Discussion.—The type species of the genus Stellatophyllum Spasskiy in Bulvanker et al., 1968, S. lateratum Spasskiy in Bulvanker et al., 1968, is cerioid and with rather long major septa in the tabularium. However, Stellatophyllum belkovskiense is astreoid (as can be judged from the illustrations) and has septa withdrawn from the axis, thus meeting the criteria established for Smithicyathus in the present paper. From the morphological and numerical point of view it would make an almost perfect Smithicyathus smithi , if it were found in the Holy Cross Mountains, although it displays slightly fewer horseshoe dissepiments and less septal dilatation (Appendix 2: column “j”) than does the Holy Cross species. The Chinese material, as listed above, is with long septa in tabularium and most probably is not conspecific with the Siberian material, and it is still less probable that it belongs to Smithicyathus .
