Morchella snyderi : ウィキペディア英語版 | Morchella snyderi
''Morchella snyderi'' is a species of fungus in the family Morchellaceae. Described as new to science in 2012, it occurs in the non-burned montane forests of western North America, including California, Idaho, Montana, Oregon and Washington. It produces fruit bodies up to tall with ridged and pitted conical caps, and stipes that become pitted in maturity. The color of the morel is yellow to tan when young, but the cap ridges become brown to black in maturity or when dried. ==Taxonomy==
''Morchella snyderi'' was described as new to science in 2012, along with 13 other morels from the United States and Canada. The study, published in the journal ''Mycologia'', resulted from the Morel Data Collection Project, which aimed to help clarify the taxonomy, biology, and distribution of morel species in North America.〔 The specific epithet honors Leon C. Snyder, who described similar morels in Washington state in the 1930s.〔 According to Michael Kuo, who coauthored the species description, the morel should have been named ''Morchella crassistipa'', as it was previously described by Snyder in 1938, from collections made in Washington. However, molecular analysis determined that Snyder's type collection contained two distinct species, rendering the validity of the taxon dubious.〔 ''M. snyderi'' was also previously identified as phylogenetic species ''Mel''-12 (i.e., defined by DNA sequence) in a 2011 study.〔 Despite the light coloration of young fruit bodies, ''Morchella snyderi'' groups in the ''elata'' clade (named after the European black morel ''M. elata'') along with other "black" morels such as ''M. angusticeps'' and ''M. tomentosa''. Morphological characteristics of morels in this clade include pits on the cap that are usually elongated vertically in mature fruit bodies, and often the presence of a sinus (a space or indentation) where the cap attaches to the stipe.〔
