 328 ANNALS OF THE MISSOURI BOTANICAL GARDEN 



THELEPHORA 



Thelephora lutosa Schw. See Burt, Mo. Bot. Gard. Ann. 1: 

 21(). 1914. 



This rare species has been known only from the type collection 

 from Salem, North Carolina. There is now an additional gather- 

 ing by Dr. W. A. Murrill, 404, from Mountain Lake, Virginia, 

 July 8-14, of which a specimen is in the Mo. Bot. Gard. Herb. 

 The specimen grew in clay ground in mixed woods; a fragment of 

 buried rotten wood is attached to the short, radicated base. 

 This specimen does not necessitate any change in the description. 

 In the dried fructification the soft, fine pubescence of the upper 

 side, and cream color externally and within are distinctive char- 

 acters. The older portion of the hymenium has assumed a light 

 drab color with the spores, which are slightly colored, angular, 



4-6 X 4-4}/^ [L.

Fructifications effused, very thin, waxy, whitish in the her- 

 barium, somewhat perforate, the margin thinning out; in section 

 100-150 [X thick, with the hyphae about 3 [x in diameter, thin- 

 walled ; spores hyaline, even, fusiform, flexuous, 20-27 X 3-33^ [l, 

 often with a lateral branch. 



Covering as a cluster of small fructifications the terminal 

 portions of dead mosses on an area 2 cm. long, about 1 cm. wide. 



On wood in Europe, on dead mosses in Maine. 



T. calospora has fructifications rather more membranaceous 

 than those of our other species, and longer spores, which are 

 noteworthy by having frequently a branch stand out at right 

 angles from the body of the spore. I figured such a branched 

 spore in Mo. Bot. Gard. Ann. 6: 258. textf. 3. 1919.
