Lactarius alnicola
''Lactarius alnicola'', commonly known as the golden milkcap, is a species of fungus in the Russulaceae family. The fruit bodies produced by the fungus are characterized by a sticky, vanilla-colored cap up to wide with a mixture of yellow tones arranged in faint concentric bands. The stem is up to long and has yellow-brown spots. When it is cut or injured, the mushroom oozes a white latex, which has an intensely peppery taste. The acrid taste of the fruit bodies renders them unpalatable. The fungus is found in the western United States and Mexico, where it grows in mycorrhizal associations with various coniferous trees species, such as spruce, pine and fir, and deciduous species such as oak and alder. It has also been collected in India. Two varieties have been named: var. ''pitkinensis'', known from Colorado, and var. ''pungens'', from Michigan.
==Taxonomy==
The species was originally described by American mycologist Alexander H. Smith in 1960, from a collection made near Warm Lake, Idaho, two years prior. The species was originally collected under alders with conifers nearby, and its specific epithet reflects the presumed association between the species〔—''alnicola'' means "living with alder".〔 Researchers subsequently discovered that the species has a relationship with conifers, not with alders, as the name implies.〔Bessette ''et al''., 2009, pp. 145–46.〕 The mushroom is commonly known as the "golden milkcap".〔
''Lactarius alnicola'' is classified in subsection ''Scrobiculati'' of section ''Piperites'' in the genus ''Lactarius''. Species in this subsection are characterized by having a milk-white to creamy or whey-like latex that soon turns yellow upon exposure to air, and which may stain freshly cut surfaces of the fruit body yellow. Further, the cap margin is bearded, strigose (covered with sharp, straight, and stiff hairs), and coarsely tomentose or woolly when young. Other species in the subsection include ''L. subpaludosus'', ''L. delicatus'', ''L. torminosus'', ''L. payettensis'', ''L. gossypinus'', ''L. pubescens'', ''L. resimus'' and ''L. scrobiculatus'' (the type species of the subsection).〔Hesler and Smith, 1979, p. 237; pp. 285–86.〕
