Extract from Wikipedia article: Poronidulus is a fungal genus in the family Polyporaceae. It is a monotypic genus, and contains the single polypore species Poronidulus conchifer, found in North America. The genus was circumscribed by American mycologist William Alphonso Murrill in 1904. The generic name, which combines the Ancient Greek word πόρος ("pore") with the Latin word nidulus ("small nest"), refers to the superficial similarity of the cup-shaped Poronidulus fruit bodies with those of the genus Nidularia. A second species, Poronidulus bivalvis, found in Bogor, was placed in the genus by Franz Xaver Rudolf von Höhnel in 1914. The actual identity of this taxon, however, is uncertain.
Swedish: Poronidulus.
Poronidulus conchifer is a species of fungus that belongs to the family Polyporaceae. It is characterized by its thin, crust-like fruiting body that resembles a miniature ear or shell, typically 1-5 cm in diameter, with a wavy or lobed margin. The surface is often grayish-brown to tan, and the pores are small and rounded. In East and Central Texas, Poronidulus conchifer has been found growing on deciduous trees, particularly oak and elm, often on dead branches or trunks. It tends to fruit in the spring and summer months, typically from April to July. The fungus is considered rare to uncommon in the region, but can be locally abundant in areas with suitable habitat.

College Station, Texas, November 6, 2024Iron Bridge Trail, College Station, Brazos County, Texas, United StatesObservations of Poronidulus conchifer in East and Central Texas show that the fungus grows on various types of wood, including fallen twigs, branches, and tree limbs. The mushrooms were found in several parks and forests, including Bee Creek Park, Lick Creek Park, Sam Houston National Forest, and Huntsville State Park. They typically grow in brown cups with white extensions and have pores on the underside of their caps. The fungus was observed throughout the year, with sightings from March to November, and was often found on oak twigs and other deciduous wood. In some cases, the mushrooms were infected with a pinkish mold-like fungus, Hypomyces samuelsii. The spores of the fungus were also collected and observed. Overall, Poronidulus conchifer appears to be a common species in East and Central Texas, thriving on decaying wood in various environments.
