Sori hypophyllous, on pallid irregular spots, numerous, aggregated in patches, or more generally spreading over nearly the whole of a leaf, more or less crowded on the nerves, minute, perfectly round, surrounded by the torn erect epidermis, pulverulent, reddish-brown; spores ellipsoid to.

Normal and abnormal teleutospores. ovate, rounded above with a small paler hemispherical pore- cap, slightly constricted, rounded below, smooth, yellow-brown, 27—45 x 15—24 fj,; pedicels thin, hyaline, deciduous, about as long as the spore; a few oval mesospores intermixed. On Betonica officinalis (Stachys Betonica). Not common. May—September. (Fig. 124.) The affected leaves are paler, narrower, and stand more erect than the healthy ones. Besides the mesospores, other anomalies are occasionally.
