisonous). Name for higher fungi from the group of basidiomycetes and ascomycetes that are toxic in both raw and cooked form. The toxins of the T. possess widely differing structures and activities. Thus, for example, the deadly amanita and the destroy-...

The fungi are generally sub-divided into four groups based on the structure of their sexual stages, although there is some controversy over the number. These are the Phycomycetes, Ascomycetes, Basidiomycetes, and Deuteromycetes (Fungi Imperfecti). 

The ability of yeast cells to liberate sphaeroplasts following treatment with (1-> 3)-/3-D-glucanases has been proposed as a taxonomic criterion for differentiating basidiomycetous from ascomycetous yeasts and for classifying the yeasts of the fungi imperfecti. ... 

Strain KMM 4500 of the species Stilbella aciculosa, harvested at a depth of 17 m in the Sea of Japan, owes its strong antibiotic activity to fusidic acid, a 4-methyl-sterol present in several species of Deuteromycetes, Ascomycetes and terrestrial Basidiomycetes, and discovered for the first time in a marine fungus (Kuznetsova et al, 2001).
