and Florida in hb. Tuck., and from Bermuda in hb. Farlow, called 
by Tuckerman A. atrata Fee , seems to be the plant here described. 
Spores in Farlow’s plant 4-6 locular, .018-22 by .007-9 mm - 
7 1 - A. fuscescens, F6e. Thallus fuscescent, limited by a dark 
line. Apoth. when dry dark-brown and blackening, when wet dis¬ 
tinctly brown, minute, simple, branched and stellate. Spores 6 
locular, the upper cell larger, .015-17 by .005-6 mm.— Ess. p. 56

scribed. 
72. A. serialis. Mull. Arg. Thallus pale reddish, effuse. Ap¬ 
oth. brown, irregularly orbicular, stellate-angulose, confluent or 
nearly so in nodulose-linear, somewhat flexuous, entire or obsoletely 
ramulose series, suffused with the thallus and somewhat cinerascent, 
at length naked, within pale. Spores oblong-ovoid, 6 locular, the 
upper cell larger, .021-23 by .009-10 mm.— Graph Fee, p. 56 ( non

73. A. variabilis, Mull. Arg. Thallus thin, white. Apoth. 
blackish-brown, paler when wet, variable in outline, from suborbic- 
ular, oblong, angulose, stellate, or larger and linear and now bifur¬

the extreme cells larger. (Dimensions omitted.) — Beitr. n. 1096.

75. A. polygramitia, Nyl. Thallus thin, white, somewhat

Lindig n. 817, from hb. Tuck., are 4-5 locular, the upper cell larger, 
.018-23 by .005-6 mm., and those of Wright Cub. n. 136 are simi¬ 
lar, and meagre Florida specimens in hb. Calkins seem to agree 
sufficiently with this plant. But Wright, n. 120 b, referred here 
with a ? by Mull. Arg. in Sched., has ovoid 4 locular spores, the
