Trichoglossum 31 



equal, up to 6 cm. long, 2 3 mm. thick, densely velvety, com- 

 posed of a fascicle of parallel, brown hyphae, 5-8 n thick, looser 

 in the center, those at the surface projecting as short, septate 

 hairs, giving rise also to numerous acicular, black spines up to 

 225 ^t long; asci broadly clavate, apex narrowed, the pore blue 

 with iodine, reaching a length of 210-225 fi and a diameter of 

 20-22 n, 8-spored ; spores in a parallel fascicle in the ascus, 

 brown, cylindric-clavate, broadest above the middle, tapering 

 each way to the obtuse ends, 15-septate at maturity, 6-7 X 100- 

 160 M (120-150); paraphyses brown, cylindric, septate, usually 

 strongly curved, or coiled at the slightly thickened tips, 3 ^u 

 thick below, up to 8 /i thick above; hymenial spines numerous, 

 usually projecting about one-third their length beyond the hy- 

 menium, straight, acute, black, opaque, 8-10 /i thick, variable 

 in length. 



On rotten wood or on humus among leaves.

A capitate form of this species was received from Mr. Fred L. 

 Lewis which seemed almost distinct enough to be regarded as a 

 distinct species (Plate 78). However, since the ascophores are 

 very variable in form it is recorded simply as a capitate form of 

 the above species.

Ascophores clavate, or flattened, black, velvety with numer- 

 ous black cystidia, variable in size but often 2-3 cm. high; 

 ascigerous portion occupying one-third the entire length; asci 

 clavate-cylindric, reaching a length of 250-265 n and a diameter 

 of 20-25 ju, 8-spored; spores fasciculate, reaching a length of 105- 

 145 M and a diameter of 7 y., brown, clavate, broadest about the 

 middle, mostly 8-9-septate, rarely 5-6- or 7-septate, stout; pa- 

 raphyses cylindric, septate, pale-brown above, only slightly
