I am studying palynomorphs originating from Central Grecce, Holocene epoch. I have found some brown cysts that I am not familiar with. I think that they could be Quinquecuspis concreta. Thank you in advance for your help!

DearElino Christopoulou,
The dinoflagellates are Lejeunecysta Artzner & Dörhöfer 1978.
In Hungarian: Eocene-Sarmatian.
Williams & al. 1993: Middle Eocene-Recent.
Best regards, Mária.
I agree with Mária Sütőné Szentai . It is Lejeunecysta. A peridinioid dinoflagellate cyst type.
These specimens could go into Lejeunecysta; not sure which species. I would recommend having a look at Reid 1977 where the differences between Quinquecuspis and Lejeunecysta are discussed. Let me know if you want me to send you the paper.
Dear Kenneth Mertens,
I kindly ask you to send me the article about Quinquecuspis-Lejeunecysta, to my email address ([email protected]).
Best regards,
Mária
These specimens can safely be placed under Lejeunecysta sp. For identification of species specimens will have to be examined under microscope.
Lejeunecysta is the fossil genus. May be the Holocene species of it.

Dear Elino Christopoulou,
It seems like a Leipokatium invisitatum, or its relative.
All the best,
Patricia Piacsek
