Mushrooms in Schefflera Soil After Repotting: Fungus Spores & Oversized Pot Risk

Yellow Mushrooms in Large-Potted Schefflera: Cause and Concern

Cathy's 9-ft schefflera in a 28-inch pot (repotted April 2006) lost 3 leaves and grew a pale yellow mushroom. Room has filtered south light.

Mushrooms = fungus spores in new soil—not harmful, not cause of brown leaves. Scrape out mushrooms + surrounding soil; repeat as needed.
Major concern: Pot is too large. 9-ft schefflera needs 14–17" pot. Oversized pot retains moisture → root rot risk.
Action: Let soil dry deeply; water sparingly when dry.
Light check: How filtered? Blinds/sheers? Distance from window?
