live mosses, dead stems and leaves of herbs, fallen twigs, branches 

 and bark of trees, etc. Two of the species recognized by Burt have 

 been reported from North Carolina by Curtis, and we are adding two 

 others. See Burt, Ann. Mo. Bot. Gard. 1: 358. 1914; Bourdot and 

 Galzin, Bull. Soc. Myc. Fr. 26: 223. 1910. 



Key to the Species 



On living mosses; saucer- or petal-shaped, up to 1 cm. broad. . .C. muscigena (1) 



On alder bark; small, cup-shaped, reddish-tawny C. fasciculata (2) 



On bark of red cedar; very small, whitish, cup-shaped, spores 



with a few long spines C. cupulaeformis (3) 



On dead stems of herbs; cup-shaped, whitish C. capula (4) 



1. Cyphella muscigena (Pers.) Fr.

This is the plant treated by me as Cantharellus retirugis (No. 

 3224) in an earlier paper (Journ. E. Mit. Sci. Soc. 35: 38. 1919). 

 Since then we have made three other collections of the plant, one 

 from the same spot a year later and two from other places. The two 

 last mentioned showed spores (from good spore prints) that averaged 

 longer than the two others, but otherwise there is no difference in the 

 plants. The basidia of all are small, club-shaped, rather abruptly 

 enlarged at the end, 7-7.5 \}^ thick, 4-spored. I cannot make out any 

 difference of importance between descriptions and illustrations of 

 Cantharellus retirugis and Cyphella muscigena. 



3224. See above. 



3931. On living moss (Ca//iarmMi), below Cobb's Terrace, January 8, 1920. Spores 



pip-shaped, 3-4.2 X 7-9.7;u. 

 4010. Same spot and one on same kind of moss as No. 3224. Spores the same, 



3.7-4.5 X 6-8.5ju. 

 4018. Near No. 3931, but on different moss, January 24, 1920. Spores 3-4.5 X 



7.5-9.7/.. 



2. Cyphella fasciculata (Schw.) B. & C. 



C fulva B. & Rav. 



Plate 30 



Cups gregarious in good numbers, and often in part densely fas- 

 cicled in groups or lines, about 0.6-3 mm. broad and same length, 

 attached in center by a short stalk about 0.3-0.8 mm. long; outer 

 surface of cup reddish-tawny, usually with one or two circular zones,
