Diagnosis
ReferenceDiagnosis
A. Ernst et al. 2011Reticulate funnel-shaped colonies consisting of sinusoid, relatively wide and thick branches jointed by wide and short dissepiments, or fused together by anasto- moses. Autozooecia arranged in two rows on the branches, opening onto outer surface of the cone. High median keel widening apically. Vesicular skeleton (kenozooecia) often developed. Autozooecial chambers rectangular in mid- tangential section, short and relatively high, with mod- erately short vestibules. Axial wall straight to slightly sinusoid, projecting in the median keel. Hemisepta absent. Heterozooecia represented by brood chambers in orm of roughly rounded voids (?enlarged zooecia), situated preferably near dissepiments.
