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.
