p. 9. Acarospora succedens as previously applied by Knudsen is now A. nashii. Knudsen (2011) renamed his neotype of A. succedens to A. nashii. (Knudsen, K. 2011. Acarospora nashii, a lichenicolous lichen from western North America. Bibliotheca Lichenologica 106:169–172.)
p. 31. line 1. Arthonia phaeobaea also known from Alaska.
p 60. 2/3rds of the way down, "Thallus esorediate" should be lead 8b, not 9b.
p. 59. Bacidia bagliettoana, change 10-15 septate to 3(7) septate (illustration is correct).
p. 86. End of first paragraph, change "3-5-septate" to "3-9-septate". First line of lead 2a (Bilimbia sabuletorum), change "4-5-septate" to "4-9-septate".
p. 108, lead 2a. Hafellia fosteri should be Buellia fosteri.
p. 110, lead 13b. "Amandinea punctata" is meant to be listed as a synonym immediately below "Buellia punctata"
p. 150, lead 23a. Caloplaca kamczatica should reference p. 147.
p 171, lead 1a. "with distinct dark brown capa" should be "caps"
p. 173, lead 4a. Change Trentepohlia to chlorococcoid. (and therefore this character is not useful for couplet 4).
p. 230, last line references a water-soluble wax for sectioning in Vol. 1. This was inadvertently omitted. Here is the method, as written by Martin Hutten and Bruce McCune:
Embedding in PEG 3350
Materials: You will need a cigarette lighter and powdered water-soluble PEG 3350 sold as an osmotic laxative (Walgreens Smooth Lax® or Rite Aid's MiraLax® or look for alternatives containing polyethylene glycol 3350 or PEG 3350). PEG 3350 is a low-melting point solid polymer. When solidified it has a waxy consistency, but still dissolves in water.
Procedure:
1. Put specimen to be sectioned onto glass slide. The specimen should be dry or at most moist, with no excess water. Add a tiny amount of the PEG 3350, just enough to surround the specimen and no more. To transfer the PEG, use a small flat surface or an old glass dropper. (If you use the latter you can melt the granules while still in the dropper).
2. Gently heat the bottom of slide with a lighter, melting the wax granules. Stop heating just BEFORE all of the wax is melted.
3. Ensure that the specimen is completely immersed in the liquid (you may need to press it into the liquid), then let the wax resolidify. This will happen quickly if you set the slide down on a table. Some cracking around the edges may occur as it cools.
4. Trim excess wax.
5. The specimen is now firmly glued to slide and fully supported by the wax.
6. Section as desired. Support the side of the razor blade with a second slide or a finger.
7. Remove any unwanted specimen chunks and more of the excess wax as needed.
8. Add water or transfer slices to a water drop on a clean slide, add a cover slip, and view. The wax will not resolidify as long as you have water under the coverslip.
p. 325. Lecanora, Group 9. Delete lead 27b (superfluous).
p. 328 lead 8b should read "Spores usually >= 4 um broad", not "Spores usually 4 um broad"
p. 347 lead11a contrasting is spelled wrong.
p. 376 lead 2a C and KC reactions not indicated. Should be C-, K±Y, KC -.
p. 380 The ending of Leciophysma saximontana has been corrected to Leciophysma saximontanum.
p. 459 lead 9b. Change "porer" to "pore".
p. 461 lead 4b. Change "and" to "or".
p. 468 lead 10b. Change "2.5(3.5) um" to "2.5(3.5) mm".
p. 656 Photos 1:40,63 should be Photos 1:63.
p. 695 lead 7a. Change "Perithecial" to "Perithecia"
Index entries for Tephromela atra. Remove entry for p. 40.
