Sori hypophyllous, occasionally on the petiles, scattered, minute, rarely confluent, pul- verulent, cinnamon; spores ellipsoid to obovate, thickened (up to 7 /a) above and echinulate in the upper part only, pale-brownish, 24—36 x 17—26/z, with three germ-pores. Teleutospores. Sori similar, but blackish-brown, on the stems and petioles often larger and long covered by the grey epidermis; spores ovate or ovate- oblong or even clavate, rounded at both ends or attenuated below, not thickened at the apex but with a small papilla or pore-cap, hardly constricted, nearly or quite smooth, pale-brown, 30—48 x 20—28 /x; pedicels hyaline, short, deciduous. On Conium maculatum. Not common; England, Wales, Ireland (Clare Island). August, September. (Fig. 144.) Distinguished by the uredospores, which are echinulate only in the upper half ; the spines gradually diminish in size downwards and the lower half is quite smooth. The teleutospores which I have examined are quite smooth when empty, even under the highest power, but the protoplasm is very granular and presents a misleading effect at first Fig. 114. P. Conii.
