Trypethelium virens. On the way back to Pine Brook a White Oak 

 was found harboring a large patch of Lecanora miculata near the 

 root. This species had been reported from North America by 

 Muhlenberg. It was described by Acharius in 1814. Tuckerman and 

 Fink both record the local material as doubtful, but authentic speci- 

 mens have been found in the southern states, and in Ohio. No 

 material properly belonging to this species, however, had been col- 

 lected in New Jersey or in any neighboring state. The writer's de- 

 termination has been confirmed by Dr. Albert W. Herre and Dr. 

 David H. Linder. 



Cold fingers making further collection impossible, what was 

 left of the party found a restaurant in Pine Brook where specimens 

 could be examined and discussed while waiting for an excellent 

 dinner of fried chicken, and the northbound train, stopped for us 



by the district superintendent in person. /- /- -kt

Trip of March 17 to Arden, N. Y. 



Despite a sleet storm the previous day, and a foot to two feet 

 of snow with an ice crust over the trails, four hardy souls went 

 collecting lichens of the Hudson Highlands along the trail past 

 Island Pond and over Hogencamp Mountain. On starting up the 

 road beside the elk range, two Physcias, the olive-brown Physcia 

 obscura and the slate gray Physcia trihacia were collected at the 

 base of a white oak. Cladonia delicata i. quercina and Cladonia 

 coniocraea f . ceratodes flourished on a stump which was projecting 

 through the snow. Up on top of the hill overlooking the Ramapo 

 valley the rock tripes, Gyrophora Dillenii and Umbilicaria pustulata 

 grow on the exposed rocks of the summit. 



At the outlet of Island Pond the sun had melted away the snow 

 in a few places to expose Cladonia papillaria f. molariforinis, 

 Cladonia caroliniana f . dilatata, Lecidea alhocaerulescens, and Par- 

 inelia coiupersa. On trees along the trail were seen several other 

 Parmelias including P. sulcata, P. saxatilis, P. olivacea, and P. con- 

 spur cata. 



The "Lichen trail" over Hogencamp Mountain goes through a 

 large colony of the "Iceland Moss," Cetraria islandica, discovered
