Teleutospores. Sori chiefly on the stems, compact, confluent, 

 forming blackish-brown masses, about h cm. long, encrusting at 

 intervals the flowering steins which are slightly thickened at 

 that spot, rarely on the leaves ; spores oblong to oblong-clavate,

rounded and not thickened above, slightly constricted, usually 

 somewhat tapering below, smooth, very dilute brown, almost 

 hyaline, 36 — 41 x 15 — 19 /x ; pedicels hyaline, rather stout, 

 persistent, about as long as the spore. 



On Sagina procumbens. Rare ; specimen in Herb. Phillips 

 (Brit. Mus.) from Ercal, near Wellington, under the name 

 Puce. Lyehnidearum. (Fig. 169.) 



The >spores of this species, as well as the character of the sori, render 

 it widely distinct from the various forms included under the name 

 P. Lyehnidearum ; the most obvious difference is in the total want of 

 thickening at the apex, unless this was due merely to the fact that all the 

 spores had germinated, which did not seem to be the case.
