Spell Trigger not working
I was playing Commander with Shelob, Child of Ungoliant. In my precombat main phase, I cast Monstrous Emergence, targeting the Mycotyrant, and Shelob to deal the damage. This should have triggered her deathtouch affect, sending the Mycotyrant to the graveyard and creating a food token copy. The creature, however, was not destroyed by the affect, as shown in the image. In response to my spell, my opponent cast Inscription of Abundance, but none of these provided a counter to the deathtouch trigger from Shelob's damage.

Read Monstrous Emergence carefully:
"Monstrous Emergence deals damage ..."
Since Shelob is not the source of the damage, it having deathtouch is irrelevant here.
