Clitocybe Violaceifolia
''Clitocybe violaceifolia'', also known as the western cypress blewit, is a species of gilled mushroom native to western North America. ''C. violaceifolia'' can be distinguished from its choice-edible cousin, the wood blewit, by its association with trees in the cypress family. According to California mycologist Alan Rockefeller, ''C. violaceifolia'' "smells like mud". These mushrooms are theoretically edible but are reportedly quite unpalatable. This species was first described by William A. Murrill in 1913 from a type species collected near Salem, Oregon by Morton E. Peck. Murrill's description was " Pileus convex, somewhat gibbous, solitary, 3 cm. broad; surface slightly viscid when moist, smooth, glabrous, grayish-violet tinted with brown at the center, margin entire, slightly paler; lamellae very narrow, adnexed to slightly decurrent, rather crowded, arcuate, pale-violet; spores In biology, a spore is a unit of sexual (in fungi) or asexual reproduction that may b ...

Collybia Nuda
''Collybia nuda'', commonly known as the blewit or wood blewit and previously described as ''Lepista nuda'' and ''Clitocybe nuda'', is a species of fungi. Described by Pierre Bulliard in 1790, it was also known as ''Tricholoma nudum'' for many years. It was reassigned to the genus '' Collybia'' in 2023. The species is native to Europe and North America. It is found in both coniferous and deciduous woodlands. It has been cultivated in Britain, the Netherlands and France. It is a widely consumed edible mushroom. Taxonomy The French mycologist Jean Baptiste François Pierre Bulliard, Pierre Bulliard described the wood blewit in his work ''Herbier de la France'' in 1790 as ''Agaricus nudus'', reporting that it was common in the woods all year. He wrote of two varieties: one whose gills and cap are initially light violet and mature to burgundy, while the other has wine-coloured gills that intensify in colour with age. He added that the first variety was often confused with ''Cortina ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cypress Family
Cupressaceae or the cypress family is a family of conifers. The family includes 27–30 genera (17 monotypic), which include the junipers and redwoods, with about 130–140 species in total. They are monoecious, subdioecious or (rarely) dioecious trees and shrubs up to tall. The bark of mature trees is commonly orange- to red-brown and of stringy texture, often flaking or peeling in vertical strips, but smooth, scaly or hard and square-cracked in some species. The family reached its peak of diversity during the Mesozoic era. Description The leaves are arranged either spirally, in decussate pairs (opposite pairs, each pair at 90° to the previous pair) or in decussate whorls of three or four, depending on the genus. On young plants, the leaves are needle-like, becoming small and scale-like on mature plants of many genera; some genera and species retain needle-like leaves throughout their lives. Old leaves are mostly not shed individually, but in small sprays of foliage (cladop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alan Rockefeller
Alan Rockefeller (born 1980) is an American mycologist who specializes in Fungus, fungi photography, microscopy, DNA barcoding, and taxonomy. ''National Geographic'' described Rockefeller as "one of the most well-known mycologists studying psilocybe species", citing his memorization of Latin names and his "near-encyclopedic knowledge of mushrooms on the west coast of the U.S." Rockefeller, an expert in collection and classification of psilocybin and muscimol mushrooms, has used phylogenetic and microscopic analysis to identify several species not previously described. Rockefeller participates in several citizen science projects by identifying fungi on iNaturalist, Mushroom Observer, and Facebook, as well as teaching mushroom photography classes. Rockefeller's iNaturalist images are released under a Creative Commons license, allowing their use as photo illustrations for news articles and sites like Wikipedia. Rockefeller asserts that fungi photography is valuable not just for s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William A
William is a masculine given name of Germanic origin. It became popular in England after the Norman conquest in 1066,All Things William"Meaning & Origin of the Name"/ref> and remained so throughout the Middle Ages and into the modern era. It is sometimes abbreviated "Wm." Shortened familiar versions in English include Will or Wil, Wills, Willy, Willie, Bill, Billie, and Billy. A common Irish form is Liam. Scottish diminutives include Wull, Willie or Wullie (as in Oor Wullie). Female forms include Willa, Willemina, Wilma and Wilhelmina. Etymology William is related to the German given name ''Wilhelm''. Both ultimately descend from Proto-Germanic ''*Wiljahelmaz'', with a direct cognate also in the Old Norse name ''Vilhjalmr'' and a West Germanic borrowing into Medieval Latin ''Willelmus''. The Proto-Germanic name is a compound of *''wiljô'' "will, wish, desire" and *''helmaz'' "helm, helmet".Hanks, Hardcastle and Hodges, ''Oxford Dictionary of First Names'', Oxfor ...

