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. https://bmccune.weebly.com

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)

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.

Common Lichens of Northern Alaska. This new short introduction to lichens produced by two scientists in the National Park Service helps open peoples' eyes to conspicuous species that they have never seen before! Very limited print run, but formatted pdfs are available: irma.nps.gov/DataStore/Re...

Pseudosolorina split from Solorina and Solorina crocoides split from S. crocea. The first part is easy because the species with orange below remain in Solorina. doi: 10.3390/jof11030169. Zheng et al. 2025. Journal of Fungi.

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