BURT THELEPHORACEAE OF NORTH AMERICA. XV 247 



Fructification^ broadly effused, thin, closely adnate, pale 

 pinkish buff to pale olive-buff in the herbarium, not shining, 

 hypochnoid, rimose-granular into areas or granules about 2-3 to 

 a mm., the margin thinning out, byssoid; in section 75-150 p. 

 thick, not colored, composed of erect, thin-walled, hyaline hyphae 

 23^-3 [t. in diameter, of irregular outline, collapsing, nodose- 

 septate; no gloeocystidia; spores hyaline, even, 3-5 X 2J^ (i, 

 copious. 



Fructifications 4-10 cm. long, 2-4 cm. wide. 



On decaying frondose wood. France and Vermont. May to 

 August. 



This species is related to Grandinia by its granular aspect but 

 the granules seem to have originated so largely from the cracking 

 of the fructification to the substratum that I concur in the in- 

 clusion in Corticium. It has a more hypochnoid surface than 

 C. scutellare. 



Specimens examined: 

 France: Allier, H. Bourdot, 16064, 16065. 

 Vermont: Middlebury, Battell Ledge, E. A. Burt. 



57. C. analogum (B. & G.) Burt, n. comb. 



Gloeocystidium analogum Bourdot & Galzin, Soc. Myc. Fr. Bui. 

 28:366. 1913. 



Type: authentic specimen in Burt Herb. 



Fructifications broadly effused, thick, adnate, fleshy-membra- 

 naceous, small pieces separable when moistened, becoming maize- 

 yellow to chamois in the herbarium, somewhat colliculose, not 

 cracked or but little cracked, not shining, the margin thinning 

 out; in section 500-1000 y. thick, colored like the hymenium, be- 

 coming zonate or somewhat stratose, composed of hyphae 3-4 (i 

 in diameter, densely interwoven, conglutinate and poorly defined, 

 of great numbers of imbedded spores and gloeocystidia; gloeo- 

 cystidia immersed in many zones or layers, 40-80 X 6-8 [x, be- 

 coming dissolved by potassium hydrate solution; imbedded 

 spores subglobose, 5-6 X 5 pi, minutely rough, slightly colored in 

 the deeper portions of the fructification, hyaline at the surface of 

 the hymenium; spores on basidia not demonstrated. 



Fructifications in fragments up to 8 cm. long, 3 cm. wide.
