''Suillus collinitus'' is a pored mushroom of the genus ''Suillus'' in the family Suillaceae. It is an edible mushroom found in European pine forests. The mushroom has a reddish to chestnut-brown cap that reaches up to in diameter, and a yellow stem measuring up to tall by thick. On the underside of the cap are small angular pores, initially bright yellow before turning greenish-brown with age. A characteristic feature that helps to distinguish it from similar ''Suillus'' species, such as ''S. granulatus'', is the pinkish mycelia at the base of the stem. Molecular analysis has shown the species to be related to other typical Mediterranean ''Suillus'' species such as ''S. bellinii'', ''S. luteus'', and ''S. mediterraneensis''. ''S. collinitus'' is a mycorrhizal species, and forms associations with several species of pine, most notably the Aleppo pine. This tree species is commonly used in reforestation schemes and soil conservation against erosion in the Mediterranean region, and ''S. collinitus'' is often used as a beneficial inoculant to help the young trees better survive in typically harsh soil conditions. ==Taxonomy, phylogeny, and naming== |2= }} |2=''S. granulatus'' }} |2=''S. pungens'' }} |2= }} }} }} }} |caption=Phylogeny and relationships of ''S. collinitus'' and related species based on ITS sequences.〔 }} The species was first described as ''Boletus collinitus'' by Elias Magnus Fries in 1838.〔 Otto Kuntze transferred it to the genus ''Suillus'' in his 1898 ''Revisio Generum Plantarum''.〔 In 1969 Dutch mycologist H.S.C. Huijsman described the variety ''S. collinitus'' var. ''aureus'' (as ''S. fluryi'' var. ''aureus''; ''S. fluryi'' is a synonym of ''S. collinitus'')〔 based on a collection from Switzerland.〔 The variety ''velatipes'' was described in 1998 by Giampaolo Simonini and colleagues from Italian collections.〔 A 1996 molecular analysis of 38 different ''Suillus'' species used the sequences of their internal transcribed spacers to infer phylogenetic relationships and clarify the taxonomy of the genus. The results indicated that ''S. collinitus'' is most closely related to a specimen of ''S. granuatus'' collected from Nepal. According to the authors, this Nepalese isolate probably represents a species distinct from North American and European isolates, based on morphology and host tree association.〔 In 2006, a phylogenetic analysis of ''Suillus'' isolates collected from Spain showed that ''S. collinitus'' was closely related to other species "typical of the Mediterranean area", namely ''S. bellinii'', ''S. luteus'', and ''S. mediterraneensis''.〔 The specific epithet ''collinitus'' is derived from Latin, and means "smeared" or "greased".〔 The British botanist Mordecai Cubitt Cooke called the mushroom the "ringless yellow boletus" in an 1873 publication.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Suillus collinitus」の詳細全文を読む スポンサード リンク
