NOVITATES OCCIDENTALES. 147 
Spots terminal or marginal, rusty brown, with a narrow, 
reddish border, sometimes none, the entire leaf being dead 
and dry. Prithecia amphigenous, subglobose, perforated 
above, 150 to 200 u diam., semierumpent but loosely covered 
by the upraised edges of the ruptured and whitened epider- 
mis. Sporules oblong, hyaline, continuous, 6 to 8 x 24 
to 3 u. 
Closely allied to Ph. Quercus, Saccardo, but in that 
species (sec. specc. in Rab. F. Eur. 2896) the spots are obic- 
ular and paler, with a narrow raised margin, and the peri- 
thecia slighly prominent are closely covered by the epider- 
mis which is not ruptured. The sporules are about the same 
in both. The Calif. specimens are accompanied by Pesta- 
lozzia Monochaeta, Desm. on the same leaves. 
Cercospora Hanseni, E. & E. 
On leaves of Asclepias ecornuta, Kell., at J ackson, Ama- 
dor Co., Calif., Coll. Geo. Hansen, com. Marshall A. Howe. 
Amphigenous tufts thickly scattered over dark, dull brown 
spots 3 to 4 mm. diam., and also more extensively over adja- 
cent green parts of the leaf. Hyphex short (10 to 15 x 5 to 
6 w), simple, olivaceous, obtuse, continuous, often thickened 
at the apex, arising from a small globose stromatic base. 
Conidia cylindrical, olivaceous, 1-to 4-septate, 30 to 50 x 4 
to 5 y, ends obtuse.

Streptanthus suffrutescens. Allied to S. tortwosus but 
perennial and suffrutescent, the stout caudex-like very leafy 
trunk 6 or 8 inches high, this parting into several flowering 
branches 1 or 2 feet long; whole herbage glabrous, light- 
green, very glaucous: cauline leaves 2 inches long, cuneate- 
obovate tapering to a somewhat winged petiole, the leaf- 
margin coarsely and not deeply serrate-toothed, the apex
