Just taken delivery of 3 new Cacti and would like to know what they're so I can read up about them please. Also noticed the brown spotting on the largest one, is this ok? Thanks for any feedback.

Brown spot marks

#1 is

Yellow Tower (Parodia lenninghausii)

Nice plants!

The other 2 are mammillaria carmenae(B) and (C) belongs to the genus Pilosocereus

Thank you Baja and Stefan. Very pleased with the yellow tower and Mammillaria they seem really healthy.
The genus Pilosocereus however when it arrived has the brown spots on it in the photo and feels very mushy. I'm guessing it's been overwatered from the supplier, I've left it to dry before planting. Is it too late and has the rot set in with the brown spots?

Ooh, that lil' Mammillaria is cute.
