Little Nest Polypore

Poronidulus conchifer


The mature fruiting body composed of a ‘cup-and-saucer’ structure. The cap (saucer) is approximately 1 inch diameter, semicircular, bald. The ‘nest’ (‘cup’) is nestled on the cap at the attachment point; approximately 0.5 cm diameter and cup-shaped, bald. The flesh is tough. The pore surface is white with large, circular pores; 2-4 pores/mm. In this observation, the nests (cups) remain after the caps (saucers) have fallen off.


Growing on dead branch of hardwoods tree (species unidentified, but not elm). Poronidulus grow on hardwoods, primarily elms. However, elms are rare in this area.


Photographs of entire Poronidulus conchifer bracket and nest: It is unusual to find the entire fruiting body. Usually the cups (nests) are all that remain. Additional photos/discussion at:
