Psilocybe makarorae : ウィキペディア英語版 | Psilocybe makarorae
''Psilocybe makarorae'' is a species of psilocybin mushroom in the family Strophariaceae. Officially described as new to science in 1995, it is known only from New Zealand, where it grows on rotting wood and twigs of southern beeches. The fruit body (mushroom) has a brownish cap with lighter coloured margins, measuring up to wide. The cap shape is either conical, bell-shaped, or flat depending on the age of the mushroom, and it features a prominent umbo. Although the whitish stem does not form a true ring, it retains remnants of the partial veil that covers and protects the gills of young fruit bodies. ''P. makarorae'' mushrooms can be distinguished from the similar North American species ''Psilocybe caerulipes'' by microscopic characteristics such as the presence of cystidia on the gill faces (pleurocystidia), and cheilocystidia (found on the gill edges) with more elongated necks. Based on the bluing reaction to injury, ''P. makarorae'' is presumed to contain the psychedelic compounds psilocybin and psilocin. ==Taxonomy== The species was first mentioned in the literature in 1981, when Pierre Margot and Roy Watling described a specimen collected in 1969 by Grace Marie Taylor near the Franz Josef Glacier as an unnamed ''Psilocybe'' with affinities to the North American species ''Psilocybe caerulipes''.〔 It was officially described as new to science in 1995 by mycologists Peter R. Johnston and Peter K. Buchanan.〔 In his 1996 book ''Psilocybin Mushrooms of the World'', Paul Stamets noted that the two authors are known to work with law-enforcement officials to assist in prosecuting those who illegally collect psychoactive mushrooms.〔Stamets (1996), pp. 126–7.〕 The type material was collected in 1990, near the Haast Pass crossing the Makarora River. The specific epithet ''makarorae'' refers to the type locality. ''P. makarorae'' is classified in Gastón Guzmán's section ''Mexicanae'' owing to the spore shape and bluing reaction upon injury. It is distinguished from other species in this section by the size of the caps, the presence of pleurocystidia, and the short-necked cheilocystidia.〔
