Type Information
Type locality: Azores; (Schmidt 1929: 103) Notes: UC437295 may be a type.
General Environment
This is a marine species.
Description
Thallus globose or subglobose, hollow, moderately firm, dark green, to 14 cm diam., adherent to substratum by a tuft of rhizoidal attachments. Thallus dissecting out into individual utricles or pairs of utricles, the second utricle being produced directly from the parent utricle; mature utricles of adult thallus subcylindrical to slightly clavate, 265-530 µm diam., (2.5-) 3-5.5 (-6.7) mm long; apices of utricles broadly rounded but acuminate and slightly asymmetrical; utricular wall 2-3 µm thick, to 85 µm thick at apex, where it forms a more or less pronounced obtuse mucro; apical wall finely lamellate. Hair scars relatively abundant on certain utricles, forming band 350-650 µm below apex. Medullary filaments 60-110 -130) µm diam. Gametangia narrowly ellipsoidal to cylindrical, usually tapered anteriorly, 65-130 µm diam., 370-550 µm long, borne usually one (sometimes two, rarely three) per utricle, on pedicel 15-25 µm long, 720-840 µm below apex of utricle.
Habitat
Intertidal pools to 20 m.
Similar Species
Codium bursa (see Chacana 2002); the thalli of the two species are indistinguishable externally, the distinction being solely anatomical. Whereas in C. bursa occasional utricles may have asymmetrical and somewhat thickened apices, typically the apices are only slightly thickened (625 µm thick), broadly rounded, and not regularly acuminate as in C. elisabethae.
