Microporus xanthopus (Yellow-stemmed Micropore) is a common tropical, inedible polypore fungus identified by its thin, brown-zoned funnel cap and distinct yellow, central stalk. Found on rotting hardwood in Asia, Africa, and Australia, this saprotrophic, "spinning top" fungus decomposes wood and has potential for mycoremediation.
Key Facts about Microporus xanthopus:
Appearance: Features a 1–3 mm thick, funnel-shaped cap (up to 150mm wide) with concentric, brownish, or reddish-brown zones. The underside is white with very fine pores, often 8-10 per mm.
Stem: The yellow to golden-brown stem is central or off-centre and supports the cap.
Habitat: Commonly grows on dead hardwood logs and stumps in tropical forests.
Ecology: Saprotrophic, meaning it feeds on dead organic matter, contributing significantly to nutrient cycling.
Growth Rate: The stem can grow at an average rate of 1.3 mm per day.
Regional Names: Also known as the "golden-footed fungus" or "spinning top fungus".
Uses: While inedible, it is noted for its tough, woody, and persistent structure.
These mushrooms are often found in clusters and are known to be quite durable in humid, forested environments.
