15 or subangular or otherwise irregular.
“III. Mostly hypophyllous and arranged in a ring around the clusters
of aecidia, but also more or less scattered and forming groups unaccompanied
by aecidia or extending down on the petiole of the leaf; sori subhemi-
spherical, lead-color, about one-half millim. in diam., opening above in a
circumscissile manner, with a distinct round opening, as if the top had been
cut away, and discharging through this opening the abundant reddish-brown
spores after the manner of a Blelnnconium; spores elliptical, scarcely con-
stricted, minutely granular-roughened, mostly rounded at both ends, scarcely
thickened at the apex, 22~30xlfi-20//. On very short pedicels.” J. B. Ellis
