Illinois : Riverside, E, T. & 8. A, Harper, 851. 



Missouri: St. Louis, E, A, Burt (in Mo. Bot. Gard. Herb., 



54696). 

 Idaho: Priest Eiver, J. R. Weir, 83 y 548 (the latter in Mo. 



Bot. Gard. Herb., 17806) ; Avery, J. R. Weir, 393 (in Mo. 



Bot. Gard. Herb., 11982). 



4. C. Kalmiae (Peck) Burt, n. comb. 



Corticium Kalmiae Peck, N. Y. State Mus. Rept. 46 : 109. 

 1893; Sacc. Syll. Fung. 11 : 125. 1895. 



Type : in Coll. N. Y. State. 

 Fructification effused, thin, tender, 

 adnate, drying straw-yellow to tawny 

 olive, the subiculum and margin com- 

 posed of slender, whitish filaments; 

 hymenium glabrous, continuous ; 

 structure in section 150-300 /x thick, 

 composed of loosely interwoven, hya- 

 Fig. 4 line, non-incrusted hyphae mostly 



c. Kalmiae. 2-3 /i in diameter but with occasion- 



^Hi^ns^l^^x ?65.^ ''^''"''' ^lly ^ portion of a hypha swollen and 



4-7 n in diameter ; no cystidia ; spores 

 tawny olive in a spore collection, even, 9-12x6-7 /i. 



Fructification 3-4 cm. long, 2-3 cm. broad. 



On prostrate limbs and logs of frondose species, a single 

 collection on hemlock spruce. Vermont and New York. Sep- 

 tember and October. Rare. 



The type of this species is bright straw-yellow; the other 

 collections which I have referred here have similar structure 

 but are rather darker, approaching C. arida, from which, per- 

 haps, C, Kalmiae is not specifically distinct. The occasional 

 swollen portions of hyphae afford the best character for sep- 

 aration from C. arida. 



Specimens examined: 

 Vermont: Little Notch, near Bristol, E. A. Burt.
