Lactarius subviscidus  Hesler & A.H. Smith (1979)                                    *Collections: Calfironia

Lactarius substriatus is a member of a group of difficult to tell apart bright red and peppery species in the PNW. The white milk that slowly turns yellow on exposure delimits it and the very similar Lactarius substriatus. This species has a slightly viscid cap only, which is uniformly colored and not striate on the margins.
