genus, Dermatina, distinguished by the chemical reaction and 
elliptical or suhpyriform thekes, and in many respects resembling 
Mycoporum. 
320. A. abnormis, (Ach.) Nyl. Thallus thin, white, determi¬

regularly angulose and obsoletely stellate. Spores oblong, muri¬

.008-11 mm. Reaction from blue, violet; of the spores yellow.—

common in New Bedford on red maple. The spores are mostly 
colorless, but Nyl. has referred here also a plant with smaller, ob¬ 
long-ovoid, at length colored spores, .018-28 by .009-13 mm., now 
much resembling A. radiata, which occurs in New England and also 
in Florida in hb. Tuck. But the lichen also occurs on white pine, 
New Bedford, not differing, apparently, from that on red maple, 
with the spores only .022-28 by .009-13 mm.—A widely distributed 
plant, occurring in Chili, New Grenada, Europe, and in the United 
States from New England to Florida, in Illinois, and probably else¬ 
where. 
322. A. albovirescens, Nyl. Thallus white or greenish-white, 
somewhat leprous, effuse. Apoth. punctiform, convex, within pale. 
Spores ellipsoid, muriform, the transverse cells 6-10, the longitudi¬ 
nal about 4, .010-22 by .009-10 mm. Reaction fulvous red. — Tor- 
rey Bulletin 1889 ,p. 105, and Lich. Ins. Guineens. p. 51.— Florida
