1400122 southwestern white-spored gall rust Peridermium (An undescribed species) White-spored gall rust in the Toiyabe National Forest, Nevada. Previously thought to be a white-spored variation of Western gall rust, this fungus is probably actually a distinct species.
1400121 southwestern white-spored gall rust Peridermium (An undescribed species) White-spored gall rust on Ponderosa pine, Toiyabe National Forest, Nevada. Although previously thought to be a white-spored variation of western gall rust, this rust is probably a distinctly separate species. This photo was taken on a field trip in 1998. At that time the researchers who selected the site clearly explained that white-spored gall rust was distinctly different from typical orange-spored western gall rust, and that this was a site with the white-spored type. A species description and valid scientific name is still pending. Mycologia, 90(2), 1998, pp244-257. http://www.jstor.org/stable/3761300

1473047 southwestern white-spored gall rust Peridermium (An undescribed species) White spores, highly contagious local distribution, separation of outer bark gives galls a 'collared' feature; when photo taken it was recognized that this rust has white spores and resembles P. harnessii. DNA data suggests these rusts in SW should be recognized as distinct taxa but not yet formally described. A species description and valid scientific name is still pending.
