Diagnosis. 
Zoarium branched and arborescent, of club-shaped, compressed 
branches, which dichotomize irregularly. The ends of the 
branches are flat. The apertures are crowded, and irregularly 
quiucuncial in arrangement. 
The sides of the branches are marked by longitudinal ridges, 
between whicli are the numerous oval pores.

Char. — Zoarium in-egularly funnel-shaped, Avitb a slightly expanded base, and 
the stem curved or straight. It is up to 5 mm. high and 7 mm. in diameter 
above. It expands above into a broad subcircular head, with a central 
depression. The apertures are irregularly scattered, small, and crowded. 
Larger on the margin ; linear faint vertical series on the stem. Marginal 
apertures *15 to *3 mm. in diameter. Some of the small ones are placed in the 
angles between the larger. Zooecia usually between *15 and -2 mm. in diameter. 
Distrib. — Cenomanian — Korycaner Schichten : Kank, Bohemia. 
Aff. — T he zoarium of this species gives it an apparent resemblance to Fungella 
dujnrdini, but with an irregularly obconic instead of club-shaped zoarium. 
It differs from Fungella, however, in the absence of mesopores ; for the 
instructive longitudinal section published by Pocta {op. cit. pi. iii. fig. 27) 
shows that the zooecia are monomorphic, so that the apparent mesopores are 
only sections across young zooecia. The species may be regarded as a 
Corymbopora with a simple, unbranched zoarium.
