Any ideas on what this cactus is called?
I was hoping it is a Mammillaria longimamma but I am not quite sure as it does not have a large tap root and the "bumps" do not seem long enough - any ideas??

Are we all looking at the same photos? This is nothing like an E grusonii seedling. They don't look like this at any stage.
E. grusonii develops ribs much later, and it has a lot more than this. If you link up the tubercles on little seedlings you'll still end up with a rib count of a dozen or more, double that on older plants. E. grusonii has flattened and transversely ribbed spines, but not hooked spines. Some Ferocactus have flattened and ribbed spines but they are hooked. The ones with straight spines mostly have smoother and rounder spines and I'd say this is one of those. The areoles on Ferocactus are white and tomentose, usually contrasting with the dark bases of the spines. E. grusonii has woollier areoles the same colour as the spines. E. grusonii has clear pale yellow, occasionally white, spines that maintain their even colour with age, and more of them than the pictured plant.
This is the closest I can come to the pictured plant, and it is quite different. Spines are white, otherwise it is a standard E. grusonii. No ribs yet, but enough areoles for around a dozen ribs.
Here is an areole on a mature E. grusonii. Coloured wool matching the spines. The spines are arranged over the whole areoles with no obvious centrals and radials, although the inner spines are longer and more flattened. The apex of mature plants have a lot of loose wool.

Hmm, interesting discussion. I haven't seen a small E. grusonii up close before, I have a middle aged plant, it's not huge yet but it's not really a seedling either.
The areoles and spines are wrong for E. grusonii in Lazy D's picture. And like Ian said, its a fero.
It gets confusing tho and I understand the confusion.

Here's to you, all you insidious creatures of green..er I mean cacti.
Gosh...it really sucks buying young un-named cacti getting them identified is not an easy task.
Just the thought of having to wait until the plant flowers to find out exactly what it is, is frustrating
I buy these "seedlings" fairly cheap - about $7 which converts to about US$3.50 but I am going to have to wait YEARS before they actually flower!!

Thanks Ian, I have been toying with the idea of buying some mature cacti but I am not sure about the shipping costs and then ultimately how much I am gonna have to pay to clear them when or if they actually reach here.
I am going to buy some seeds though and see how that goes first.
My birthday is coming up soon so I am waiting to see if the bf has been paying attention to my hints If not I am going to start ordering like crazy!
