Phorbas fictitius

(Bowerbank, 1866)

Tony Gilbert This looks like Crater sponge Hemimycale columella, and not Phorbas fictitius (oscule rims and body same colouration). The specimen was quite small as mentioned, and I've noted that its at its northernmost distribution areas (I saw one in Mull 2 years back). https://www.facebook.com/groups/seasearch.identifications/permalink/463530950336888/?notif_t=like#!/photo.php?fbid=188368181297273&set=a.173485702785521.38902.100003722780643&type=1&theater
