Fig. 169. P. Saginae. Teleutospores, from the Ercal specimen. 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 Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Grove, W.
