Mystery Bulbs in Connecticut Mulch: Animal-Carried or Fungi?

Egg-Shaped Bulbs Appear in Flower Bed

A Connecticut gardener found egg-shaped bulbs on mulch with whitish membranes, fine black roots (like onion roots), no scent, brownish-to-peach color, and no holes in the property suggesting garden origin.

Expert Hypotheses

• Bulbs carried by animals (squirrels, chipmunks) from elsewhere.
• Possibly fungal structures (sclerotia) feeding on organic mulch.

Next Steps

Cut one open to confirm it's a true bulb (concentric scales) vs. fungal mass. A photo would enable definitive identification. The expert requested images sent to their email.
