Figure: Pl. X, f. 2. 
Diagnosis: Thallus caespitose (2 cm. alt.), subcompressed, nitidous, fora- 
minous to cribrate, apothecia terminal, spurred. 
Description: Thallus caespitose (2 cm. alt.), subrigid, stramineous to pale 
virescent; cortex nitidous, cribrate , laciniae subcompressed, dichotomous (max. 
width 3 mm.) apices attenuate. Apothecia common, terminal or subterminal, 
convex, generally marginate (max. diam. 4 mm.), disk wax color. Spores ellip-

sold, straight, ~ Q _ II p.. 
Contingent phases: Unobserved. 
Substratum: Trees. 
Distribution: Not uncommon in the Transition Zone from northern 
California northward to British Columbia and east to Idaho. 
Stations: California: Austrian Gulch; Oregon: Clarkes, Sanviers Is- 
land, Coast Mts. ; Idaho: Atmis Mt., Kootenay County; Washington: Cathle- 
ment, Seattle, Lake Washington; British Columbia: Comox. 
Observations: This not uncommon species seems only a robust condition 
of the former species, more cribrate, because perhaps presenting from its size a 
greater extent of thalline surface for foramina. R. inflata and geniculata, after a 
comparison of the types, appear identical, — the former name has only page 
priority. This is the most satisfactory species of the series, being distinctly fis- 
tulous, and appears to intergrade eastward into dilacerata, though distinctly more 
compressed. It has been misdetermined as R. Menziesii by distributois (Foster).
