Key to genera of Conescharellinidae

1. Colonies conical with circular cross section, or stellate 2

— Colonies not as above......................... 4

2. Autozooids and avicularia frequently in antapically direct- ed, alternating series. Autozooids not very prominent marginally; kenozooids forming a central core or as antapical layers.......................... Conescharellina

— Colonies stellate, without central core of kenozooids, autozooid orifices often arranged quincuncially, marginal zooids prominent; avicularia often absent.......... 3

3. Colonies with elongated peripheral peristomes; antapical avicularia and cancelli rare............. Trochosodon

— Colonies with prominent central root kenozooid Ptoboroa

4. Colonies compressed laterally in one plane......... 5

— Colonies compressed antapically in one plane, often branching...................... Crucescharellina

5. Colonies with a laterally compressed cone, becoming fan-shaped, zooids on each face separated by a narrow band of kenozooids.............................. Bipora

— Colonies leaf-like, with no intervening kenozooids between two interdigitating, frontally budded series of zooids..................................... 6

6. Lateral margins of colonies serrated, often with groups of prominent zooids or enlarged avicularia..... Zeuglopora

— Lateral margins not serrated, colonies sometimes trilobate.................................. Flabellopora
