Abstract
Discharged teliospores of P. tumidipes were found in the vicinity of the telia on the lower surface of Lycium halimifolium. The pedicels were discovered to have a highly hygroscopic inner layer which swells greatly in water rupturing the outer wall and setting the spores free. Under certain conditions the pedicel reverses itself, completely surrounding the teliospore. The discharged spores are sticky, adhering to each other and to the leaf surface. This is the first report of teliospore discharge in the Uredinales.
