134. Pannaria lepidiota coralliphora Tuck. 



Pannaria lepidiota coralliphora Tuckerman, Syn. N. A. L. i : 122. 1882. 



Hot Springs (Trelease, 962). New to Alaska. 



A small specimen on rock. This variety was described from ma- 

 terial collected at Vancouver Island by Professor John Macoun. I 

 have carefully compared this with the type specimen in the Tuckerman 

 Herbarium. The apothecia are not quite so convex as in the type 

 where the margin is excluded. The thallus of the type specimen is 

 nearly black, while this is a dark gray. No other localities are recorded 

 for the variety. 



135. Pannaria brunnea (Sw.) Mass. 



Lichen brunneus Swartz in Act. Upsal. 4 : 247. 1784.

 874) ; Hidden Glacier Inlet, Yakutat Bay (Trelease, 861) ; Unalaska 

 (Setchell); Hall Island (Trelease, 878a). Collected by Wright on 

 the island in Cross Sound and on Chernofski Island, and by Macoun 

 on earth and rock on St. George Island. 



A common alpine and arctic lichen. 



136. Pannaria hypnorum (Vahl) Koerb.

Hidden Glacier, Russell Fiord (Coville and Kearney, 965) ; Dis- 

 enchantment Bay (Trelease, 860, 879, 879a, 970) ; Egg Island, Dis- 

 enchantment Bay (Coville and Kearney, 1018) ; Muir Glacier (Tre- 

 lease, 876, 877, 877a) ; Hidden Glacier Inlet, Yakutat Bay (Trelease, 

 859) ; Orca (Trelease, 873) ; Port Wells (Trelease, 872) ; Unalaska 

 (Setchell) ; Hall Island (Trelease, 878a) ; Plover Bay, Siberia (Tre- 

 lease, 875); St. Michael (Setchell). This is a very common and 

 widely distributed alpine and arctic lichen, although the only other 

 Alaskan record is Unalaska, where it was collected by Dr. Bean. 



The specimens are usually well fruited, the apothecia varying 

 greatly in size and in the Indentation of the margin, which is some- 

 times nearly entire.
