Aplidium proliferum

Erling Svensen Any body that would try to give name to this one? 2,5 cm high, South West Norway yesterday.

David Kipling Aplidium no-punctum?

Erling Svensen Never heard about that one.... ;-)

Erling Svensen I do not know - and nobody seams to know. So - I do not know. But it is very, very common here in Norway

Wilfried Bay-Nouailhat It can't be A. Turbinatum because each colony generally has only one system, with more accentuated lobes and 7-9 rows of stigmata and on the picture there are at least 12 rows. I don't know how is Aplidium proliferum but Erling's picture may fit the description. What do you think of this ?

Wilfried Bay-Nouailhat Erling Do you have other pictures of this Aplidium?

Erling Svensen Yes, Wilfried, it could be the A. proliferium. I will look for another picture.

Wilfried Bay-Nouailhat Hi, a few words about Gonçalo Calado's message. I think that I saw the same Aplidium several times at different places: in 2007 in Trebeurden (English Channel), in 2009 in Ria d'Arosa (Galicia) cf. right picture, in 2010 in Camaret (Brittany) cf. top left picture and many tiny colonies in 2011 in Rade de Brest (bottom left). I still hasn't found the name of this species. It's very similar to Morchellium argus, they both have 8 lobes around the buccal opening. It differs in coloration, more orange with a white ring around the buccal siphon and 6 red spots on top of each zooids. It is sometimes identified as Aplidium proliferum in many websites.

Sue Daly Ah, I've seen this one here in the Channel Islands too. How can I post a photo?

Chris Whitehead Can anybody identify this for me. It was found stuck to the underside of a rock in a pool at Bigbury-on-sea, south Devon. It was about 5cm across, fairly flattened in shape and of a tough, rubbery cosistency. Tunicates?

Chris Whitehead I think it could be Aplidium proliferum or Aplidium nordmanni, although it seems some authorities believe they're the same species anyway.
