NOTEWORTHY LICHENS FROM MAINE.— II 
G. K. Merrill 
The Lichens described in the following pages, with two exceptions, were 
collected in Knox County, Maine. 
Pterygium pannariellum Nyl. Sallsk. pro F. et FI. Not. iv, 1859, p. 236. 
Thallus brownish or blackish, adnate, small or somewhat spreading, narrow- 
laciniate and radiant toward the circumference, microphylline, sub-coralloid, or 
verruculose and sometimes cracked centrally, laciniae plane or slightly convex. 
Apothecia small, variously plane convex or concave, margins rather flexuous, but 
with no visible exciple, black. Spores, eight in each ascus, ellipsoid, hyaline, 
three-septate, 18-20X6^, paraphyses distinct, slender, septate, hymenial gel. 
with I + deep-blue. 
On moist mica-slate, Camden. 
Resembles a minute Physcia obscura. Tuckerman includes several species 
of Pterygium under his section Lecothecium sub Pannaria. The present is desti- 
tute of hypothallu^ and in no wise to be correlated with Pannaria. Not hitherto 
reported from America. 
Baeomyces RUFUS var. subsquamulosus Nyl. Flora 1877, p. 463. 
Distinguished from the species by its more squamulose thallus, and small, 
sessile, scattered or connate, simple or conglomerated brown apothecia. On 
sandy and turfy earth among mosses. South Thomaston. Previously unre- 
corded in America.
