Wavy Caps

Description:

Psilocybe cyanescens has a hygrophanous pileus that is caramel to chestnut-brown when moist, fading to pale buff or slightly yellowish when dried. Caps generally measure from 1.5–5 cm across, and are normally distinctly wavy in maturity.The color of the pileus is rarely found outside of P. cyanescens and closely related species, so it can be a useful identifying feature for the species complex. The cap, like most of the rest of the mushroom, can stain blue when touched or damaged. Lamellae adnate, light brown to dark purple brown in maturity, with lighter gill edges. The lamellae of P. cyanescens can bruise blue. There is no distinct annulus, but immature P. cyanescens specimens do have a cobwebby veil which may leave an annular zone in maturity.Both the odor and taste are farinaceous. P. cyanescens has smooth, elliptical spores which measure 9 - 12 x 5 - 8 µm.The type collection of the species from Kew Gardens featured no pleurocystidia, but North American collections are characterized by common clavate-mucronate pleurocystidia. Both European and North American specimens have cheilocystidia.Fresh Psilocybe cyanescens material generally bruises blueish or blue-green where damaged, and the staining remains visible after drying. This staining is most noticeable on the stem (which is white when undisturbed) but can also occur on other parts of the mushroom, including the gills, cap,and mycelium. This staining is due primarily to the oxidation of psilocin. (Psilocybin cannot be oxidized directly, but is quickly converted via enzymatic action to psilocin at injury sites which can then be oxidized, so even specimens with little psilocin still generally blue.)

Habitat:

Psilocybe cyanescens grows today primarily on wood chips, especially in and along the perimeter of mulched plant beds in urban areas, but can also grow on other lignin-rich substrates.P. cyanescens does not grow on substrate that is not lignin-rich.Fruitings have been reported in natural settings previously (although most appear to be migrations from mulched plant beds.) The species does not typically grow on mulch that is made from bark. In the United States, P. cyanescens occurs mainly in the Pacific Northwest, south to the San Francisco Bay Area. It can also be found in areas such as Western Europe, Central Europe, parts of Australia and parts of west Asia (Iran).The range in which P. cyanescens occurs is rapidly expanding, especially in areas where it is not native as the use of mulch to control weeds has been popularized. This rapid expansion of range may be due in part to the simple expedient of P. cyanescens mycelium having colonized the distribution network of woodchip suppliers and thus being distributed on a large scale with commercial mulch

Notes:

I found this mushrooom in my garden; in a damp area, Pruksachart Village,Eastern Bangkok.It's looked nice but inside they have a lots of poison if you eat it you may get sick! They were very small but they can kill animals that bigger than them!!!
