leaf, short, soon deeply split and recurved; spores elliptical, 
epispore rather thick, densely tuberculate, 15-18 by 18-24 u; 
spermagonia numerous, uniformly scattered among the ecidia, 
honey-yellow. 
, Spots none; peridia abundant, generally {occupying all the lower 
surface of the leaf, rarely a few on the upper surface, short, margin 
crenulate; spores subglobose and subelliptical, brownish yellow when 
fresh, yellowish when dry, .0007-.0008 in. long—Peck, Am. Nat., Vol.

44. leucostictum, B. & C. 
Hypophyllous. Spots very small, scarcely evident, not 
discolored; secidia very small, irregularly clustered in little 
groups, short, border narrow, recurved and many times split; 
spores subglobose, minutely tuberculate, 11-12 by 12-16 p.

On Lespedeza procumbens: Johnson, May 11, 4616. 
This is named as above in Curtis’ Catalogue of the Plants 
of North Carolina, and described in Grevillea (III. p. 61) asa 
variety of 4. orobi, Pers. The specific distinction is preferred 
on account of the difference in size of scidia and spores as well 
as the appearance of the former. 
44. orobi, Pers. 
Hypophylous. Spots usually conspicuous, yellow, not 
thickened; zcidia scattered or collected in orderless groups, 
small or medium size, short, border many times split and re- 
curved; spores subglobose, usually somewhat angular, epispore 
rather thick, studded with low obtuse tubercles, often appear- 
‘ing smooth, 18-21 by 21-24 «; spermagonia few, mostly on the 
upper side of leaf, in the center of affected spots.

This is referred to the above named species with some 
doubt as to the identification. The ecidia are collected in 
more definite groups than are found in typical specimens of 
the species.
