wise, but do not accord exactly in spores. The Hawaiian specimens 

 have narrow, elliptical spores, mostly 12x32, some 12x28. The 

 Cuban spores are elliptical-oval, mostly 12x24, f ew 12x28. We do 

 not think it practical to separate them." 



SPECIMENS IN OUR COLLECTION. 



Cuba, F. S. Earle. 

 Hawaii, F. W. Terry. 



CYATHUS CANNA (Plate no). Cups campanulate, rigid, 7-8 

 x 6-8 mm., dark brown. Externally even, scabrous with short to- 

 inentum. Internally smooth, even, white as if covered with a thin 

 layer of whitewash. Peridioles covered on the upper side with a 

 silvery, thin tunica. Cortex double, the outer, thin, composed of small 

 fibrils. Spores small, globose, 7-9 mic. 



This plant grew in the earth, and is very similar to the preceding 

 in its cups, differing in its spores. It is close to microsporum, except- 

 ing habitat and the shape of the spores.

 Barbados, L. Lewton-Brain. 



CYATHUS MICROSPORUS (Fig. 19). Cups 7-8x6-7, even, 

 dark brown. Externally even with appressed hairs. Internally not 

 striate, even. (It surely does not belong in the section Eucyathus.) 

 Peridioles 1^/2-2 mm., with a thin tunica. Spores elliptical, very small, 

 4x6. 



The type specimens (Fig. 19, enlarged four times) were collected 

 on the Island of St. Domingue by Mr. Poiteau and grew caespitose on 

 rotten wood. Thev are now in Tulasne's herbarium at Paris.
