182 The North American Cup-Fungi 



7. Gorgoniceps jamaicensis Seaver, Mycologia 38: 552. 1946. 



Apothecia gregarious, or crowded, occasionally several coa- 

 lescing, sessile or nearly so, becoming patellate, in dried speci- 

 mens pale yellowish-amber, semitranslucent, reaching a diameter 

 of .5 mm.; hymenium plane, or slightly concave; asci clavate, 8- 

 spored, reaching a length of 140 ^ and a diameter of 20 n, taper- 

 ing below into a short, stem-like base; spores fasciculate, cylindric 

 with the ends attenuated, reaching a length of 50-55 ix and a 

 diameter of 9-10 /x, becoming 7-septate; paraphyses filiform, 

 about 2 ju in diameter. 



On bamboo, Bambusa vulgaris. 



Type collected by W. A. and Edna Murrill in Chester Vale, 

 Jamaica, December 21-24, 1908, altitude 3000-4000 ft. (No. 311). 



This seems to differ from our Bermuda species in the much 

 larger spores and asci. 



Doubtful Species 



Gorgoniceps dinemasporioides (Ellis & Ev.) Sacc. Syll. Fung. 8: 506. 1889; 

 Peziza dinemasporioides Ellis & Ev. Jour. Myc. 1: 42. 1885. This was de- 

 scribed as a Peziza by Ellis and placed in the genus Gorgoniceps by Saccardo 

 because of the filiform spores. The spores are not filiform but fusoid and the 

 asci appear to be borne in thin-walled perithecia, clothed with long Chaetomi- 

 «w-like hairs. In the opinion of the author this is not a cup-fungus at all. 



31. POCILLUM DeNot. Comm. Critt. Ital. 1: 361. 1864. 



Apothecia stipitate, or substipitate, cup-shaped, or expanded; 

 asci clavate-cylindric, 8-spored; spores filiform, hyaline. 



Type species, Helotium Cesatii Mont. 



This genus is close to Gorgoniceps apparently differing only in 

 the stipitate, or substipitate character of the apothecia which 

 ordinarily is not considered a very reliable one. So far as ob- 

 served only one species has been reported within our range. 



1. Pocillum hypophyllum (Berk. & Curt.) Sacc. Syll. Fung. 8: 

 606. 1889. 



Peziza hypophylla Berk. & Curt.; Berk. Jour. Linn. Soc. 10: 369. 1868. 



Apothecia hypophyllous, short-stipitate, externally brown, 

 crateriform, the margin sinuate; hymenium livid; spores filiform. 



On the under side of some leaf among the brown, velvety 

 down. 



Type locality: Cuba. 



Distribution: Known only from the type locality.
