Fluted Bird's Nest Fungus
Cyathus striatusFluted bird's nest fungus forms tiny brown cups lined with vertical grooves and filled with dark egg-like spore packets. Raindrops striking the cup launch those packets onto nearby surfaces while the fungus decomposes wood and mulch below.

- Very high
- Why interaction risk is low
- Wild fungi have dangerous look-alikes; do not eat or ingest specimens based on app identification.
Responsible observation
- Interior: Look for vertical fluting inside a mature open cup.
- Scale: Search closely because each nest is only about the size of a fingernail.
