Spots numerous, irregular, scattered, dark-brown, 1-5 mm., 

 mostly in indefinite areas that become orange or reddish and 

 often extending over the whole leaf. Acervuli amphigenous but 

 mostly epiphyllous, nearly concolorous, the larger ones with a

 subarcuate, 30-45 X S~7 !*-> mostly 2-septate. 



On living leaves of Schizonotus discolor (Pursh) Raf. Van- 

 couver Island, August, 191 6, John Macoun 969. 

 This may be only a variety of the preceding species. 



38. Septogloeum Salicis-Fendlerianae Dearn. & Barth. sp. nov. 



The spots are somewhat arid, subcircular areas, 2-4 mm., 

 bounded by an unbordered, raised line, more distinct on the 

 upper side of the leaf. Acervuli amphigenous but mostly epiphyl- 

 lous, pycnidia-like in the younger stages but developing into 

 circular, yellowish-hyaline depressions, 100-150/x. Sporules 

 hyaline, grumous, curved, mostly i-septate, 15-50 X 3 -5-6 

 mostly about 45 X 5 



On living leaves of Salix Fendleriana Anders., Caldwell, Idaho, 

 Sept., 1 91 2, E. Bartholomew, 4968. Type collection, Fungi Co- 

 lumb. 5085. Many of the leaves in this collection bear numerous 

 brown, angular spots which mark the areas occupied by the Sep- 

 togloeum. 



Fungi Columb. 2779 an d 4387 are this species. It is quite 

 distinct from Septogloeum salicinum (Peck) Sacc. ; indeed it 

 comes nearer Cylindrosporium salicinum (Peck) Dearn. 



39. Cylindrosporium Artemisiae Dearn. & Barth. sp. nov. 



Spots brown, angular, following the veins, becoming confluent, 

 indistinctly visible through the tomentum on the lower side of 

 the leaf. Acervuli numerous, epiphyllous, concolorous, 60-90 ju. 

 Sporules hyaline, subclavate, subflexuous, 1-5-septate, 20-50 X 

 3-4 A*. 



On living leaves of Artemisia Suksdorfii, Piper, Pleasant Beach,
