^ -^CTDiuM ^scuLL— Hypophyllous, on pale yellowish, slightly 
Ihickened spots, 4-6""^ in diameter, ^cidia orange-yeiiow, 30-75 
on each spot, generally with a vacant space in the centre, hemi- 
spheric and closed at first, about 200/^ in diameter, at length opening 
above and becoming short cylindric, with an irregularly lacerated 
margin; spores orange-colored, irregularly globose (19-25/0 ^^^^'^ 
coarse granular contents; the component cells of the a^cidia subhex- 
agonal or oblong, and faintly striate, the striae extending more or less 
perfectly entirely across. 
On leaves of AlscuIus glabra. May. No. 526. 
^ciDiuM Verbentcola.— iEcidia hypophyllous, clustered, 3-35 
together, 200-250/^ in diameter, orange-red within, covered outside 
with a granular, semitransparent coat like grains of sugar; margin of 
aecidia white, recurved and sublacerate-dentate; component cells sub- 
hexagonal (19-25//), or elongated (30-35x20-25/^), surface marked 
with flexuous ridges and tubercles; spores globose, elongated or sub- 
angular by compression, 19-25//, orange. The corresponding spots 
on the upper surface of the leaves are at first pale yellow but become 
purplish black. . 
On leaves of Verbena uriicifolia (No. 532) and V.stricta (No. 549-) 
June. Possibly not distinct from ^c. Verbence, Speg., but differs witH 
constantly clustered cecidia with recurved margin, and in net being 
hemispheric at first.
