Hammer - stem growth ID

[nthn135]

Hi all,

Looking for an ID on the two growths on the main stem of my hammer.

I *think* the lighter color growth on the left is a new head. No idea on the brownish one on the right.

Vermetids on right and left. Maybe baby head top mid right and another vermetid bottom rightish.
