What species are these?

[DSDoyle]

Hello,



I have purchased the pictured brains from two different LFS.* One shop said the one they sold me is a Trachy and the other was sold to me as a Welso.* They look like the same species to me!



Any ideas?



Thanks,



Don

Trachy (geoffroyi). Wellso is now a trachy I believe but it’s the (radiata)

How can you tell? Heck looking at photos of both Trachy and Welso I cannot tell the difference

The trachy radiata which is formerly known as the wellso is dome shaped with all the raised structures making complete contact n the center and the mouths r surrounding it on the outside. The trachy geoffroyi"˜s mouths r down n the center and surrounded by the raised structures that don't touch.
