BURT THELEPHORACEAE OF NORTH AMERICA. XI 259 



T. fusco-violacea is distinguished from the other species 

 hitherto found in North America by having slender and elon- 

 gated, rather than subglobose, spores. Bresadola described the 

 color of the fructification as fusco-violaceous when in vegetative 

 condition, drying lilacinus; I have seen dried specimens only, 

 and that from Bresadola is now pale smoke-gray. 



Specimens examined: 

 Sweden: Femsjo, L. Romell, J+18. 

 Tyrol: Cavalente, G. Bresadola. 

 New Hampshire: Crawford Notch, L. 0. Overholts, 4883 (in 



Mo. Bot. Gard. Herb., 56076). 

 Pennsylvania: Trexlertown, W. Herbst, 53. 



VELUTICEPS

Hymenium velvety with fascicles of colored, flexuous hyphae. 



The type species is Veluticeps Berkeleyi Cooke, which was 

 published originally as Hymenochaete veluticeps Berk. & Curtis. 



The fructifications are pileate in the species best known; 

 either dimidiate in our single Cuban species or sessile and 

 attached by the vertex in the species occurring on the opposite 

 side of the world in New South Wales. In both species the 

 fascicles of colored hyphae are 800 n or more long, about 40-60 n 

 in diameter, and traverse the whole or a large part of the fructi- 

 fication perpendicular to the surface of the hymenium, beyond 

 which they protrude up to 40-100 /x. The colored hyphae com- 

 posing the fascicles are about 4 /x in diameter, cylindric, some- 

 times granule-incrusted especially in the deeper portions of 

 the fructification and are closely crowded together, perhaps 

 20 or more to a fascicle; they have the character of the colored 

 cystidia, which are scattered between the basidia in the hyme- 

 nium of Stereum abietinum, S. glaucescens, and S. abnormis, 

 rather than of the conical, pointed setae characteristic of species 

 of Hymenochaete. The genera Mycobonia and Epithele are 

 closely related to Veluticeps by fascicles of hyphae protruding
