Characters. 
Entalophoridce ? with a cylindrical stem, terminating above in 
a lamellar expansion which has no apertures. 
Affixities. 
The relations of this genus are doubtful. It may represent 
a variation from an Entalophorid, in which the stem expands above 
into a vertical lamina, just as in Entalophora ammalissima it 
expands into a horizontal disc. The genus is not represented in 
the Museum collection.
