Bruce McCune @brucemccune.bsky.social · 07/06/2026It would be very unexpected to have the hyperoceanic species Pannaria oregonensis in interior BC. It would be good to confirm that it has cyanobacteria as the photosynthetic partner and is P+ orange. 100

Bruce McCune @brucemccune.bsky.social · 16/10/2025This has been discussed off and on for many years by NW Lichenologists, but so far no action on it -- there has been more demand on the west side of the Cascades. 100
Bruce McCune @brucemccune.bsky.social · 26/09/2025New key to N Am for former Sarcogyne.

Bruce McCune @brucemccune.bsky.social · 25/09/2025The inimitable Jason Hollinger demonstrating how he trims rocks while preparing specimens of saxicolous crusts.

Bruce McCune @brucemccune.bsky.social · 15/02/2025Thanks for the explanation. I take this as an Aesthetic Challenge. I will think about this as a former b/w photographer and darkroom enthusiast, which I did as much for financial and technological reasons as anything. 130
Bruce McCune @brucemccune.bsky.social · 14/02/2025Yoshihito, I am curious about your choice to go consistently with grayscale rather than color. What are your thoughts on that? Thanks! 111
Bruce McCune @brucemccune.bsky.social · 31/01/2025Wow, fixed already in Index Fungorum. Lecanora phryganitis lives. 120
Bruce McCune @brucemccune.bsky.social · 30/01/2025from Frank Bungartz (CLH): “This to me looks like a glitch in Index Fungorum that we probably just applied routinely in the Consortium. Especially if there is molecular evidence that it is closer to Lecanora we should change it.” See Lendemer 2013 Mycol. 105:994. Nothing to do with Teloschistaceae 110
Bruce McCune @brucemccune.bsky.social · 29/01/2025Great photo. Suprised to see this assigned to Polycauliona in the Teloschistaceae. Species Fungorum and CLH and both show the current name as Polycauliona. But blasting the existing mtSSU in GB comes out to other usnic-containing Lecanora, such as L. symmicta. Does anyone know why Polycauliona? 120
