@leigh_winsor Oh my! This one was over 80 mm long extended (see extra photos next to 80 mm ruler, though not fully extended in the photo). Darker, greyish head had a paler tip, but otherwise a uniform light pink color. Found on the underside of a small conifer log in an urban public garden. When placed in a bag and flipped over, you could see a small white oval (maybe a meal?) in the middle - look for the photo with the red arrow pointing towards it.

Wild guess on the ID since this genus has not been recorded before in California on iNat.

I also have video if anyone is interested.

Collected it in 95% ethanol (thank you @seaslugin) in case anyone is interested in sequencing or whatever, please message me.
