though others find then: habitually. I myself have always found para- 

 physes capitate, but not "stiff") in the uredo-sori. McAlpine records 

 three and even four-celled teleutospores in Australia, and I have found a 

 very few mesospores in the sori. 



Perhaps the easiest way to obtain the teleutospores is to search the 

 lower leaves of species of Poa, growing round leaves of Coltsfoot, as soon 

 as Eecidia of the second crop are perceived upon the latter towards the 

 end of .luly or headlining of August. 



DISTRIBUTION: Europe, Japan, North America, Australia.

Uredospores. Sori mostly epiphyllous, on linear brown spots. 

 scattered or in groups, often disposed in long linear series, 

 minute, elongated, reddish-brown; spores globose to obovate, 

 delicately verruculose, yellow, 18 — 25 /x ; paraphyses numerous, 

 clavate to capitate.

Teleutospores. Sori similar, but long covered by the epi- 

 dermis, blackish-brown: spores very irregular, ellipsoid or sub- 

 clavate or pyriform, obtuse or truncate and slightly thicken'' I 

 and undulated above, hardly constricted, somewhat attenuated 

 below, smooth, clear-brown, darker above, 25 — 40 x 15 — 25 /x; 

 pedicels none or very short, brownish, darker at base of spore 

 where the transverse wall is much thickened.
