Red growth around severed flower stem on VFT

[Spintix357]

I trimmed a stem off of these recently replanted vfts and around the base of the severed stem weird pinkish growth has occurred. Can anyone tell me what this is? the severed stem has also become really fat. It is that big brown blob where the pinkish growth is surrounding

Methinks you have callus forming. Your plant is going into divisive overdrive and you may soon see dozens of tiny traps from several small growth points.