Pileus (mycology)
In mycology (the branch of biology that includes the study of mushrooms and other fungi), the pileus is the cap or cap-like part of a basidiocarp or ascocarp ( fungal fruiting body) that supports a spore-bearing surface, the hymenium.Moore-Landecker, E: "Fundamentals of the Fungi", page 560. Prentice Hall, 1972. The hymenium ( hymenophore) may consist of lamellae, tubes, or teeth, on the underside of the pileus. A pileus is characteristic of agarics, boletes, some polypores, tooth fungi, and some ascomycetes. The word ''pileus'' comes from the Latin for a type of felt cap. Classification Pilei can be formed in various shapes, and the shapes can change over the course of the developmental cycle of a fungus. The most familiar pileus shape is hemispherical or ''convex.'' Convex pilei often continue to expand as they mature until they become flat. Many well-known species have a convex pileus, including the button mushroom, various ''Amanita'' species and boletes. Some, suc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lamella (mycology)
In mycology, a lamella (: lamellae), or gill, is a papery hymenophore rib under the cap of some mushroom species, most often agarics. The gills are used by the mushrooms as a means of spore dispersal, and are important for species identification. The attachment of the gills to the stem is classified based on the shape of the gills when viewed from the side, while color, crowding and the shape of individual gills can also be important features. Additionally, gills can have distinctive microscopic or macroscopic features. For instance, ''Lactarius'' species typically seep latex from their gills. It was originally believed that all gilled fungi were Agaricales, but as fungi were studied in more detail, some gilled species were demonstrated not to be. It is now clear that this is a case of convergent evolution (i.e. gill-like structures evolved separately) rather than being an anatomic feature that evolved only once. The apparent reason that various basidiomycetes have evolv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spore
In biology, a spore is a unit of sexual reproduction, sexual (in fungi) or asexual reproduction that may be adapted for biological dispersal, dispersal and for survival, often for extended periods of time, in unfavourable conditions. Spores form part of the Biological life cycle, life cycles of many plants, algae, fungus, fungi and protozoa. They were thought to have appeared as early as the mid-late Ordovician period as an adaptation of early land plants. Bacterial spores are not part of a sexual cycle, but are resistant structures used for survival under unfavourable conditions. Myxozoan spores release amoeboid infectious germs ("amoebulae") into their hosts for parasitic infection, but also reproduce within the hosts through the pairing of two nuclei within the plasmodium, which develops from the amoebula. In plants, spores are usually haploid and unicellular and are produced by meiosis in the sporangium of a diploid sporophyte. In some rare cases, a diploid spore is also p ...

Stipe (mycology)
In mycology, a stipe () is the stem or stalk-like feature supporting the cap of a mushroom. Like all tissues of the mushroom other than the hymenium, the stipe is composed of sterile hyphal tissue. In many instances, however, the fertile hymenium extends down the stipe some distance. Fungi that have stipes are said to be stipitate. The evolutionary benefit of a stipe is generally considered to be in mediating spore dispersal. An elevated mushroom will more easily release its spores into wind currents or onto passing animals. Nevertheless, many mushrooms do not have stipes, including cup fungi, puffballs, earthstars, some polypores, jelly fungi, ergots, and smuts. It is often the case that features of the stipe are required to make a positive identification of a mushroom. Such distinguishing characters include: # the texture of the stipe (fibrous, brittle, chalky, leathery, firm, etc.) # whether it has remains of a partial veil (such as an annulus (ring) or cortina) or ...

Fungi Of North America
A fungus (: fungi , , , or ; or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as one of the 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 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 organisms, named the ''Eumycota'' (''true fungi'' or ''Eum ...
