ritoMYCES 



containing no teleutosporea ; it appears probable that these belong to 

 U. Kabatianus, which will no doubt be found in many places, if lookedfor. 



Distribution: a few places in Europe and Asia Minor.

Urerfuxpores. Sori hypophyllous, radially arranged, occupy- 

 ing nearly the whole leaf-surface, rounded or elongated, often 

 confluent and com red by large fragments of the torn epidermis, 

 then pulverulent, orange, yellowish or even whitish ; spores 

 ellipsoid to oblong, faintly echinulate, orange or yellowish, 

 16—25 x 14—21 fi.

Teleutospores. Sori hypophyllous, scattered, rarely con- 

 tinent, minute, round, pulverulent, brown; spores globose to 

 obovoid or oblong, not thickened above, coarsely warted, brown, 

 26 — 40x20 — 30 ft: epispore 2 — 2 k fi thick; pedicels hyaline, 

 very deciduous, short or rather long; teleutospores are also 

 formed in the uredo-sori. 



On Alchemilla vulgaris. Common. Uredospores, April — 

 June; teleutospores, July — October. (Fig. 59.)
