be sessile. In the field, the plants resemble those of Lachnea 

 hemispherica but are distinguished by the dark colored hy- 

 nienium and by the soft hairs instead of the sharp bristly ones 

 on the exterior. 



These specimens have been compared with those of Peziza 

 pubida in Ellis and Everhart's N. A. Fungi and found to be 

 the same. 



Peziza morgani Masse is referred to here for the reason that 

 the description given for this species in the "Journal of My- 

 cology " seems to conform in every particular to the material 

 described is Peziza pubida B. & C. in Ellis and Everhart's N. 

 A. Fungi, and to the same material collected here. The fusi- 

 form, warted, biguttulate spores given as a distinguishing 

 character for Peziza morgani Masse are found in Macropodia 

 pubida (B. & C.) Sacc, and it seems possible that the two 

 species may be identical. 



Genus X— O T I D E A Persoon.
