Couldn’t it be a Phlebopus species – these are non-mycorrhizal which seems to fit your habitat (in grass) – unless there were mycorrhiza-forming trees around.

Thank you for all of the comments!
The specimen(s)were realy old and it might have confused cetain people.
You really have an acute sense of vision!

These mushrooms were collected under oak trees and therefore I would like to
suggest maybe Boletus aetivalis…?

The other species, as far as I can determine, do not occur in SA.

Would go for

Boletus pinophilus too

Wrong colour

Too much "sky"blue in the picture, I think the true colour is more like dark reddish brown..

I’ve looked for information about the South African “Boletus edulis”, and that was quite interesting. I found pictures of large harvests, and most of them had surprisingly pale caps, but that’s probably because they have been picked while they still were hidden in the duff under the pines. Another thing I noticed, was that the surface of the tubes was quickly darkening. That, and the fact that they were introduced to South Africa with pine plants, makes it most likely to be Boletus pinophilus. And that’s what I see in this link too:

I’m not sure what this observation shows though, not enough details in the picture. It might well be Boletus edulis sensu lato. That name is commonly used when they are for sale, and includes pinophilus, aereus, reticulatus and unnamed varieties among others (like the californian one for example).

if that purple color is true, it can’t possibly be edulis…

but Tylopilus is another sort of bolete.
