Many interests but focusing my posts here on biodiversity of western North American lichens; including research on phylogenetics and taxonomy of lichens -- foundational for understanding all aspects of the biology of lichens. bmccune.weebly.com

The cortex of P. oregonensis is always P+ orange. The medulla can be P- or P+ orange.

The Red Spot Puzzle in Cladonia norvegica www.cambridge.org/core/journal... Rare lichen followers in the Pacific NW of North America: one rare lichen species has split into two. Although only 1 N Am specimen was sequenced, it appears we might have both species. Needs a close look here.

It 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.

Another big form genus, Lecanora, bites the dust. Actually, it started a while ago. These changes will affect names for many species on all continents. Ivanovich-Hichins et al. in the latest Lichenologist. doi.org/10.1017/S002...

This 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.

New key to N Am for former Sarcogyne. Unlike previous treatments, no Euro taxa of Acarospora or Sarcogyne with carbonized epihymenium were found in N Am, except A. lapponica... and the lichenicolous Sarcogyne pusilla. Knudsen et al. MycoKeys 122: 123–148 (2025), DOI: 10.3897/mycokeys.122.162675

The inimitable Jason Hollinger demonstrating how he trims rocks while preparing specimens of saxicolous crusts. I have tried his method with a battery powered mini angle grinder with thin diamond blade, clamping it to a stool, and it worked great. www.youtube.com/watch?v=sCcY...

Yes, I see what you mean. That part is a little cartoonish and the textural contrast of the soralia isn't showing. Thanks.

Thanks 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.

from 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

Great 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?
