280 PUCCINIA 
though others find them 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 ecidia of the second crop are perceived upon the latter towards the 
end of July or beginning of August.

Uredospores. Sori mostly epiphyllous, on hnear 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 ~; paraphyses numerous, 
clavate to capitate.

Teleutospores. Sori similar, but long covered by the epi- 
dermis, blackish-brown ; spéres very irregular, ellipsoid or sub- 
clavate or pyriform, obtuse or truncate and slightly thickened 
and undulated above, hardly constricted, somewhat attenuated 
below, smooth, clear-brown, darker above, 25—40 x 15—25 p; 
pedicels none or very short, brownish, darker at base of spore 
where the transverse wall is much thickened.
