Description
Escharella grotriani (Stoliczka, 1862) (Fig. 6 E-F)
Lepralia grotriani Stoliczka, 1862: 84, pl. 2, fig. 1. Escharella grotriani – Zágoršek 2001: 51, pl. 17, fig. 8; 2003: 157 (cum syn.).
MATERIAL EXAMINED. — Holotype, registered as 1862/0022/0051.
DIAGNOSIS. — Colony encrusting, the fragment comprising three short rows of autozooecia, these rhomboidal to oval with about 30 very small marginal areolar-septular pores. Frontal shield prominent, convex, smooth or slightly granular, with a small umbo. Aperture oval with a shallow lyrula and usually 5-7 oral-spine bases around periphery. Ooecium small, globular, recumbent on distal zooecium; ooecial aperture not preserved.
REMARKS
Escharella grotriani differs from Escharella tenera (Reuss, 1874) in having a small umbo on the frontal shield, 5-7 oral spines and broad, rhomboidal autozooecia. Zágoršek (2003) presented a detailed discussion of the generic attribution of this species.
