If it is soft and mushy, it is rot and in that case I would just carefully cut out that small area.

Roots look fine to me!

Lighting?

I just restarted those as well so we will see. The ones I planted late last year never germinated.

#1 Looks like an etiolated version of some species of mammillaria

I agree with Steve.

I planted another batch of the Prickly Pear seeds and I think I got a couple germinating! So excited!

I would take some of these with the Mammillaria prolifera if you just want to send them all together.

Sent the PM! Look forward to the seeds! Thanks!

I will take some if they are still available.

Florida Cactus in Apopka, FL is worth the trip! Trust me their selection of cacti and succulents is amazing! I want to go back so bad. On a side note their prices are very reasonable as well. Staff is also extremely friendly and is willing to try and go out of their way to help you find something if...

Thanks! Very helpful information!

Not to get too off topic here Dave but can the normal growth that are removed be planted as a regular cutting and be grown independently as a 'normal' plant?

# 4 is Cereus jamacaru monstrose, not Cereus Forbesii monstrose (which is something entirely different)

The first picture in WayneByerly's post is 'Ming Thing' Cereus forbesii monstrose.

The second picture is definitely something entirely different, Cereus jamacaru monstrose.

I happen to have both of those.
