Very doffuclt to make out. I observed this taxon in seveal samples from Maryland now and it seems to vary from site to site. There are ones with wavy domes and one to several fultoportulae , but also flat domed ones and with one, but with same striation

Not sure if this is the taxon. It seems to be the same as that observed in other samples from Maryland, but this ones have a more clavate shape. Probably a Punctastriata
