Pityopus californicus (Eastwood) H. F. Copeland
Firstly described by Eastwood (1902) as Monotropa californicus, recombined to Hypopitys californicus by Heller (1913). Small (1914) described Pityopus oregona and noted Monotropa californicus from Eastwood as a synonym. The correct combination has been done by Copeland (1935). Distributed in California and Oregon, accepted by Wallace (1975).
