laginous. The rela tionships of the genus may be seen by compari- 

 son with the following genera: Clitocyhe has a fleshy stipe; 

 Collybia has an incurved margin; Omphalia has decurrent gills; 

 Marasmius has a tough reviving cap; Galactropus has a milky 

 juice. 



The generic name Prunulus has been adopted to include most 

 of the species formerly classified under the genus Mycena. 

 Fifty North American species of this genus have heretofore been 

 described. Fifty-five new species have been found and will be 

 described in a forthcoming part of the North American Flora. 



Dr. Roland M. Harper followed with a paper on "An Inter- 

 esting Fern Locality in Florida Threatened with Destruction." 

 The following abstract was furnished by the speaker: 



"In the southeastern corner of Citrus County, Florida, there 

 is a small area of limestone cliffs and grottoes where ten or 

 twelve species of ferns grow on a single acre. They are mostly 

 tropical species or near relatives thereof, and most of them are 

 not known elsewhere within many miles. The rocks afford a 

 treacherous footing and some accidents have occurred there, at 

 least one of them fatal. The locality was visited by Curtiss in 

 1881, Donnell Smith in 1883, Underwood in 1891 and the speaker 

 in 1 91 5. A limestone quarry has recently been opened nearby 

 and the destruction of the vegetation seems to be imminent." 



Dr. George E. Stone, of the Agricultural College of Massa- 

 chusetts, spoke of the nature of the work at the Station, and the 

 great interest in the subject of shade-tree planting throughout 

 the State. 



Di. N. L. Biitton spoke of the new journal Addisonia founded 

 by the Addison Brown fund and published by the New York 

 Botanical Garden. This journal will be issued quarterly. 



Dr. Britton exhibited an interesting specimen of Carex Fraseri, 



now in blossom at the New York Botanical Garden. 



Adjournment followed.
