llYrsOTHECA sUBCORTiCALis, (C. & E.) Splmvonema suhcorticale, C. 

 & E., Grev. VI, p. 83.— Peritheciii subcylindrical, about U mm. high aud 

 100 thick, only slightly enlarged at base and containing a few sub- 

 globose, continuous, hvo\\n stylo pores. 8—5 r- diameter, or oblong- ovate, 

 6—10 X 4—5 ;^ and 2— 3-septate. xVscigerous cavity subapical, formed by 

 a gradual subovate enlargement 150— 175 //- diameter in the middle and 

 closely packed with the oblong-ovate or subelliptical, 8-spored asci, 12— 

 15 X 7—9 on slender pedicels 15—25 long, and without paraphyses. 

 The asci are hyaline aud smaller at first. Sporidia conglomerated, sub- 

 globose, brownish, 3— 3i 



Growing from the inner surface of the loosened bark or from the 

 exposed edges of loosened pieces of bark on dry, decaying oak limbs, 

 lying on the ground. Xewheld, N. J., Sept., 1877, and March, 1883. 



This description was made from re-examination of the original spec- 

 imens. 



Hy^psotheca calicioides, (Er.) Sporocyhe calicioides, Fi. S. M. Ill, 

 p. 342. Exsiccati, Eav. Eung. Car. I, No. 83.— Gregarious, subulate, 

 black and smooth, about li mm. high, 115 thick, the swollen, subellip- 

 tical, ascigerous cavity, about midway between the base and apex, 250 .'j- 

 thick. Asci (spore bearing part) oblong or obovate, 15—20 x 8—11 

 with a thread-like stipe of about the same length. Sporidia conglomer- 

 ated, elliptical, hyaline becoming brown, continuous, 6—7 x 3— 3i ,'J-. 

 Ravenel's specimens are on poplar bark. Mr. C. J. Sprague has sent 

 specimens collected by W. X. Suksdorf in \Yashington Territory, and 

 w^hich agree in all respects with Haveners specimens. Suksdorf 's speci- 

 mens are also, apparently, on bark of poplar. 



To the two above described we add the following new species which 

 has, as yet, been found but sparingly. 



Hypsotheca thujixa, E.&E.— On partly dead foliage of Cupres 

 sus t/iyoides, Xewfield, N. J., April, 1880. Perithecia subulate, 700—800 z^- 

 high and 55—60 thick below, with a gradually enlarged or swollen place 

 near the top, about 150 r- long and 90—100 thick and above this, again 

 contracted to about the same size as below, forming a truncate beak 75 — 

 80 fJ- long, the w^hole being, in fact, a hollow cylinder of fibrose-cellular 

 structure, slightly enlarged at bass and filled with minute, hyaline, 

 oblong or cylindrical, straight or slightly curved, 2 — 3 x i- fJ- spermatia 

 and the swollen part above filled with an abundance of club-shaped, 8- 

 spored asci, without paraphyses, and consisting of an obovate or subellip- 

 tical head or spore-bearing part 9 — 11 x 4i— 5i /J- and a filiform base or 

 stipe 15—20 fJ- long. The membrane of the asci is very delicate and 

 scarcely discernible after the sporidia have matured but easily seen in 

 the young state. Sporidia globose, pale-brown, 2i p- in diameter, collected 

 in a mass.
