Daivis—Journey Through the Pacific Northwest. 779 
ing it from end to end and collected specimens of the follow¬ 
ing fungi: Sphaerotheca mors-uvae (Sehw.) B. & C. on the 
leaves (veins) and petioles of Ribes bracteosum and in small 
quantity on a single leaf of Leptaxis menziesfii; Septogloeum 
nuttalii Hark, on Osmaronia cerasiformis. This was very 
abundant in the upper part of the park and beyond. It re¬ 
minds one of Cylindrosporium padi Karst. On Spiraea arum 
cus occurred a CCrcospoxa having the following characters: 
Spots pale brown, indefinite, inconspicuous; hyphae hypophyl- 
lous, clustered, brown, 20-30 x 3-6 microns; conidia subclavate- 
cylindrical, 60-150 x 3-4 microns. This is perhaps to be re¬ 
ferred to Cercospora rubigo Cke. & Hark., with specimens 
of which it has not been compared. On leaves of Ranunculus 
greenei was a parasite of which these notes have been made: 
Spots round to oval or angular, yellow and indefinite becoming 
brown with age, white with the dense growth of hyphae and 
conidia beneath, 1-5 mm. in diameter; hyphae densely fascicu¬ 
late from a tubercular base, rather lax, hyaline, 25-40xl%-2l4 
microns; conidia fusiform, nucleolate, 12-16 x 3 microns. Mr. 
Shear informs me that this agrees with Ramularia aequivoca 
(Ces.) Sacc. as figured in pungi Italiani 9 Plate 994. There was 
found also Phragmidium rubi-idaei (Pers.) Wint. II and III 
on Rubus parviflorus; Septoria corylina Pk. on Corylus- calir 
fornica; Puccinia hydrophylli Pk. & Clint, on Hydrophyl- 
lum virginicum; Puccinia violate (Schum.) DC. II and III on 
Viola glabella; Gloeosporium ribis (Lib.) Mont. & Desm. on 
Ribes bracteosum , with sporules longer and narrower than usual 
(16-24 x 4-6 microns); Sphaerotheca humuti (DO). Burr, on 
Rubus ursinus; Puccinia asari Kze. on Asarum caudatum; 
Ovularia vancouveriae E. & E. on Vancouveria hexandra; 
Melampsoiii bigelowii Thurn. II on Salix flawescens; Micro- 
sphaera alni (Wallr.) Wint. on Vicia americana. On Ribes 
bracteasum was a fungus yielding the following notes: Spots 
reddish-brown above with a narrow dark border, paler be¬ 
neath, round or angular, 3-8 mm. in diameter, sometimes con¬ 
fluent; hyphae hypophyllous, sub-hyaline, continuous, straight 
or somewhat flexuose, forming minute gray or brownish-gray
