1. Valsa clavigera Dearn. & Barth. 



Stromata cortical, removable with the bark and leaving no dis- 

 coloration on or in the subjacent wood ; thickly gregarious, or 

 subseriately arranged, pustulate, hemispheric, .75-1.5 mm., mostly 

 1 mm., in diam. Perithecia black, 5-15 mostly 8-1 1 in a stroma, 

 circinate immediately under the epidermis, globose, .3-4 mm., with 

 clavate ostiola .5-7 mm. long, 90 ^ across neck, 180 /x across head, 

 crowded, and usually obliterating the pale disk. Asci subglobose 

 to fusoid, 27-40 fjb. Sporidia conglobate to obliquely biseriate 

 allantoid, 9 X 2.5 ft. 



On dead branches of Schizonotus discolor (Ph.) Raf., Bremer- 

 ton, Wash., July, 1912. Bartholomew, 4/82. Type collection, 

 Fungi Columb. 5099. 



This is different from, although near V. opulifolia Peck, with 

 authentic specimens of which it has been compared. 



What appears to be this species (V . clavigera) on fire-killed 

 Acer macro phyllum Ph. in the same locality has larger stromata 

 with more numerous perithecia. This form is distributed in Fungi 

 Columb. 5098. 



2. Diatrypella minutispora sp. nov. 



Stromata scattered, gregarious, or seriate, small, mostly about 

 1 mm. at base, nearly superficial on the cortex, not blackening the 

 subjacent tissues, rupturing the epidermis into very narrow, often 

 elongate clefts. Perithecia black on a brownish, expanded, basal 

 stroma, .2 mm. but variable in size and shape, rough, shining 

 above, truncate-conic in the best developed examples, 3 to 5 in 

 a stroma; ostiola short, obtuse, perforate. Asci stipitate — stipe 

 sometimes half the total length, sp. p. obtuse- fusoid, 60-75 X 12/a;
