Hit the beach today. That was it. No work, no hills, no woods, no nuffin' - just the beach. I was there for hours n' hours and oh boy did I ever have a fun time!
I concentrated on
seaweeds (naughty word) marine alga
and surprised myself by finding SEVEN new ones for my list. I walked
away from a couple of red alga that looked too nondescript to even
bother with (plus all the pink encrusting ones, Lithophyllums I believe), but basically grilled the rest including a few green
ones that required the microscope to clinch an ID. Ok, so I'll just
whack up pics with captions, lots of pics on this post!
I concentrated on
|Prasiola stiptata habbo shot - higher than the other species, often found where birds sit and crap.|
|Prasiola stipata - noticeable stipe which runs into blade, often several arise from a communal holdfast|
|Blidingia minima in situ where a freshwater burn runs across the rocks|
|Blidingia minima - cells not running in parallel rows (trust me...) hence not B.marginata|
|Cladophera rupestris - do-able on colour alone, but angle of branching and diagonal joins important too.|
|Choreocolax polysiphonia - it's the pale 'galls' on the Polysiphonia lanosa|
This was my find of the day - a truly tiny epiphytic colourless red alga that lives epiphytically on an epiphytic red alga, amazing! Took a lot of hard squinting to finally find some, then found several clumps on this one alga. Really pleased with this, a targeted search successfully completed. Talking of targeted searches, here are a couple more than worked out rather nicely
|Elachista fusicola - growing here on Bladder Wrack|
|Elachista fusicola - microscope pic (and hence duff...)|
|Membranoptera alata - epiphytic on Cuvie stipes|
Blimey, I never knew we had so many epiphytic marine algae, it's like a whole world full of bromeliads out there!!!
|Membranoptera alata microscope pic. Note the tetrasporangial sori in the blade at the bottom of the image|
|Hildenbrandia rubra - the red scuzz on the pebble. Massively prevalent across Uig Beach!|
They were the lifers, add to that a host of other species that I've already seen and I was having a whale of a time. Didn't even fall over despite schlomping through acres of wrack! So that's seven new alga, but I also managed a new lichen. Massively common in this habitat, I have to thank Ali for the heads-up (saw it on his blog...) Despite it being very common I managed the worst pics ever....
|Verrucosia mucosa - note the pale outline to the thallus. Proper shite shot, huh?|
|I don't care what the experts say, I reckon this is Doris pseudoargus!|
|Atlantic Eel Anguilla anguilla - note the Hildenbrandia rubra (red scuzz) on the pebble. Common as muck!|
|Idotea granulatus - commonest of the bunch but new for me (it's my 4th of the genus...)|
|Probably Breadcrumb Sponge Halichondria panicea, but possibly not|
|I dunno, question is - do you?|
