The measurement of the perithecia in Torr. Bull, is too large. 

 They are about J mm. cliam. This differs from Eutypdlu mtrrospom* 

 Cke., with specc. of which it has been carefully compared, in its smooth 

 ostiola and smaller perithecia, asci. and sporidia. Cal. tumidula. Sacc.. 

 also has the asci 40 //., and the sporidia 7-8 /JL Ions'. Tlie epidermis 

 is only slightly raised, and when stripped off, the perithecia mostly 

 come with it. 



Cal. herbicola, E. & E. (in Herb.) 



Perithecia scattered or 2-3 together, minute, about 100 a diam.. 

 covered at first by the cuticle, but when this disappears, superficial, 

 globose, black, with a short, spine-like, erect ostiolum. Asci wedge- 

 shaped, 18-20 x 5 //, truncate above. Paraphyses much longer than 

 the asci, stout and tapering, but evanescent. Sporidia biseriate. 

 oblong-elliptical, hyaline, continuous, 3-4xl|-2 p.

Perithecia subcuticular, circinate, 6-18 together, about \ mm. 

 diam., their cylindrical necks converging and erumpent in a small, 

 compact fascicle of short ostiola projecting but slightly, and mostly 

 4-sulcate. Asci clavate, 22-25 x 5 //, gradually attenuated to a slen- 

 der base; paraphyscs much longer than the asci. Sporidia minute, 

 3|x | [JL, curved into a semicircle.

Perithecia globose, often collapsing to concave, about | mm. diam., 

 lying on the surface of the inner bark in groups of 10-20, either 

 densely circinate or occasionally loosely aggregated, abruptly con- 

 tracted into decumbent, cylindrical necks converging to a central 

 point, with their obtusely rounded, smooth or obscurely radiate-sulcate 

 ostiola erumpent in a loose fascicle perforating the thick epidermic 

 but scarcely or only slightly rising above it. Asci cylindric-clavate. 

 Sporidia allantoid, 10-12 x 1 J-3 ;i, hyaline.

The specc. of this species in our Herbarium are unfortunately in 

 poor condition, sterile or old, asci entirely gone and only a few free
