description

description
DESCRIPTION Erect, tubular fragile colony, arising from an encrusting uniserial basis. Zooids forming slender bifurcating cylindrical branches, ornamented by thin growth lines and scattered slightly prominent verrucae (pseudopores).
discussion
REMARKS The gonozooid, characteristic of the genus, consisting of a simple elongated chamber with a terminal tubular ooeciostome (J. - G. Harmelin, personal communication), was not observed. The encrusting basis is visible in some of the studied specimens (Fig. 6 B). The species created by Neviani (1895) from the Pliocene / Pleistocene of northern Italy, A. jullieni most probably corresponds to the encrusting basis of A. verrucosa. However, the homonymous A. jullieni described byOstrovsky (1998) from the present-day Antarctic is a different species. Peristome diameter and length are smaller in A. verrucosa and the prominent verrucae associated with the pseudopores are absent in A. jullieni.
