 round or nearly so, 0.2-0.5 mm. in diameter; peridium very 

 fragile and evanescent, frequently less conspicuous than the rup- 

 tured epidermis ; peridial cells irregularly cylindric, overlapping, 

 the outer wall sometimes tinted, about 3 \x thick, smooth, the inner 

 wall 3-4 \l thick, conspicuously verrucose ; aeciospores ellipsoid 

 or ovoid, 16-19 by 21-30^; wall light yellow, 1.5-2/* thick, closely 

 and noticeably verrucose.
