Acervus
''Acervus'' is a genus of fungi in the family Pyronemataceae. They have cup-shaped fruitbodies that may be up to in diameter, with a bright yellow to orange-colored hymenium. Fruitbodies occur on soil, duff Duff may refer to: People * Duff (surname) * Duff (given name) * Duff (nickname) * Karen Duffy, an actress, model, and former MTV VJ once known as "Duff" * Duff Roman, on-air name of Canadian radio personality and executive David Mostoway (born ..., and plant debris.

Bessie Bernice Kanouse
Bessie Bernice Kanouse (born 1889; died February 4, 1969) was an American mycologist. Early life Kanouse was the daughter of Milton D. Kanouse (1856-1934) and Lillie L. Kanouse (1858-1914). She had at least two siblings, Laverne (1892-1895), who died young, and Leon (1894-1980). She graduated from Quincy High School in Quincy, Michigan in 1907 and went on to attend Michigan State Normal School in Ypsilanti. By 1913 she was working as a teacher in Quincy. In 1915 she was working as a laboratory assistant in the natural science department at Michigan State Normal and June 1916 is listed as her expected graduation date. Kanouse later returned to school and earned an AB at the University of Michigan (1922) and a PhD in biology (1926). Her interest in mycology was evident even in her undergraduate career; in 1920 she presented at the annual American Association for the Advancement of Science meeting in Chicago on "The Life History in Culture of a Homothallic Endogone".

Pyronemataceae
The Pyronemataceae are a family of fungi in the order Pezizales. It is the largest family of the Pezizales, encompassing 75 genera and approximately 500 species. Phylogenetic analyses does not support the prior classifications of this family, and suggest that the family is not monophyletic as it is currently circumscribed. Morphology Members of the family are diverse in ascomatal or cleistothecial form. Individual taxa may be sessile (without a stipe) to shortly stipitate, cupulate (cup-shaped), discoid (disc-shaped), pulvinate (cushion-shaped), or with turbinate (turban-shaped) epigeous apothecia. Also, taxa may be sub-hypogeous to hypogeous with closed, folded, or solid ascomata. Apothecia may range in size from less than 1 mm up to 12 cm in diameter, and may be brightly colored due to carotenoid pigments. Genera of the Pyronemataceae lack unifying macroscopic or microscopic characteristics; this lack of uniting characters has led various authors to propose a variety ...

Forest Floor
The forest floor, also called detritus, duff and the O horizon, is one of the most distinctive features of a forest ecosystem. It mainly consists of shed vegetative parts, such as leaves, branches, bark, and stems, existing in various stages of decomposition above the soil surface. Although principally composed of non-living organic material, the forest floor also teems with a wide variety of fauna and flora. It is one of the richest components of the ecosystem from the standpoint of biodiversity because of the large number of decomposers and predators present, mostly belonging to invertebrates, fungi, algae, bacteria, and archaea. Certain (adapted) plants may be more apparent in tropical forests, where rates of metabolism and species diversity are much higher than in colder climates. The major compartments for the storage of organic matter and nutrients within systems are the living vegetation, forest floor, and soil. The forest floor serves as a bridge between the a ...

Hymenium
The hymenium is the tissue layer on the hymenophore of a fungal fruiting body where the cells develop into basidia or asci, which produce spores. In some species all of the cells of the hymenium develop into basidia or asci, while in others some cells develop into sterile cells called cystidia ( basidiomycetes) or paraphyses ( ascomycetes). Cystidia are often important for microscopic identification. The subhymenium consists of the supportive hyphae from which the cells of the hymenium grow, beneath which is the hymenophoral trama, the hyphae that make up the mass of the hymenophore. The position of the hymenium is traditionally the first characteristic used in the classification and identification of mushrooms. Below are some examples of the diverse types which exist among the macroscopic Basidiomycota and Ascomycota. * In agarics, the hymenium is on the vertical faces of the gills. * In boletes and polypores, it is in a spongy mass of downward-pointing tubes. * In puffb ...

Apothecia
An ascocarp, or ascoma (), is the fruiting body ( sporocarp) of an ascomycete phylum fungus. It consists of very tightly interwoven hyphae and millions of embedded asci, each of which typically contains four to eight ascospores. Ascocarps are most commonly bowl-shaped (apothecia) but may take on a spherical or flask-like form that has a pore opening to release spores (perithecia) or no opening (cleistothecia). Classification The ascocarp is classified according to its placement (in ways not fundamental to the basic taxonomy). It is called ''epigeous'' if it grows above ground, as with the morels, while underground ascocarps, such as truffles, are termed ''hypogeous''. The structure enclosing the hymenium is divided into the types described below (apothecium, cleistothecium, etc.) and this character ''is'' important for the taxonomic classification of the fungus. Apothecia can be relatively large and fleshy, whereas the others are microscopic—about the size of flecks ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
