a colony of the Blistered Rock Tripe, Umbilicaria pustulata on 

 several closely adjoining ledges, which bore brown apothecia, 

 instead of the usual black ones. Every apothecium on the thalli 

 in this area, several rods wide, was brown, while on other col- 

 onies, on the mountain top, the usual black fruit were found. 

 The thalli with brown apothecia did not appear to be diseased 

 or abnormal, and the color did not seem attributable to any 

 outside interference, such as eating by slugs or insects. In some 

 cases the brown color was almost reddish brown. I find no men- 

 tion of such a color in available lichen guides. 



Interesting crustose lichens found on this trip were Rinodina 

 oreina, which I have regarded as a plant of boreal islands in this 

 vicinity, usually finding it around 1,000 feet or above, although 

 there is some on glacial boulders on Montauk Point; and Le- 

 canora tartar ea, the dye and litmus producing lichen, occasional 

 in high places in the Highlands. Colonies of a pretty sorediose 

 Physcia, which Mrs. G. P. Anderson thinks is P. Clementina, 

 not before reported in North America, were also found. 



Cladoniae were ample in quantity and fairly varied in species, 

 including C. cristatella, ff. vestita and Beauvoisii; C. squamosa, 

 form undetermined; C. Floerkeana, C. coniocraea, ff. ceratodes 

 and truncata; C. borbonica, f. cylindrica, a somewhat unusual 

 species, resembling C. coniocraea at first sight and apt to be 

 mistaken for it but distinguished by the granulate and isidiate 

 soredia on the bases of the podetia, and by tiny brown apothecia; 

 C. uncialis, near /. dicraea; C. rangijerina, C. furcata, var. 

 racemosa, f. corymbosa;a.nd var. pinnata, f. foliolosa ; C. bacillaris, 

 C. papillaria, f. papulosa, C. caespiticia, and C. chlorophaea, ff. 

 simplex and carpophora. 



While working on the Appalachian Trail, on Kittatiny Moun- 

 tain, Warren County, N. J., a week later, and looking for more 

 brown-fruited Umbilicaria pustulata, I found the plant growing 

 on wood, the first time I ever saw it elsewhere than on rocks. 

 Several normal looking and fruiting thalli were growing .on a 

 dead stick, two feet long, which lay on boulders thickly covered 

 with this lichen, on the west shore of Sunfish Pond. These 

 boulders are densely coated with a variety of lichens, including 

 Rinodina oreina, Lecanora tar tar ea, Stereocaulon paschal e, Par- 

 melia conspersa and saxatalis, and Lecanora cinerea. 



Dr. A. W. Evans, of Yale University says he has never seen 

 Umbilicaria growing on wood, but notes that R. Heber Howe
