Fam. 5. Pannariei.* 
Paynarta hypnorum (Vahl.) Delis. Rocky Moun- 
tains, alp., Mr. Hall. 
~ P. microphylla (Sw.) Massal. Coast; Mr. Bolander. 
N. Mexico; Mr. Fendler. 
P. lepidiota, Th. Fr. Coast; Mr. Bolander. 
Pannaria cyanolepra (sp. nova) thallo e granulis conglo- 
meratis cyanets hypothalo obsolescente; apotheciis 
minulis biatorinis rufo-nigricantibus, disco convexo 
marginem excludente. Spore octone, cllipsoidee, obtuse, 
simplices dein nebulosa, diam. 2-2} plo longiores, in- 
_ eclores. On the earth; ‘clayey soil near the North 
American river, Auburn;’ Mr. Bolander. Compara- 
ble with P. nebulosa (Hoffm.) Nyl. (Lich. Par. n. 
114) which appears quite the same with Zecidea coro- 
nata, Borr! (Hook. Br. Fl.) but the minute, steel- 
blue granules of the present scarcely coalesce into 
scales; and the apothecia differ. The simplification 
of internal thalline structure corresponds here with 
the reduction of the thallus, as in other species. 
Fam. 6. Zecanorei* 
Dirin Californica (sp. nova) thallo eubtartareo rugoso- 
verruculoso cinerascente ; apotheciis mediocribus confer- 
tis sessilibus, disco convexo margineque prominulo 
fleruoso-subcrenato cinerec-pruinosis. Spore in thecis 
elengato-clavatis suboctona, dactyloidea, tetrablasta, 
diam. 3—5 plo longiores, incolores. Spermatia acicu- 
laria, arcwata, sterigmatibus simplicibus. Trunks of 
Oak (Quercus agrifolia) in the Oakland Slough ; Mr. 
Bolander. In general: aspect not a little like condi- 
tions of Lecanora glaucoma, and comparable also 
with L. ( Lecania) fecunda, described below : but not
