Uredo salicorniae G. Cunn. 1930

Description

Uredosori amphigenous and on stems and bracts, scattered, bullate, 0.2-0.6 mm. diameter, ferruginous, pulverulent, partially covered by the ruptured epidermis. Spores elliptical, obovate or subglobose, 26-32 x 24-28 microns, average 29 x 25 microns; epispore chestnut brown, 2 microns thick, finely and closely echinulate; immixed with numerous, hyaline, cylindrical paraphyses.

Distribution

Endemic.

Notes

The host is an endemic species, not uncommon on the coast throughout (Cheesem., 1925, p. 410).
This may be the uredostage of Uromyces Salicorniae de Bary, the only rust recorded on this host genus, but as only uredospores are present on the specimens, ind as these do not altogether agree with the published descriptions of this species, our form has been provisionally named as new.

Typification

Pathogenicity

Rust has only been collected twice on this indigenous host [Salicornia australis], once at Lake Ellesmere in Canterbury and once on Rangitoto Island, Auckland.
