137 - A. leiicastnvn, Tuck. Thallus effuse, white, mealy. Ap- 
oth. reddish-brown, innate, oblong and elongated, plane, at length 
confluent in a radiate-stellate pseudo-stroma, white pruinose, the 
hvpothecium dark. Spores ovoid, 4 locular, the extreme cells larger, 
the middle ones now divided, .012-16 by .005-7 mm. Reaction 
vinous red.— Gen. p. 220.—Texas. 
138. A. chiodectoides, Nyl. Thallus glaucescent, thin, uneven, 
at the circumference cottony. Apoth. livid brown, difform, convex, 
white pruinose, within dark. Spores ovoid-oblong, 6-8 locular, and 
now somewhat muriform-divided, .023-35 by .012-15 mm. Reac¬ 
tion from blue vinous red.— Flora 1869, p. 72.—Bengal. 
139. A. interducta, Nyl. Similar to A. caribcea , but the apoth. 
blackening, paler when wet, crowded, somewhat dendritic-ramose, 
slender. Spores ovoid, 4 locular, .018-25 by .007-9 mm -> but ac¬ 
cording to Tuckerman 5-7 locular, all the narrower sporoblasts 
broken into smaller ones, and the spores becoming thus submuri- 
form-multilocular, the large terminal sporoblasts remaining entire. 
Reaction blue. Pr. N. Gr., p. 98.—Nicaragua. Hawaii, Tack.

140. A. herpetica, Mey. Thallus -. Apoth. brown and 
blackening, orbicular or obtusely angulose, thin, plane. Spores 2 
locular, the upper cell larger and entire, the lower muriform divided,

Revis. Mey., p. 318.—Manila. 
141. A. subvinosa, Leight. Thallus thin, white, limited by a 
black line. Apoth. brown, innate or depressed, in punctiform thal- 
line prominences, aggregated in simple divaricate-ramose or vari¬ 
ously formed linear series. Spores obovate, muriform. Reaction 
of the hymenium vinous red, of the spores bluish-gi een.— Ceylon , 
p. 180 and t. 36 f. 26.—Ceylon. 
142. A. atrorufa. Mull. Arg. Thallus greyish white, thin, rim- 
ulose. Apoth. blackish when dry, when wet reddish or reddish- 
brown, innate and emergent, elliptical or suborbicular, here and 
there confluent and somewhat branched or substellate, often sharply 
angulose, plane, within pale. Spores oblong ovoid, 6 locular, the 
cells once divided, .020-23 by .007-8 mm.— Beitr., n. 1099.—Aus¬ 
tralia. 
143. 4. -. Thallus white, continuous, determinate. Apoth. 
dark reddish brown, paler and bright red when wet, adnate, rounded, 
angular or difform, convex, rugulo.se. Spores muriform, ellipsoid, 
brown with age, about .038 by .015 mm. long. Reaction vinous red.

from which it is distinguished by the color.
