Ramalina leptocarpha Tuck. Suppl. Enum. N. A. Lich. 423.

Type: “There are several specimens” in the Tuckerman herbarium, 
Botanic Museum, Cambridge, Mass., “but no indication to show whether any 
particular one was the typ e,” fide Dr. W. G. Farlow. 
Type locality: “Monterey,” California. 
Original description: “ submembranaceous, thin, deeply lacunose or 
plane, canaliculate, smooth; apoth. lateral, sessile, with a thin elevated mar- 
gin.” /. c. 
Diagnosis: Thallus caespitose, compressed, canaliculate below, membran- 
aceous, rugose, apothecia lateral, spores curved. 
Description: Thallus caespitose at length pendulous (max. length 12 cm.), 
membranaceous, stramineous to pale virescent; cortex rugose, (puberulent?) ; 
laciniae compressed, often tortulous, canaliculate below, or throughout when 
immature, expanded above, at length foraminous (max. width 15 mm.), apices 
attenuate. Apothecia common, lateral and marginal, medium, concave at 
length convex, marginate (max. ciam. 8 mm.), disk buff. Spores ellipsoid, 
, 10-18 
curved, "375.7 M- 
Contingent phases: (a) More or less sorediate or soraliate on the margins 
and laterally ( = R. Menziesii f. sorediata Tuck., herb. Herre, Proc. Wash. 
Acad. Sci. 12 : 219. 1910). ( b ) Blackening. ( c ) Reduced and degenerate. 
Substrata: On trees, shrubs, and old wood [rarely “on the earth”]. 
Distribution: Common in the Transition Zone from Wash- 
ington to Southern California. 
Stations: California: Santa Monica Range; San Francisco 
Bay; Santa Cruz; Salinas; Mt. View Landing; Frenchman’s Tower; 
Los Gatos; Stanford University; Bolinas; Santa Rosa: Santa Bar- 
bara; San Diego; Berkeley; Searsville; Coast Range. Washington: 
San Juan Island. Lower California: Guadalupe Is. 
Observations: This species, recorded commonly from Cali- 
fornia, is far from well understood, especially to students of her- 
baria alone, and proved somewhat uncertain even to Tuckerman, 
who redescribed it under a new name ten years after his original 
Fig Dig notice. In its younger states it looks quite different from the fully 
tribution of developed condition, it becoming expanded and losing its canali- 
R. Menziesii. culate appearance with age. The canaliculate phases, however, 
need not cause it to be confused with the coriaceous R. canaliculata 
(Fr.) Herre, as they almost invariably show a few minute marginal apothecia 
which always contain curved spores. Its membraneous thallus also distinguishes
