7. Diaporthe exiguestroma sp. nov. 



Stromata minute, scattered, seated in the unaltered cortex, not 

 reaching the wood, no circumscribing line, circularly rupturing the 

 epidermis, mostly about .3 mm. in diameter. Perithecia one, two 

 or three in a stroma, white in cross-section, .1-2 mm. ; ostiola 

 when visible short, blunt. Asci comparatively few in a perithe- 

 cium 75-90 X 1 5 /a, paraphysate. Sporidia subbiseriate hyaline, 

 uniseptate, constricted, quadrinucleate, straight or slightly curved, 

 ends rounded, 18-24 X 6-7

8. Diaporthe oxyspora (Peck) Sacc. 



Valsa oxyspora Peck, Ann. Rep. N. Y. State Mus. 28 : 75. 1876. 

 Valsa ocularia Cooke & Ellis, Grevillea 6: II. 1877. 

 Diaporthe epimicta Ellis & Ev. N. Am. Pyrenom. 439. 1892. 



Comparison of the type of D. oxyspora (Peck) Sacc. with 

 specimens named respectively D. ocularia and D. epimicta by Mr. 

 Ellis and some recent collections leads to the conclusion that these 

 names are synonyms. Of my 1645 found on Ilex in 1890 which 

 Mr. Ellis first took to be a Diatrype, he later wrote that it was a 

 new species which he proposed to name from epimiktos — con- 

 fused — separating it from D. ocularia on account of the appendi- 

 culation of its sporidia. The appendages are not, however, con- 

 stant or persistent, for I have specimens from a single brush pile 

 of Ilex, showing them to be distinct or obscure or lacking. Prof. 

 Peck's type was reported " on oak limbs " but Dr. H. D. House 

 has found that the host material was Nemopanthes. 



9. Protoventuria vancouverensis sp. nov. 



Perithecia scattered, carbonous, thin, globose to conic, bristly, 

 120-150 {jl; bristles rigid, acuminate, pungent, 30-55 X 4-6 ju. at 

 base. Asci fusoid-cylindric, straight or curved, 45-55 X 14 

 paraphyses linear, longer than asci, not abundant. Sporidia 

 fuliginous, 2-3-seriate, uni-septate, bi- tri- or quadrinucleate, the 

 upper cell wider than the lower one and often containing one large 

 nucleus when the narrower, lower cell contains two, 14-15 X 

 4-5-5
