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.

The lichen genus Protoblastenia mushrooms in Finland: "... based on morphology and molecular data (nuITS rDNA sequences). 20 species were recognised, with 16 species being newly described here..." Sure to be found in N Am and elsewhere... mycokeys.pensoft.net/article/162802 (Pykälä & Myllys 2025)

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.

Title and authors for Knudsen et al. 2025

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.

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

Looks pretty good. How would you refine it?

So Jesse, can you say what it was that got your attention? Can this be bottled and distributed?

Looks like a great opportunity for a PhD lichenologist at the Santa Barbara Botanical Garden in California, USA:

I've never seen pyracea with a well developed neatly lobate thallus like this. Not sure what it is.

A big revision for the Lecanora saligna group -- six new species in Lecanoropsis. This is a common group of crustose lichens in western North America and elsewhere in the Northern Hemisphere.

Pancakes? Looks like pumpkin pies (maybe not eaten in Scotland?); this is what we call Ochrolechia in western North America.

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.

Yoshihito, I am curious about your choice to go consistently with grayscale rather than color. What are your thoughts on that? Thanks!

Wow, fixed already in Index Fungorum. Lecanora phryganitis lives.

1 year ago 2 0 1 0

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?

eDNA and traditional biocrust sampling each have blind spots for biodiversity but tell a similar ecological story of disturbance in Artemisia steppe.
