Next 'holiday #seaweed' is distinctive 'green sea fingers'! Three look-alike species are found in Britain. All belong to genus Codium; all are green #algae (so plants); one (C fragile) is invasive. Note peek-a-boo shrimp hiding in one photo: we'll return to them in our tour of Scottish rockpools!
Lepra corallina (white #lichen with peg-like isidia) infected by Sclerococcum sphaerale (black mould #fungus with grape-like sporodochia). Common fungal infection of this lichen species, but first hectad record. L corallina is itself common on stone in N and W of Britain. Above Loch Morar, Scotland.
Exceedingly few #lichens can grow as far down shore as Wahlenbergiella (Verrucaria) mucosa. It can survive lengthy saltwater immersion: note barnacles! Indeed, it doesn't occur above high tide: true #marine species. Common on British rocky coasts: this from Achaidh Mhoir beach near Morar, Scotland.
A few places left on my Beginner Lichen Microscopy online course! All basic technique, and live demonstrations. And bit more time to sign up: now starting 2 October by request of tutees already registered. Join them and me and look more closely at lichens, literally! aspenecology.com/beginner-lic...
I’m delighted to announce another opportunity to take an online beginner lichen microscopy course with Aspen Ecology! This beginner course will require...
More #seaweed from holiday. Gutweed (Ulva intestinalis) is green #alga (plant) often dominating upper-shore #rockpools. Looks a mess out of water, but underwater it's otherworldly: jungle of thin, intestinal tubes, bubbling with oxygen by-product of photosynthesis. Near Morar and on Eigg, Scotland.
