Need help with IDs for Ordovician brachiopods

[Misha]

Hello TFF friends, 

I recently recieved some Ordovician Brachiopods from Ohio and would love some help with getting IDs for them, 

First up are two Lingulid Brachiopods from the Waynesville Formation:

I have not been able to find much on the brachiopods from this formation, the brachiopods also look slightly different so I am not sure if that indicates some kind of different species or these are just differences between individuals. Both are about 1.5 cm in length

Next up are two rhynchonellids, these two are preserved together and are about 2 cm in width, perhaps Lepidocyclus sp.?

Then finally, there are some brachiopods that I believe are Platystrophia sp., also liberty formation:

 

Thank you for any help!

According to the literature the lingulids are Pseudolingula sp. 

 

This publication has an excellent section of Ohio brachiopods:

 

Feldmann, R.M. & Hackathorn, M. (eds.) 2005

Fossils of Ohio: Geological Survey Bulletin, 70:1-577

I agree with Pseudolingula sp. 

Then Lepidocyclus perlamellosum. 

Yes to Vinlandostrophia. Are these still from the Waynesville Fm?

Thank you!

The Lepidocyclus and Vinlandstrophia are both from the Liberty Formation
