hyaline and 3-3 1 /i in diam. A very curious species sent from Ohio, 

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

 Parasitic on Cyathus utriatus, HofF. 



H. armeniaca, B. & C. Grev. IV, p. 1 5. 



"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 // diam. 



Specimens found at Newfield, N. J., on Ijark 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 drpng shrink away from each other and leave the 

 h}Tiienium more or less cracked. Asci cylindrical, about 75 x4 fi, 

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

 globose or subovate cells 3-3 1 n 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." The cells of the sporidia 

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



On Myrica cerifera, Carolina (Ravenel). 



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



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

 larger specimens, undulate and subloliate, 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 fi 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 

 were abundant. 



On bark of Acer ruhrum, Carolina (Ravenel). 



H. patella, C. & P. 29th Rep. N. Y. State Mus. p. 57. 



"Fleshy, patellate, discoid, 1-2 lines broad, pale ochraceous. 

 Asci cylindrical. Sporidia globose, sixteen, hyaline, 3-4 // diam. Re- 

 sembles, externally, some species of Helotium." 



On decaying wood. New York (Peck). 



H. minima, Sacc. & Ell. Mich. II, p. 570. 



Stromata scattered, superficial, pulvinate, discoid, olivaceous, be- 

 coming nearly black when dry, hardly 1 mm. in diam., minutely punct-
