28 The North American Cup-Fungi 



seriate in the ascus, narrowly cylindric, straight, or curved, ends 

 obtuse, one end sometimes narrower than the other, contents 

 granular, at first continuous, then 7- finally 15-septate, 4-5 X 

 60-95 n, for a long time hyaline but ultimately becoming pale- 

 brown or fuliginous; paraphyses conspicuously brown above, 

 cylindric, septate, 3 n thick, the tips abruptly ellipsoid to globose 

 thickened, 6-8 ju thick and agglutinated together into a brown 

 epithecium. 



On very rotten wood and logs, in ravines and moist woods. 



Type locality: Canandaigua, New York. 



Distribution: New York and Idaho? 



Illustrations: Ann. Myc. 6: ^/. 8,f. 68-69; pi. 14, f. 145-148. 



8. Geoglossum pumilum Winter, Grevillea 15: 91. 1886. 



Ascophores very small, .5 2 cm. high, usually not exceeding 

 1 cm., slender, black; ascigerous portion distinct from the stem, 

 clavate-ellipsoid to oblong spherical, 1.5-3 mm. long, 1-2 mm. 

 thick when dry, rounded above; stem very slender, brownish- 

 black, squamulose, especially above, .5 mm. thick when dry; 

 asci clavate, stout, reaching a length of 185-200 jx and a 

 diameter of 20 to 27 yu. 8-spored; spores fasciculate in the ascus, 

 clavate-cylindric, tapering each way from above the middle, 15- 

 septate, 6 X 104-125 n (majority 110-115 /x long), deeply colored; 

 paraphyses longer than the asci, pale-brown above, nearly hya- 

 line below, the distal end stout, clavate, rather remotely septate, 

 usually nearly straight but sometimes strongly curved, inclined 

 to be constricted at the septa, 8-12 ^ thick. 



On soil. 



Type locality: Brazil. 



Distribution: Virginia, Bermuda and Porto Rico. 



Two minute fruiting bodies of this species were collected by 

 the writer in Bermuda (Britton, Brown & Seaver 1364) and two 

 in Porto Rico (Sci. Survey Porto Rico and the Virgin Islands 8: 

 74. 1926.). It will be noted that only two fruiting bodies of 

 this species were found at one time in Bermuda and in Porto 

 Rico. 



Doubtful and Excluded Species 



Geoglossum album A. E. Johnson, Bull. Minn. Acad. Nat. Sci. 1: 341. 

 1878; Mitrula Johnsonii Sacc. Syll. Fung. 8: 36. 1889; Microglossum album 

 Underw. Minn. Bot. Stud. Bui. 9: 495. 1896; Mitrula alba Massee, Ann. Bot. 

 11 : 284. 1897. This species was recorded from Minnesota but is exceedingly 

 doubtful. The name was changed by Saccardo to avoid making a homonym.
