have been deternr'ned by Dr. Eckfeldt and Mr. Merrill. (Pannaria 
lanuginosa (Ach.) Koerb.). 
Species Imperfectly Known or Excluded 
263. Arthopyrenia punctiformis (Pers.) Arn. E. Galway on trunk of Acer rubrum 
(Burt). This was marked doubtful in Dr. Burt's herbarium. {Py- 
renula punctiformis (Pers.) Hepp). 
264. Caliciopsis pinea Pk. Charlton on bark of Pinus Strohus (Peck) N. Y. 
State Mus. Rep. 33: 32. pi. 2 -f /. 11-15. 1880. According to Dr. 
Peck this was a fungus: but it is distributed among the lichens at 
the New York Botanical Garden. On bark of Pinus Strohus, west 
of Tripoli schoolhouse, old plants, Feb. 2, 1916; determined by Prof 
John Dearness. 
265. Cladonia decorticata (Flk.) Spreng. Gansevoort (Peck). This is un- 
doubtedly an error as this species is known from the White Mountains, 
N. H. It has been collected on Mt. Marcy in the Adirondacks, 
N. Y. State Mus. Bull. 25: 647. 1899. The Gan evoort plants 
may be referable to some torm of Cladonia pyxidata (L.) Hoffm. 
266. Cladonia sobolescem Nyl. Thin soil covering rocks at Dresden Station 
(Peck), N. Y. State Mus. Rep. 25: 647. 1898. 
267. Cladonia symphycarpa Fr. Including the var. epiphylla (Ach.) Nyl. Thin 
rorky soil, northern Washington county, determined by Dr. Eckfeldt; 
also Gansevoort (Peck). These plants should undoubtedly be referred 
to Cladonia suhcanosa Nyl. and C. cariosa cribosa (Wallr.) Wainio. 
268. Placynthium Petersii (Tuck.) Burnh., n. comb. "Rocks" and on stones, 
river bank below the falls, Glens Falls (H. Willey), N. Y. State 
Mus. Rep. 26: 49. 1874. Mr. Willey in N. Y. State Mus. Rep. 28: 
85. 1878 says, "the specimen reported under this name is 
not in good condition and therefore uncertain. " (Pannaria Petersii 
Tuck.). 
269. Blastema rupestris (Scop.) Zahlbr. Specimens from calcareous rocks at 
Shushan (Dobbin) and at Vaughns, should probably be referred to 
Caloplaca aurantiaca flavovirescens (Wulf.) Burnh. 
270. Caloplaca cinnabarina (Ach.) Zahlbr. Fort Edward (Howe), N. Y. State 
Cab. Rep. 22. 64. 1869. Specimens in Howe's herbarium collected 
in 1866 was labelled, "rare in swales near Troy." (Placodium cin- 
nabar ium (Ach.) Anzi). 
271. Caloplaca cirrochroa (Ach.) Th. Fr. Huletts Lg. (JelHffe). This species, 
which occurs on rocks, was not found in Jelliffe's herbarium: but 
given in a list of plants collected at Huletts Landing.
