Is that 'Sea Lettuce'?

Ulva- sea lettuces & gutweeds

Sea lettuce is the name for a number of blade-like species of Ulva. U. lactuca is the best known but U. rigida can also be called sea lettuce. Distinguishing between them needs a microscope. The tubular species of Ulva, previously known as Enteromorpha, are commonly called 'gut weeds'. There are around 13 species of Ulva in B. Isles, 5 blade-like, the rest tubular.

The Seasearch guide to Seaweeds is a good book covering all the common seaweeds in B. isles. The definitive book is Green Seaweeds of Britain and Ireland, 2008. Edited by Juliet Brodie, Christine A Maggs and David M John. British Phycological Society. This has keys, colour photos, b&w photos, drawings.

buried

It's a shame, isn't it, that posts like this - good picture, informed and infomative text, get lost in history (buried 'neath a thick sediment of moths and mushrooms!)

more than..

This has more than enough wisdom to outweigh the Projects 'essential' criteria!
Please Jo. add the Tag ProjectA1. Please?

PS - Sorry it's MarineA1 (no spaces). ð

Rightful places

I think we should all add the Tag Marine Alga to these post as they are not plants in the accepted sense but Algae - I am going back though all mine to add the tag - this will help us in the 'distant' future, when Marine Algae gets into its rightful place here! Am I right?
I notice you have Green Seaweed, which is fine (me too in a few places). But maybe we could work to a single consistency - yes?
Tell me what you think Jo. I've dropped a few notes elsewhere.

Marine Alga tag

In the singular seems sensible.
Howver, can you clarify you preference -will we use Marine Alga or Marine Algae? I ask as I believe the search for one will not necessarily pick up the other.

And, are we no longer tagging Plant for these algae?

alga

Origin 7 Aug
We HAVE to use Plants (which should read Plants & Alga) as that is the (current) Group
I'm not fussed about the Group but sooner or later there'll be a crusade by someone.
My ploy is for Admin to be able to isolate ALL the Marine algae when the time comes. I think we might stick to alga as opposed to algae as it is more grammatically correct as a tag for a single species but hey Jo. I'm still technically only second year!

'marine alga' matters

A comment on your 'plants and algae': the Seaweed site says "Algae are very simple chlorophyll-containing organisms: some say that they are plants; other say that the are not, calling them protists or protoctists. According to the most recent phylogenetic studies, both are not quite correct. Some algae (most greens and the reds) are indeed related to the land plants, and some flagellated algae are related to the protists, but there is no justification for the including all algae in any generic term other than "algae"." http://www.seaweed.ie/Algae/algae.php

So I would not expect iSpot to adopt that grouping; marine alga is a good tag and when I get round to it I will re-tag mine appropiately.
