superficial mycelium, suggests the genus Peziza when examined 

 under a low power, but is a true Cyphella" 



I have examined superficially the type of Peziza tela B. <fe C. in 

 Farlow Herb, and the aspect is so similar to that of Solenia poriae- 

 formis that Massee's statement about the spores of P. tela being 

 colored should be confirmed. I was unable to make such exami- 

 nation of the spores. The type of Peziza Daedalea Schw. has the 

 same aspect as P. tela. 



C. Thaxteri Burt, n. sp. 



Type: in Burt Herb. 



Fructifications very small, gregarious, stipitate, cup-shaped 

 with the mouth open, drying between avellaneous and light 

 pinkish cinnamon, merely farinose under a lens but really hairy 

 when highly magnified, the margin inrolled when dry; hairs 

 Isabella color, even, flexuous, 25-30 X 4-43^ \l; hymenium Isa- 

 bella color; basidia simple, 16 X 4-6 ;jl; spores ochraceous, even, 

 7-8 X 5 [i; stem central, cylindric, with surface like the pileus. 



Fructifications about 34 Tarn, in diameter; stem about 140 ^ 

 long, 60-80 \l thick. 



On bark. West Indies. November. 



About 30 of the small, goblet-shaped fructifications are present 

 on an area about 3^ cm. long, 34 cm. wide. The farinose surface 

 of the exterior of the cups and stem is probably due to granular 

 matter on the hairs, but no trace of such matter is found when 

 the hairs are examined in permanent glycerine mounts by the 

 compound microscope. 



Specimens examined: 

 Grenada: Grand Etang, R. Thaxter, type, comm. by W. G. Farlow. 



HYPOCHNUS 



Hypochnus albus Burt, n. sp. 



Type: in Mo. Bot. Gard. Herb. 



Fructifications effused, small, circular, closely adnate, very 

 thin, snow-white, even, velutinous under a lens with the large 

 cystidia, not shining, the margin similar; in section 30-60 ix thick, 

 not colored, composed of loosely interwoven, hyaline hyphae 

 13^-2 (x in diameter, not nodose-septate, incrusted in the sub-
