Sitka (Trelease, 1169) ; Kadiak (Trelease, 1170 in part) ; Unalaska 
(Trelease, 1154) ; St. Paul Island (Trelease, 930). Collected on St. 
Paul Island by William Palmer, and reported by Nylander, under the 
synonym Physcia lycimea (Ach.) Nyl., as occurring on St. Lawrence

on rails with Buellia 7 nyriocarpa chloropolia. 
iSS. Theloschistes lychneus pygmaeus (Fr.) Tuck. 
Parmelia parietina 1 . pygmaa Fries, L. E. 73. 
Theloschistes lychneus pygmaus Tuckerman, Syn. N. A. L. 1 : 51. 1882. 
Muir Glacier (Trelease, 1167); Sturgeon River Bay, Kadiak 
Island (Trelease, 117 1 ) > Unalaska (Setchell) ; St. Paul Island (Tre¬ 
lease, 8S6, 1173); St. Matthew Island (Trelease, 1172); St. Mich¬ 
ael (Setchell). This species has been collected on St. Paul Island by 
J. M. Macoun, who states that it is ‘ rare.’ Also collected on St. 
Paul Island by William Palmer, and in Alaska, no locality given, by 
Dr. Kellogg, and on the islands in Bering Strait by Wright. 
Nos. 1172 and 1173 are sparingly fruited. No. 1173 was found 
growing with fragments of Physcia on tufts of moss. 
1S9. Theloschistes polycarpus (Ehrh.) Tuck. 
Lichen polycarpus Ehrhart, Plant. Crypt. 136. 1785. 
Theloschistes polycarpus Tuckerman, Syn. N. A. L. 1 : 50. 1882.— Sowerby, 
Eng. Bot. t. i/gj. 
Muir Glacier (Trelease, 116S) on Salix ; Kukak Bay, Alaska 
Peninsula (Coville and Kearney, 1515^) ; St. Paul Island (Trelease, 
1174) . Mixed with the specimen from Kukak is a fragment of Phys¬ 
cia sp. All are fertile. A specimen collected by Professor Setchell 
at St. Michael may possibly be placed here. Rothrock, in his list 
based upon Dr. Bean’s collection, places this as a variety under T. 
farietinus , and writes: “Widely diffused over the Arctic regions 
and apparently very common, being obtained at a number of points.” 
In his correction of Rothrock’s list, Nylander refers the specimen to 
Physcia lychnea , a synonym for T. lychneus. 
One additional species of this genus has been collected in Alaska— 
T. parietinus (L.) Norm., collected by Dr. Bean at Port Clarence, 
and reported by Babington under the synonym Partnelia parietina 
Ach.., as occurring at Kotzebue Sound.
