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 |

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.
