Lasiosphaeria setosa (Schw.). 



Sphceria setosa Schw., Syn. N. Am., 1,533. 



Perithecia gregarious, superficial, ovate- couical, about f mm. high 

 and h mm. broad, clothed except the black, entire or subsulcate, ob- 

 tuse ostiolum, with tuberculiform tufts of matted hairs among which 

 arise other, darker, longer hairs. Asci elongated, narrowed above, 

 short-stipitate, paraphysate, 8-spored, 100-120 x 12-15//. Sporidia 

 biseriate, cylindrical, hyaline, nucleate, curved near the lower end, 

 45-55 x 4-5/;.; about the same as in L. hirsuta. 



On rotten wood, Bethlehem, Pa. (Schw.). 



Lasiosphaeria emergens (Schw.). 



Sphceria emergens Schw., Syn. N. Am., 1,534. 



Mycelium of brown, branching threads septate and undulate, bear- 

 ing terminally (and laterally)? yellowish-brown, globose conidia 12- 

 15// diam. with coarsely granular contents. Sporidia nearly straight, 

 cylindrical, hyaline, 28-32 x 4//, apparently becoming 3-septate. 



Differs from L. Rhacodium in its ovate- conical perithecia. 



Chaetosphaeria squamulata (Schw.). 



Sphceria squama/a Schw., Syn. N. Am., 1,538. 



Melanomma squamulata E. & E., N. A. Pyr., p. 184. 



Sphceria squamata in Herb. Schw. 



Chcetosphceria squamulata Starbiick, Studier i Elias Fr. Svamp. Herb., p. 31. 



When the N. A. P. was published we had not seen an authentic 

 spec, of this species, which is accurately described by Starbiick, I.e., 

 the description there given applying perfectly to the spec, in Herb. 

 Schw. This spec, however, is labeled Sphceria "squamata" L. v. S., 

 instead of squamulata as given in Syn. N. Am. with the added note 

 "olim S. fuscospora." 



Herpotrichia diffusa (Schw.) var. rhbdomphala B. & C. 



Sphceria diffusa Schw., Syn. N. Am., 1,502. 



Splncria rhodomphala Berk. Hook., Lond. Journ. Bot., IV, p. 212. Sph. tris- 

 tis in Herb. Schw. 



Ampin 'sphceria subiculosa E. & E., Journ. Mycol., II, p. 103.

 Haudl., 1894. 



Didymotrichia diffusa Berlese, in the Proc. of the International Bot. Con- 

 gress, 1S92. 



The specc. distributed in Ell. & Evrht's N. A. F., 2,130, differ 

 from the Schweiuitzian spec, in having the perithecia smaller (about 

 f mm.), and less crowded, and in their rather smaller, less distinctly 

 constricted sporidia. These differences, however, seem hardly to be 

 of specific value, all the other characters being the same, and it seems
