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.

Lichens! Rhizocarpaceae revised: Catolechia, Poeltinula, & Rhizocarpon refined, Epilichen to Catolechia, R. hochstetteri complex to Poeltinula, and Rehmia resurrected. Big changes affecting many areas in the world! Möller et al. 2025. Fungal Syst. and Evol. 16:215–231. doi: 10.3114/fuse.2025.16.12

A fun collaboration led by Alan Fryday, @ddiazescandon.bsky.social, Tracy Thai and several colleagues from the Grootbos Nature Reserve in South Africa, with a bonus revisit of the class Lichinomycetes plus a novel, very strange ITS insertion link.springer.com/article/10.1...

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.

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

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.

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