where a delayed train gave me an hour to spend in a moist lo¬ 
cality on the edge of the city. The leaves of the aspen were 
here found to be spotted by a fungus which gave the follow¬ 
ing notes: Spots roundish angular, determinate, immarginate, 
dark brown above, much paler beneath, mostly 3-6 mm. in di¬ 
ameter; acervuli innate, about 75 microns in diameter; sporules 
straight or somewhat curved, 35-55 x 2-3 microns. On leaves 
of Populus tremuloides. FTorth Yakima, Washington, July 
8, 1905. At first I took this to be an undescribed Cylindro- 
sporvum f but on re-examination concluded that it is a Septoria 
in which the perithecia are not well developed and referred it 
to Septoria musiva Pk. 
Aecidium clematidis DO. was found on Clematis ligustici- 
folia ; ErysipKe polygoni DC. was abundant on Polyg¬ 
onum aviculare, as was Actinonema rosfxe (Lib.) Fr. on 
Rosa fendleriana. On Ribes tenuiflorum there was a Cer- 
cospora regarding which these notes were made: Spots 
wood-color, oval, determinate, 5-10 mm. in diameter, longer, 
paler and less angular than those of Cercospora ribicola 
E. & E.; hyphae tufted, amphigenous but more abundant be¬ 
neath, 20-35 x 3-5 microns; conidia 70-100 x 5-6 microns. To 
the description of Cercospora ribicola E. & E. is appended the 
statement, “well characterized by its red-brown spots and 
sphaeriaefonn tufts of hyphae,” well shown in Fungi Colum¬ 
biana 1714. As remarked above, the color of the spots is 
quite different in these specimens on Ribes tenuiflorum , while 
the hyphal tufts are of quite ordinary size. Mr. Shear in¬ 
forms me, however, that he finds specimens of Cercospora ri¬ 
bicola E. & E. in the herbarium at Washington that he does 
not think distinct from mine. Perhaps difference in host ac¬ 
counts for the difference in characters. 
ISTo further opportunities for collecting were found until 
Portland was reached, when I was introduced to Macleay 
park by Mr, GormaA. Macleay park is a canyon that has 
been preserved in its natural condition through the enterprise 
of the nature lovers of Portland and which reflects credit on 
their zeal and sagacity. After having made one or two short 
incursions, I spent half of my last day in Portland in ascend-
