68 MEMOIRS OF THE NEW YORK BOTANICAL GARDEN 



Rhizomorpha molinaris Pers. 



In the Mammoth Dome, on old timbers. A very peculiarly 

 modified species, some specimens being many-branched, others 

 cylindrical, and often ten inches in length. A large mass of 

 these plants on being accidentally shaken exhibited brilliant 

 phosphoresence. 



Cyathus vernicosus (Bull.) DC. 



A "bird's nest" fungus common on old timbers in the Mam- 

 moth Dome has been identified as being this cosmopolitan form. 

 It appears to be a poorly developed visitor from the outer 

 \vorld. 



MUCOR MUCEDO L. ^ 



Growing abundantly and sometimes covering areas of thirty 

 square feet and hanging in great festoons at the Steeps of 

 Time, River Hall, and on the timbers around the Bottomless Pit. 



MiCROASCUS LONGIROSTRIS Zukal. 



On rejectamenta in Washington Hall and also in Audubon 

 Avenue. 

 Zasmidium cellare Fr. 



At the top of the Corkscrew, in the Main Cave, on the head 

 of an old barrel, which it entirely covered with a dense brown 

 coating. Probably introduced from without, with the host. 

 Gymnoascus setosus Eidam. 



On sticks, bread, etc., in Washington Hall. This locality is the 

 Cave's dining room. 

 Sporotrichum densum Link. 

 Sporotrichum flavissimum Link. 



Both species occurred on dead beetles {Anophthalmus) in 

 Washington Hall. 

 Laboulbenia subterranea Thaxter. 



Found only on dead Anophthalmi, particularly in the neigh- 

 borliood of Annette's Dome. 

 Laboulijenia sp. 



Numerous specimens on the dung of bats in Audubon Ave. 

 and Rafinesque Hall. 



COEMANSIA sp. 



Papulospora sp. 



BOUDIERA Sp. 



The paucity of material precludes any si)erific reference of 

 these three forms.
