Lactarius substriatus  A.H. Smith (1960)                                                        *Collection: 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 subviscidus. Lactarius substriatus additionally stands out with its viscid pileus and  yellow, translucently striate margin.
