WILLIAMS: NOTES ON SOME WESTERN LICHENS 4) 
(00); with spores ns a, 1 should think Ochrolechia pallescens (L.) 7 
siti The spores of L. pallida (Schreb.) Schaer. are given as 
=r ary otherwise O. pallescens is very similar to L. pallida. 
36. Called Lecanora subfusca var. argentea Ach. This is cer- 
tainly the same as No. 34, or L. fruticulosa, previously credited 
in North America only to California, I believe. 
39. Called Lecanora epibrya Nyl. Dawson, July, 1898 (30). 
My specimens apparently not distinct in any way from the pre- 
ceding. 
40. In my set none of the specimens under this number (88) 
are distinct from No. 34. Lecanora castanea (Hepp) Th. Fr., as 
given in Howe’s list, does not seem to be represented. 
53. All poor specimens under this number (97), apparently 
charred by fire. They were doubtfully referred to Ephebe pubes- 
cens (L.) Fr. Collected at Dawson, July, 1898 (97). I think the 
species is rather Lecidea globifera Ach., from which I believe Biatora 
Russelliit Tuck. is not distinct. 
56. This is typical Solorina saccata (L.) Ach., rather than the 
var. spongiosa, which it is called. Collected at Dawson, August, 
1898 (35). The other specimen under the name S. saccata, from 
Lake Lindeman, May, 1898 (22), seems to be rather ocmtig: 
hypnorum (Wahl.) Koerb. The spores are not more than - Be 
and eight in the ascus. Solorina saccata has spores mostly four 
6-55: 
18-28 © 
Three other species referred to in the list proved to be inde- 
terminable in the duplicates sent out. I believe them to be as 
follows: ; 
CLADONIA GRACILIS CHORDALIS Floerke. 
Lake Lindeman, May, 1898 (6). 
BUELLIA COLLUDENS (Nyl.) Tuck. 
Dawson, December, 1898 (82), with no spores; Dawson June, 
in the ascus and™ 
16 ; : 
1899 (82a), with spores two-celled, about “— p, pale and eight in 
the ascus.
