Of course, I didn’t write down the pattern for the larger mushroom. Just sc in the round, then sc random “spots” on the cap.

The smaller mushrooms:

STEM
6 sc in magic circle, then sc around until desired height.

GILLS
Ch 2, dc in same, 2 dc in each sc around
Ch 2, sc in same, 2 dc in each dc around

CAP
This is tricky to explain without images, but I sc two rows around the dc’s, but on the wrong side of the dc and in the middle of the dc stitch. This left a “lip” going around the edge.

Then SC2TOG, 1 sc in next 2 sc around once
Then SC2TOG, 1 sc in next around to last six sc
Cut 6-8” strand and weave close. Use the end to sew the mushroom so the gills are more concave to the cap.
