180 PUCCINIA 
Uredospores. Sori hypophyllous, minute, scattered or 
circinate, roundish, soon naked, brown; spores subglobose to 
ovoid, echinulate, pallid-brown, 
20—23 x 16—19 », with three 
~ germ-pores. 
Teleutospores. Sori similar, 
y but long covered by the grey 
epidermis, often confluent, or 
; . standing in circles round the

Teleutospores and mesospore. ecidia or uredo-sori, blackish- 
brown; spores ovoid or oblong, 
rounded at both ends, hardly thickened above but with a 
broad colourless papilla on each germ-pore, gently constricted, 
smooth, pallid-brown, 22—30 x 15—18 uw; pedicels hyaline, 
short, deciduous; an occasional mesospore was seen. 
On Primula acaulis (vulgaris). Not common. Aicidia in 
May; teleutospores, June—October. (Fig. 129.) 
All three spore-forms may be found on the same leaf. The teleuto- 
spores are rather irregular in shape ; mesospores are not infrequent, and 
Fischer describes and figures three-celled spores. This parasite is recorded 
on the continent also on Primula elatior and P. veris. 
DISTRIBUTION: Central Europe.
