cf. Micromussa pacifica
Button scolys were IDed as Micromussa pacifica by the hobby's taxonomy nerds such as Jake Adams and Joe Rowlett once that species got described, but this identification is dubious. First of all, no specimens from Western Australia, the locality where button "scolys" are collected from, were sampled in the study that described Micromussa pacifica. Second of all, there are notable differences in color between M. pacifica and button scolys: M. pacifica are usually a deep red or green, often with white radiating accents on the outer coenosarc, while button scolys usually range from red to yellow, often with "weak vescicles" denoting primary septa. The West-Australian population of button scolys have yet to be studied and likely represents an undescribed species within Lobophylliidae, separate from M. pacifica. Until molecular/genetic analysis is done on button scolys, we cannot definitively ID them.
