Comparison In thamnasterioid relationships of corallites and in corallite dimensions the genus resembles North American Campesteria prolixia Carruthers and Stanley, 2008,. However, Campesteria seems to have a different microstructure, as its distal septal borders show thick ornamentation resembling trabecular tips. [details]Diagnosis Thamnasterioid colony with circumoral budding. Central corallite large, with up to 90 septa (sometimes 2-3 central corallites) encircled by smaller corallites with up to 40 septa. Axial pits small and empty. Septal apparatus composed of septa from two to four size orders. Distally, septa S1 and S2 subequal in height and the highest of all other septa, have thick, rounded margins covered, like other septal surface, with minute granulations. Septal microstructural elements, in the form of long, fibre portions, emerge on septal faces as densely packed, sharply-ended granulations having 50-75 um in diameter. Dissepiments vesicular, abundant. [details]
Remark Two species were described up to now, the Alpine Early Norian M. hirsuta and American species from the Late Carnian-Early Norian from Nevada, M. silberlingi Roniewicz and Stanley, 2013. [details]
