Tuckerman in Qbs. 1864, p. 285, {Syn. II , p. 135,) unites the 
two species as A. cyrtodes. The species is defined as follows: 
“ Thallus thin, glaucous-ash-colored, subcartilagineous, uneven, 
rimulose, somewhat limited by a black hypothallus. Apoth. about 
middling sized, adnate, rounded, convex, brownish-black, within of 
the same color. Spores oblong-ellipsoid, decolorate or rarely brown, 
10-12 locular, and now muriform-divided, often curved, 3-5 times 
longer than broad. 
“a. cyrtodes. Thallus greenish-glaucescent, the hypothallus 
less distinct, the spores oblong-ellipsoicl, the sporoblasts entire.

“ 1 ). disteudens, Nyl. Thallus at length cinerascent, the hypo¬ 
thallus black. Spores more oblong, now muriform-divided.— Exs. 
Wright Cub., n. 246.” 
309. A. subcyrtodes, Willey. Thallus thin, white. Apoth. 
rounded, convex. Spores 4-8, oblong-ovoid, muriform, the trans¬ 
verse cells about 8, the longitudinal in the centre about 3. .022-27 by 
.007-11 mm.— Suppl.,p. 54.—Florida in hb. Calkins. Only a sin¬ 
gle small specimen has been seen. 
310. A. spectabilis, FI. Thallus thin, white, indeterminate, 
continuous or rimose. Apoth. irregular, difform, angulate or ob¬ 
long, plane or convex, often bordered by the thallus. Spores ellip¬ 
soid, brown or decolorate, muriform, .030-36 by .010-15 mm -1 fig¬
