 and ao-ree with specimens of Ch. fusca, Fckl, in Saccardo's Myco-

 of Ch. phcBOstroma.

"Perithecia globose, seated on a rather thick, brown, pilose stra- 

 tum consisting of straight, acute threads. Sporidia oblong, obtuse at 

 each end, arcuate, 3-septate, 20 fi long. 



On roots of birch, New Jersey." 



We have not seen the original specimens described by Berkeley, 

 but specimens sent by Mr. Stevenson from Pennsylvania, and by Mr. 

 Commons from Delaware, and which seem undoubtedly to belong here, 

 have the perithecia densely gregarious, more or less pilose, with pale 

 brown, spreading hairs, seated on a dense, brown, pilose subiculum. 

 A.sci clavate-cylindrical, p. sp. 70-75x12-15 /z, with abundant par- 

 aphyses. Sporidia oblong-cylindrical, hyaline at first, becoming brown 

 and 3-septate, curved, 1 8-20 x 6-7 n, ends obtuse.

Perithecia small (100-200 fi), thickly scattered among the hairs 

 of the subiculum, and some of them, at least when young, sparingly 

 clothed with similar hairs, finally black and subshining, globose, scarceh^ 

 papillate, the ostiolum being so small as to be easily overlooked. Asci 

 clavate-cylindrical, 8-spored, briefly stipitate, paraphysate, 80 x 6^ ix. 

 Sporidia subbiseriate, oblong-fusoid, rather obtuse at each end, nearly 

 straight, 2-3-nucleolate, finally 2-septate, pale, 13 x4 /x. 



On decaying wood of Quercus, California (Harkness). 



The conidia (sec. Tul.) are borne in heads or spikes, at the tips of 

 the hairs of the subiculum, and are of three kinds; ovate, pale brown, 

 6^ x3 /x, others linear-cylindrical, 12 /x long, and still others subfusoid, 

 25-30 X 3 /z, 6-8-septate, olive-brown.
