were : Rinodina oreina, Acarospora fuscata, Lccanora riihina, 

 L. cinerea, Rhizocarpon petraeum var. conjervoides, Parmelia con- 

 spcrsa, Amphiloma lanuginosuni, and Biatorella claviis. On the soil 

 at the grassy edges of bare places near the top were several Clado- 

 nias: C. cristatclla in ffs. ahhreviata, vestita and raniosa, C. chloro- 

 phaea i. simplex, C. baciUaris &s. clavata and pcritheta, C. plenrota, 

 C. papillaria f. molariformis, C. apodocarpa, C. cacspiticia, C. conio- 

 craea f. ceratodes and C. squamosa. Urccolaria scuposa var. para- 

 sitica was found on the Cladonia squamules in two places. A Httle 

 Peltigcra sorediata and some Baeomyces roseiis were found, but 

 the party was unsuccessful in searching for members of the Cladinae 

 or Unciales groups of the genus Cladonia. Perhaps the fires had 

 completely exterminated these. An old dry log yielded Parmcliopsis 

 aleurites and an undetermined crustose lichen. 



After lunching in a sheltered cove near the top of the mountain, 

 the party continued northward along the Appalachian trail. Pelti- 

 gcra sorediata was fruiting on the clay roadbank near the moss 

 Buxbaiunia aphylla which was fruiting and in prime condition. 

 Rock surfaces down which moisture was trickling yielded : Der- 

 inatocarpon aquaticum, Lecidea alhocaerulcsccns, Peltigcra prae- 

 tcxta, Cladonia pityrea and a species of Collema. The clay of the 

 road was covered by Dicranella heteromalla, frequently interspersed 

 with Pogonatum hrevicaide. Along the edges Cladonia mitrula fis. 

 imbricatula and pallida, C. verticillata f. evoluta, C. chlorophaea 

 ffs. simplex and carpophora, C. nemoxyna f. phyUocephala, C. fur- 

 cata, and the liverworts Ptilidiiim and Scapania were picked up. 

 At the base of oak trees Physcia endochrysea was common. Cla- 

 donia delicata and C. borbonica f. cylindrica were found on stumps. 

 A surprise w^as a thallus of Stereocaulon paschale growing on a 

 boulder at a low altitude, after it had been unsuccessfully sought 

 on the rocks at the top of the mountain. Witch hazel was in full 

 bloom ; and a few tardy asters and a single bellflower blossom were 



the only angiosperms still flowering.
