Coordinator notes: Yes, I have the article and Robert Michael Pyle and I have collected together in California and southeast Arizona. Personally, I have encountered nominate mariposa and cascadia, the latter at North Umqua Creek, Oregon-Ken Davenport. The nominate is local in the Tioga Pass area near Yosemite in Hudsonian Zone forest.
