Recognized by sight: In the last and second to last images the sporocarps in the center looks like they are pinched just before the head, a sign of H. calyculata. If there spores in the stems they would be Trichia decipiens, whos stems upper section is hollow and filled with spores.

Consistent with H. calyculata, not T. decipiens, according to Stevenson & Stempen Handbook 1994.
Spore dia. 7 mm (not 10-13 mm)
Elaters interlocking and blunt (not free and tapered)
Calyculus with petaloid margin.

Thomas Laxton, Thanks for this info and links.

Very helpful, I’ll check the stems more closely.
