24 ANNALS OF THE MISSOURI BOTANICAL GARDEN 



Type : in N. Y. State Mus. Herb., and part of type collection 



in Burt Herb. 



"Stem short, branching from near the base, the branches re- 

 peatedly and subpahnately branched, sometimes compressed, 

 tough, solid, reddish incarnate, whitish within, tips acute, whitish 

 or concolorous, the axils often rounded: taste acrid; mycelium 



hite: snores br 



of 



broad 



"Much decayed wood of coniferous trees. Floodwood. August. 

 It forms tufts 1.5-3 inches high and nearly as broad." 



When fresh the fructifications were between capucine-orange 

 and cinnamon buff and slowly acrid to the taste, they have be- 

 come pinkish buff in the herbarium and lost the acridity; spores 

 slightly colored under the microscope, minutely rough, 6-7 X 



4-4y 2 M- 



C. acris differs from C. stricta by the acrid taste and slightly 



smaller spores. 



27. C. tsugina Peck, N. Y. State Mus. Bui. 67: 27. 1903; Sacc. 

 Syll. Fung. 17: 196. 1905. Plate 5, fig. 31. 



Type: authentic specimen collected at Piseco, Adirondack 

 Mountains — probably the type — in N. Y. State Mus. Herb. 



"Stem very short, glabrous, branching from the base, solid, the 

 branches few or many, suberect, sometimes crowded, flexible, 

 rather tough, solid, terminating in acute tips; young plants and 

 growing tips creamy yellow, older parts and mature plants villa- 

 neous cinnamon or reddish brown; spores ochraceous, elliptic, 

 .0003 of an inch long, .00016 broad. 



"Plants 1-3 inches high, nearly as broad in the widest part. 

 Prostrate, decaying trunks of hemlock, Tsuga canadensis. Adi- 

 rondack mountains. July and August. Closely allied to C. 

 ablet i na, from which it differs in its naked stem, in having no 



bitter flavor and in wounds not assuming a green color." 



The hymenial portions are now cinnamon-brown and portions 

 of the trunk and axils cream-buff; spores slightly colored, mi- 

 nutely rough, 8-9x3-4 u. Peck did not record absence of acridity 

 for this species, but, unless not at all acrid, the species seems not 

 distinguishable from C. acris. 



28. C. cervicornis A. L. Smith, Linn. Soc. Bot. Jour. 35: 10. 

 1901 ; Sacc. Syll. Fung. 17: 194. 1905. 

 Type: probably in Herb, of Brit. Mus.
