hyaline and 3-3 ft in diam. A very curious species scut from Ohio. 

 under the above name. by Prof. A. P. Morgan.

H. armeniaca, B. &(. Grev. IV, p. 15. 



"Forming a thin, apricot-colored stratum which, when barren, 

 looks like Corticium ochroleucum, at length fertile. Perithecia super- 

 ficial, scattered, of a deeper tint." The sporidia (in Grev. XII, p. 78) 

 are said to be 4 p. diam. 



Specimens found at Newlield, N. J., on bark of dead Magnolia 

 glauca have been doubtfully referred to this species. The stroma is 

 of a rather loose, membranaceous-byssoid nature, thin and dull or 

 dirty-white, extending more or less continuously for several inches and 

 soon covered with a more or less compact layer of apricot-colored peri- 

 thecia which in drying shrink away from each other and leave the 

 hymenium more or less cracked. Asci cylindrical, about 75x4/,<. 

 containing 8 didymous, hyaline sporidia which separate into two sub- 

 globose or subovate cells 3-3 \ /JL in their longer diameter. 



H. ochroleiica, B. & Rav. Grev. 1. c. 



" Effused, thin, ochroleucous, seated on a pale mycelium, with a 

 barren border, often cracked when old. 7 ' The cells of the sporidia 

 are said by Cooke, in Grev. 1. c., to be 6 fj. diam., hyaline.

H. sciitelljeformis, B. & Rav. in Rav. Fungi Car., IV, No. 31. 



Stromata scutellate, centrally attached, margin free and, in the 

 larger specimens, undulate and sublobate, 1-2 mm. across, convex, 

 nearly smooth, only slightly punctate from the scarcely prominent 

 ostiola, color dull red. Cells of the sporidia subglobose, 3-4 [j. diam. 

 Our knowledge of this species is derived from the specimen cited, in 

 which the asci had disappeared, but the globose cells of the sporidia 

 \verc abundant.
