Today the image archive of ITALIC has reached 10.000 species. Most images are released under a Creative Commons Licence, so you can re-use them for your projects. Thanks to everyone who collaborated!

Several species of Lecanora were segregated into the genera Straminella and Zeora in an important paper published a few days ago. Nomenclatural changes are now in ITALIC, incl. the keys.

Today the key to (potentially) Italian lichens has reached 3500 taxa. In the last years I was revising all keys alphabetically. Now I am at Verrucaria, a horror, but also the last mountain to climb.

URBAN FLOR@ - Glad to see that my old keys to plants were still useful for deriving updated keys to the urban floras of Italian cities: Empoli, Gorizia, Milano, Palermo, Pisa, Roma, Trieste…and others will follow!

The free app KEYtoNATURE is alive again. It permits to download on mobiles dichotomous keys by Project Dryades (Univ. of Trieste). Once downloaded, the keys can be used offline (e.g. in the field without internet).

Today they asked me for a photo of myself. I don't like selfies and had little to choose from. Perhaps the photo I like best is this one, from the Carnic Alps, while showing all plants growing in a square meter to my students (I miss them!)

Rome, October 21: Celebrating the legacy of Sandro Pignatti (1930-2025)

[Pier Luigi Nimis @plnimis]

Glad to see that data from ITALIC can be useful, less glad for the conclusions: "A dramatic reduction in habitat suitability of lichen biota is expected, with double amounts of loss under the high emissions than the mitigation scenario"...
