304 The North American Cup-Fungi 



with our species but no authentic material of Cenangium epi- 

 sphaeria Schw. has been seen. 



10. Cenangium tuberculiforme Kllis & Ev. Proc. Acad. Sci. 

 Phila. 1893: 452. 1893. 



Apothecia erumpent in dense clumps forming tubercular 

 masses up to 1 cm. in diameter, individual apothecia light- 

 yellow, furfuraceous-squamulose outside, irregularly cup-shaped 

 with the margin incurved, reaching a diameter of 2-3 mm.; 

 hymenium pale brick-red, contracted below into a short, stem- 

 like base; asci cylindric-clavate, reaching a length of 40-50 /x and 

 a diameter of 4-5 ji, 8-spored; spores obliquely 1-seriate, ellipsoid, 

 hyaline, with two small oil-drops, 2-2.5 X 5-6 ix\ paraphyses 

 filiform, branched, scarcely enlarged above. 



On dead twigs of Ilex glabra. 



Type locality: Newfield, New Jersey. 



Distribution: New Jersey and Massachusetts. 



ExsiccATi: Reliq. Farlow. 105. 



Excellent type material is in the herbarium at The New York 

 Botanical Garden. The only other specimen seen is the one 

 distributed by the Farlow Herbarium collected at East Billerica, 

 Massachusetts by J. B. Rorer. This is a very conspicuous and 

 interesting fungus. 



Doubtful and Excluded Species 



Many species of Cenangium have been reported from North America 

 with meager descriptions and in numerous cases based on sterile material. 

 Some of these are not ascomycetes at all. The names are recorded with the 

 hosts, hoping that future collectors may be able to tie them up with something 

 concrete. 



Cenangium aeruginosum Schw. Trans. Am. Phil. Soc. II. 4: 239. 1832. 

 On decorticated wood. Asci and spores unknown. 



Cenangium alboatrum Ellis & Ev. Bull. Torrey Club 24: 136. 1897. On 

 decorticated, decaying chestnut log. This does not appear to be a Cenangium; 

 material very poor. 



Cenangium alpinum Ellis & Ev. Bull. Torrey Club 24: 468. 1897. On 

 decorticated limbs of Abies. Spores described as allantoid, 2.5 X 10-14 m- 



Cenangium Andromedae (Schw.) Fries, Syst, Myc. 2: 182. 1822; Peziza 

 Andromedae Schw. Schr. Nat. Ges. Leipzig 1: 123. 1822. Asci and spores 

 unknown. 



Cenangium apertum Schw. Trans. Am. Phil. Soc. II. 4: 239. 1832. On 

 dead branches of Hydrangea. Nothing is known of this species. 



Cenangium asterinosporum Ellis & Ev. Bull. Torrey Club 10: 76. 1883. 

 Apothecia erumpent in cespitose cluster 2-3 mm. in diameter, individuals 

 .5-1 mm. in diameter; spores ellipsoid or subpyriform, subhyaline, constricted
