157. Sticta oregana Tuck. 



Sticta oregana Tuckerman, Bull. Torr. Club 5 : 4, 20. 1873.

 Glacier Bay (Coville and Kearney, 779). Collected by Dr. Cooley at 

 Loringand at Sheep Creek, near Juneau. Tuckerman, in his Syn. N. 

 A. L., gives Oregon as the only station for this species. In my own 

 herbarium I have specimens from Vancouver Island and Washington. 



All the specimens are sterile with the exception of no. 339. 



158. Sticta pulmonaria (L.) Ach. 



Lichen puhnonarius Iat^-hjevs, F1. Suec. 1087. 1755.

Alaska (Evans, 6); Fraser Reach (Coville and Kearney, 311 in 

 part) ; Lowe Inlet, B. C. (Trelease, 1024) ; Juneau, 1800 ft. alt. 

 (Trelease, 1026, 1057) ; Juneau (Coville and Kearney, 608) ; Brough- 

 ton Strait (Trelease, 1022) ; Farragut Bay (Trelease, 1025 ; Coville 

 and Kearney, 474) ; Point Gustavus, Glacier Bay (Coville and Kearney, 

 780) ; Orca (Trelease, 1030, 1031, 1031a, 1038, 1045) ; Port Wells 

 (Trelease, 1029, 1029a) ; Aguadulce River, Yakutat Bay (Trelease, 

 1027); Attn Island (Townsend, 71). Dr. Cooley collected it at 

 Salmon Creek, near Juneau, Dr. Bean at Port Althorp and Sitka. 

 The specimens collected by Dr. Bean are placed by Nylander under 

 the following number as Lobaria liniia (Ach.). Under the synonym 

 Sticta pulmonacea Ach., Babington^ reports its occurrence at Kotze- 

 bue Sound. He writes : " The specimens are rather small, neatly 

 crisped, and pale ferrugineous below, approaching the form called S. 

 Unit a." 



This Alaska form differs from the type in various particulars. The 

 lobes of the thallus are broader and much more irregularly divided. 

 The lobes are usually round and crenate at the apex, while the type is 

 described as ' retuse-truncate.* The upper surface of the thallus is 

 lighter brown in color and not so deeply lacunose, while the under 

 surface shows fewer white spots. These specimens fruit much more 

 freely than the type. The apothecia are large, chestnut brown, granu- 

 late on the under side, and are scattered over the thallus and not 

 confined to the edges, as is usually the case in Sticta pulmonaria.
