About Poronidulus conchifer (Schwein.) Murrill
The genus Poronidulus was originally described by Murrill with these characteristic features: the hymenophore is annual, tough, sessile, and grows on wood; it begins as a sterile, cup-shaped structure, with the fertile spore-producing portion developing later from this sterile base; the context is white and fibrous; the tubes are short with thin walls, and the tube mouths are polygonal; the spores are ellipsoidal, smooth, and hyaline. The cup-shaped fruit bodies of Poronidulus conchifer enable its spores to be dispersed when struck by raindrops, a dispersal mechanism that matches how bird's nest fungi spread their spores. P. conchifer is inedible.
