Psilocybe Caerulescens
''Psilocybe caerulescens'', also known as landslide mushroom ("derrumbe" in Spanish), is a psilocybin mushroom having psilocybin and psilocin as main active compounds. Along with ''Psilocybe mexicana'' and ''Psilocybe aztecorum'', it is one of the mushrooms likely to have been used by the Aztecs and is currently used by Mazatec shamans for its entheogenic properties. Description The taste and smell of ''Psilocybe caerulescens'' are strongly farinaceous, reminiscent of cucumber, though the smell lessens with age or when dry. Cap The cap is (1)3–7(10) cm broad. Convex to obtusely campanulate with an incurved margin at first, rarely becoming plane, and often are umbonate or with a slight depression in the center. It is viscid when moist from a separable gelatinous pellicle. The margin is slightly translucent-striate when moist. The cap is hygrophanous, yellowish brown to reddish brown with a silvery-blue metallic luster, paler at the margin, and drying to a beige ...

William Murrill
William Alphonso Murrill (October 13, 1869 – December 25, 1957) was an American mycologist, known for his contributions to the knowledge of the Agaricales and Polyporaceae. In 1904, he became the assistant Curator at the New York Botanical Garden (NYBG). He, along with the NYBG, founded the journal ''Mycologia'' and was its first editor for 16 years. Murrill was known to travel extensively to describe the mycota of Europe and the Americas. He traveled along the East Coast, Pacific Coast, Mexico and the Caribbean. Although Murrill was a very influential person at the NYBG, having worked his way up to become assistant director in 1908, his rather eccentric personality caused problems with his job. He went on annual collecting trips to Mexico, the Caribbean, Europe, and South America, sometimes, without informing any of his colleagues prior. These trips resulted in a cumulative total of 70,000 specimens, 1,400 of which are deposited in the NYBG.William Alphonso Murrill Records. ( ...

Hygrophanous
The adjective hygrophanous refers to the color change of mushroom tissue (especially the pileus surface) as it loses or absorbs water, which causes the pileipellis to become more transparent when wet and opaque when dry. When identifying hygrophanous species, one needs to be careful when matching colors to photographs or descriptions, as color can change dramatically soon after picking. Genera that are characterized by hygrophanous species include ''Agrocybe'', ''Psathyrella'', ''Psilocybe'', ''Panaeolus'', and ''Galerina''.

Annulus (mycology)
An annulus is the ring-like or collar-like structure sometimes found on the stipe of some species of mushrooms. The annulus represents the remnants of the partial veil, after it has ruptured to expose the gills or other spore-producing surface. It can also be called a ring which is what the Latin word annulus directly translates as. The modern usage of the Latin word originates from the early days of botany and mycology when species descriptions were only written in Latin. Outside of the formal setting of scientific publications which still have a Latin requirement, it will often just be referred to as a ring or stem ring in field guide A field guide is a book designed to help the reader identify wildlife (flora or fauna) or other objects of natural occurrence (e.g. rocks and minerals). It is generally designed to be brought into the "field" or local area where such objects exi ...s and on identification websites. Ring descriptions The way in which the structure and appea ...

Veil (botany)
A veil or velum, in mycology, is one of several structures in fungi, especially the thin membrane that covers the cap and stalk of an immature mushroom.
Encarta Dictionary Veils fall into two categories: * *
Universal veil In mycology, a universal veil is a temporary membranous tissue that fully envelops immature fruiting bodies of certain gilled mushrooms. The developing Caesar's mushroom (''Amanita caesarea''), for example, which may resemble a small white sphere ...

Mycelial Cord
Mycelial cords are linear aggregations of parallel-oriented hypha, hyphae. The mature cords are composed of wide, empty vessel hyphae surrounded by narrower sheathing hyphae. Cords may look similar to plant roots, and also frequently have similar functions; hence they are also called rhizomorphs (literally, "root-forms"). As well as growing underground or on the surface of trees and other plants, some fungi make mycelial cords which hang in the air from vegetation. Mycelial cords are capable of conducting nutrients over long distances. For instance, they can transfer nutrients to a developing fruiting body, or enable wood-rotting fungi to grow through soil from an established food base in search of new food sources. For parasitic fungi, they can help spread infection by growing from established clusters to uninfected parts. The cords of some wood-rotting fungi (like ''Serpula lacrymans'') may be capable of penetrating masonry. The mechanism of the cord formation is not yet precise ...

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 or cortina) or universal ve ...

Spore
In biology, a spore is a unit of sexual or asexual reproduction that may be adapted for dispersal and for survival, often for extended periods of time, in unfavourable conditions. Spores form part of the life cycles of many plants, algae, fungi and protozoa. 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. Under favourable conditions the spore can develop into a new organism using mitotic division, producing a multicellular gametophyte, which eventually goes on to produce gametes. Two gametes fuse to form a zygote which develops into a new s ...
