Fungus · GBIF taxon 5246344
yellow stemmed micropore
Microporus xanthopusAlso known as Yellow-stemmed Micropore, Yellow-stemmed Polypore, Yellow-stalked Micropore
Yellow stemmed micropores form thin, funnel-shaped brackets with concentric bands of chestnut, tan, and pale cream atop a distinct yellow stem. Anchored to fallen branches and rotting logs in tropical forests across Asia, Africa, and Australasia, these white-rot fungi play an essential role in breaking down tough wood lignin. The underside features remarkably tiny pores that release spores into humid rainforest air currents.

Interaction riskLow

- High
- Very high
- Why interaction risk is low
- Many wild mushrooms have toxic look-alikes; never eat wild fungi based on app identification alone.
Responsible observation
- Check the Stem: Look for the distinct yellow stipe anchoring the thin bracket cap to decaying wood.
- Inspect the Underside: Examine the pore surface with a hand lens to appreciate the incredibly tiny pore openings.
- Leave in Place: Leave fruiting bodies intact to allow spore dispersal and continued wood decomposition.
