Field Trip of I >e< embeb h> 



A party of six members and guests visited the Wawayanda 



Cedar Swamp in New Jersey on December 10 on a cold clear 

 day. Tin- swamp was entirely frozen and two inches of ice had 

 formed on the pools. 



Lichens were in fine condition and grew luxuriantly in the 

 swamp area. Graphis recta, with black lines of fruit parallel to 

 the lenticels, was found in abundance on a fallen yellow birch 

 log. Graphis scripta, with the fruit more irregularly placed, was 

 discovered on the bark of an oak. Throughout the swamp, in 

 especial abundance on tree trunks, the silvery gray thallus of 

 Pa rm el ia physodes with upturned, frosty sorediate-tipped lobes, 

 was in sight. Other Parmelias were also common in the region. 

 P. caperata, a yellow green mat on tree trunks; P. conspersa, a 

 straw colored mat with a dark green center and chestnut brown 

 apothecia, on rocks; P. saxatilis with narrow gray thallus lobes 

 marked by net lines on the upper surface, on tree trunks; P. 

 rudecta, with broad gray lobes and with coralline (isidoid) sur- 

 face in the center, on trees; and P. subaurifera an olive green mat 

 closely pressed to the tree trunks and bursting here and there 

 with masses of yellow soredia; were all observed. In the swamp 

 the light gray, foliose Cetraria atlantica was found on the branch- 

 es of conifers, and the crustose Pertusaria velata, with lighter 

 margin and immersed apothecia and Buellia myriocarpa, with 

 tiny black apothecia and hardly any thallus, on the trunks of 

 other trees. Cladonias too were not lacking. The ubiquitous 

 red -topped Cladonia cristatella and gray-cupped C. chlorophaea 

 were of course everywhere. Cladonia coniocraea was found with 

 brown apothecia tipping its slender awl-shaped podetia. The 

 fruit is rather uncommon in this region. Cladonia bacillaris, a 

 slightly stouter species with more sorediate podetia, was also 

 found. Cladonia incrassata with sorediate podetia and red fruit 

 mostly on one side of the podetia, and C. delicata, a tiny brown- 

 fruited form which has finely cut fern-like primary squamules 

 bearing granular soredia, were also discovered. A few greenish-
