Lactarius subflammeus

Lactarius subflammeus, commonly known as the orange milk cap, is a North American milkcap mushroom in the family Russulaceae. The slimy to sticky fruiting bodies have scarlet caps that soon fade to bright orange; the typically longer-than-wide orange stipe contrasts with whitish gills. When cut it exudes white, acrid latex, and it is considered inedible. Described in 1979 by Lexemuel Ray Hesler and Alexander H. Smith, it belongs to Lactarius sect. Russularia and fruits in late summer to autumn as an ectomycorrhizal associate of conifer forests, especially in the Pacific Northwest; NatureServe currently assigns no global status rank. It was described from coastal sand dunes at Pacific City, Oregon, after having been confused in the literature with Lactarius aurantiacus. Microscopically, it has a white spore print and hyaline, amyloid spores ornamented with isolated warts and short, non-reticulate ridges, a combination that helps separate it from similar orange species such as Lactarius ......read more on Wikipedia.
