Mycale microsigmatosa

Notes: Thick encrustations to repent branches with scattered membranous oscules. Surface smooth or with spined elevations (possibly made up by worm tubes or hydroid stalks). Skin transparent and thick; the orange to red color looks like curd beneath the dermis. Material from the Bahamas did not have microsclere spicules, but the identification was made from the skeletal arrangement, texture and color. Florida material only have part of the microsclere spicule complement, and variable among specimens.
