More Raasay News

December 4, 2019

A woodlouse found on the recent SNG outing turns out to be Philoscia affinis, a cryptic species only recorded in the UK in 2017 but likely to have been here for many a year as an undiscovered native. For now, this is the most northerly record on the planet.

Whilst checking the only known duckweed site on Raasay a couple of weeks ago, I noticed a plant in that small garden pond that I thought was Ranunculus subgenus Batrachium i.e. a Water-crowfoot. I sent a couple of pictures to Chris Preston, aquatic plants expert, who agreed. Sadly neither he nor I can get it to the species level without flowers and late November is not the time to find those. The only accepted records for linear-leaved water-crowfoots in the vice-county are of Ranunculus trichophyllus (Thread-leaved Water-crowfoot) from Storr Lochs on Skye. The Raasay one may have been introduced with purchased pond plants.



Today I spotted this little fungus on a twig in the garden:

I am hoping that someone will advise as to what it is…..   Later: Looks like a Hymenoscyphus though the species would need more work. Thanks, Seth.
