Extension of Range of Gladonia floridana 



The following paragraph was contained in a letter from Mr. 

 Raymond IT. Torrey dated December 9, 1937: 



"A curious example of how little is known about some plant ranges, is 

 shown by a discovery I made, along the path described, to the . Ice Caves 

 east of EUenville, N. Y., of great quantities of Cladonia floridana. This 

 lichen was first found in Florida, about 100 years ago and named floridana, 

 for that reason. Older lichenists accepted that supposed hmitation of range. 

 But within the past ten years, with wider collecting by students of the genus, 

 it has been found along the coastal plain, in Maryland, southern New Jersey, 

 Long Island, and about Buzzard's Bay, Mass. But C. M. Robbins, in a paper 

 on the species, in Rhodora, a few years ago, described it as a "coastal plain 

 plant." Yet we now have it from the Shawangunks, at 2,200 feet ! Suggests 

 some analogy with the presence of Corema Cotiradii, otherwise a coastal plain 

 plant, on Gertrude's Nose, about 1500 feet."

Gladonia alpestris Near Lake Shehawken 



Cladonia alpestris is rare enough in the Torrey area to warrant 

 notice. A single small biscuit about three inches in diameter was 

 found in Scott Township, about one mile north of Lake Shehawken, 

 Wayne County, Pa. The determination has been confirmed by Dr. 

 Evans who reports that it is the only specimen in his collection 

 between the New York area and one in West Virginia. It grows on 

 an open hilltop at an elevation of 2100 feet. 



At Lake Shehawken I have also found an extensive colony of 

 Cetraria islandica. Its average height here is about two inches. It is 

 in an old unploughed pasture in light shade and open field, facing 

 south-east, and at an elevation of 1850 feet.
