Strombocactus Disciformis?

[Ace]

What do you think of this fella? Strombocactus Disciformis?

Also, is this a Dioclethe (syn. mammarilla) longimama?

Please let me know guys - the top cactus has me really wondering - had a look thru an ID book last nite - all seems correct, apart from the stance of mine (mine is a lot taller than the disci's) and the spines are meant to fall off as the age (perhaps mine is just well looked after? )

hey man, I reckn you got the genus right but not so sure about species

Id say spination on both are to long for the species you reckn

[Ace]

Bugger! I will have to keep searching online for IDs - in the meantime, does anyone have any ideas as to what they both might be, or have any refereces to good ID websites?

Edit: Man, there is no pics online apart from disciformis I have found THIS site that has disci's that look more like mine. Any thoughts?

Or HERE. But the spines on the disciformis are much shorter - mine seems somewhat different...

not sure what that is, but its not a strombocactus

[ferret]

might have luck searching for Dolichothele longimamma

or mammillaria

[Jack]

Thelocactus maybe?

[Ace]

I found a few thelocactus's that looked somewhat similar, but I still cant find a correct ID for it...

A couple Mammilaria's that come very close:

- Mammillaria amajacensis

- Mammillaria rekoi subsp. leptacantha

- Mammillaria winterae

The rekoi I think is incredibly close - anyone agree?

I'd say the first is a Mamm, can't remember what species though. The second is a Mamm too, but not longimamma.
