ing botanical and geological features have been in the Park, 

 by the marking of a new trail. 



Up to the discovery of this colony, in September 1933, by 

 the writer, the only known occurrence of Cetraria islandica in 

 the Harriman Park was a stand of not more than twenty small 

 plants on the Appalachian Trail on Fingerboard Mountain, 

 west of Lake Tiorati found by Mrs. G. P. Anderson a few years 

 ago. The lichen occurs in large olive brown clumps, along the 

 edges of the broad, ice-smoothed ledges of the ridge, which, 

 structurally is an extension of Surebridge Mountain, but is 

 topographically a part of the Hogencamp Mountain — Ship 

 Rocks — Black Rocks mass, so that it may be identified as on 

 Hogencamp Mountain. 



The region is interesting botanically and preserves in a large 

 degree the original plant associations: it was part of the estate 

 assembled by the late Edward H. Harriman, before he died, 

 after which his widow gave the area to the Interstate Park. 

 Mr. Harriman cared for it and protected it from fire during his 

 life and the Park has done the same since. 



Old and extensive colonies of earth and rock lichens are 

 usually evidence of long freedom from ground fires, and such 

 is the case on this new trail and on the Ramapo-Dunderberg 

 Trail. The wide granite ledges are bordered by dense mats of 

 Cladonia rangiferina, C. uncialis, C. chorophaea, ff. simplex and 

 carpophora, and standing out sharply among these gray-green 

 lichens are the brown clumps of Cetraria islandica. There is 

 plenty of it on the trail and more probably on other ledges seen 

 in the woods to the southeast. 



Other lichens on this trail are Stereocaulon paschale, on 

 ledges and boulders, some of the latter covered with it; Cladonia 

 cristatella,ff. vestita and Beuvoisii; Lecanora tartarea and cinerea; 

 Lecidea russelli, on limestone glacial boulders brought from the 

 north ; Gyrophora Dillenii and Umbilicaria pustulata (one small 

 thallus found on living wood of an oak tree, unusual for this 

 rock-loving lichen); on trees: Cetraria atlantica, and Oakesiana; 

 Evernia furfuracea, var. olivetorina, on pitch pine, the first I 

 have seen in the Harriman Park, although it occurs on Schune- 

 munk, Kittatinny and Shawangunk Mountains. 



Several large and well fruited colonies of Baeomyces roseus, 

 evidently just starting to raise and expand their pretty pink-
