Mystery Cone-Shaped Objects in a Northern California Garden

While weeding a garden in Northern California, a gardener discovered several cone-shaped objects nestled in what appeared to be plant roots. Uncertain whether they were seed pods or something else, they sought identification.

Expert Answer: The objects are likely bird's nest fungi (family Nidulariaceae), which thrive on decaying organic matter such as wood mulch. These fungi are common in garden settings and are often mistaken for seed pods due to their shape. Viewed from above, their distinctive cup-like structure with "eggs" (peridioles) becomes apparent. They are harmless and actually beneficial, helping break down organic material. A quick search for "bird's nest fungi" will yield many comparable images.
