Genus Adeonella BUSK, 1884 View in CoL
Colony erect, flat and bilaminar. Autozooecial frontal wall well-developed, umbonuloid, smooth, with large marginal pores. The aperture has a crossbar structure, forming proximally a small spiramen and possessing a pair of small, oral avicularia. A median ascopore is not developed. Adventitious avicularia may be present. The brooding autozooecia (gonozooecia) are a little larger than ordinary autozooecia, but rare.

T y p e: Lectotype is deposited in the Natural History Museum Vienna under the number 1847.38.62. ( Vávra, 1977).
M a t e r i a l: Very abundant species, 5 specimens from the Vienna basin and 64 specimens from the Carpathian Foredeep were studied in detail. Most specimens were found at Vranovice, Kralice nad Oslavou and Holubice. Additionally 2 specimens from the Reuss collection stored in the Natural History Museum Vienna under the numbers 1859.50.973 and 1859.50.970 from a section at Sedlec were studied .
D i a g n o s i s: Erect, bilaminar colonies. Autozooecia rhomboidal in the central part, longitudinal in the marginal part of the colony. Lateral tubercles sometimes preserved on the margin of the autozooecia. Pair of small oral avicularia are situated on each side of the proximal margin of the aperture, one large median circular avicularium developed proximally from the paired avicularia. Internal brooding, no ovicell developed.
143 R e m a r k s: Studied specimens are identical with the type material. Autozooecia situated on the margin of the colony are usually much longer than those in the central part. Secondary calcification may change the general appearance of the colony considerably .
