48 Thirty-first Report on the /State Museum. 



Cenangium Cassandra Pk. 



Oblong or hysteriiform, erumpent, closely surrounded by the ruptured 

 epidermis, black ; asci oblong-clavate ; spores linear, curved, involved in 

 mucus, slightly colored, .0011'— .0012' long. 



Dead stems of leather leaf, Cassandra calyculaia. Center. June. 



Cenangium pezizoides Pk. 



Cups scattered, minute, erumpent, sessile or attached by a narrowed base, 

 smooth, black ; asci oblong-clavate ; spores crowded oblong-elliptical, .0008'- 

 .001' long, often containing a single large nucleus, sometimes slightly curved. 



Dead stems of leather leaf, Cassandra calyculata. Center. June. 

 This was associated with C. Cassandra, but the two are easily distin- 

 guished. 



Tympanis acerina Pk. 



Cups subcsespitose, obconic, erumpent, black with a distinct often flexuous 

 margin, disk concave ; asci oblong-cylindrical ; spores oblong, colored, .0005- 

 .0008/ long, containing a granular endochrome, at length quadrinucleate or 

 triseptate. 



Bark of maple trees. Adirondack and Catskill Mountains. Aug. and 

 Sept. 



The caps often manifest a tendency to form lines or grow in linear tufts. 

 They are usually accompanied by Sphceronema acerina, which is probably 

 one condition of the species. Both frequently grow from the same chink in 

 the bark. 



Patellaria olivacea Batsch. 



Decaying wood. Adirondack and Catskill Mountains. July and Sept. 

 A form of this species occurs which is hispid with straight rigid black hairs 

 or setae. 



Phacidium brunneolum Pk. 



Perithecia small, innate, brown or blackish-brown, with four or five rather 

 broad teeth ; disk dingy-white ; asci cylindrical or clavate, narrow ; spores 

 small, colorless, sublanceolate or oblong-ovate, often binucleate, .0003-.0004' 

 long. 



Fading leaves of Galium trifldum. Summit. Sept. 

 I have seen no description of Phacidium autumnale Fckl., but according 

 to my European specimens of that species, our plant is quite different. 



Triblidium morbidum Pk. 



Perithecia seated on a thin black crust, irregular, elliptical or oblong, 

 rugose, black, at length widely gaping or even suborbicular, revealing the 

 dingy-white or cinereous disk ; asci narrowly lanceolate, tapering towards 

 the base ; spores filiform, .003-.004' long. 



Decaying prostrate trunks of spruce. Sandlake. Aug. 



The general appearance of the perithecia is such as to suggest the idea 

 that they are diseased or badly developed. They indicate that the plant is a 

 Triblidium, but the spores are like those of Colpoma.
