Antrodiella

Antrodiella is a genus of fungi belonging to the family Polyporaceae, commonly known as the *polypores* or *conks*. These fungi are primarily saprotrophic, meaning they decompose dead wood, though some species may also exhibit weak parasitic behavior on living trees. The genus was established by mycologist Rolf Singer in 1948, and it currently includes around 20 recognized species, though taxonomic revisions may alter this number.

Antrodiella species are characterized by their hard, woody basidiocarps (fruit bodies) that often persist for several years. These fruit bodies typically grow on coniferous trees, particularly in temperate and boreal forests. The pores on the underside of the cap are usually angular or irregular, and the coloration can range from pale to dark brown or black. Some species produce a resinous or gummy exudate when fresh.

Ecologically, Antrodiella fungi play a significant role in forest ecosystems by breaking down lignin and cellulose in dead wood, facilitating nutrient cycling. While not typically considered edible, some species may be consumed in certain cultures, though they are generally avoided due to their tough texture and potential toxicity. A few species, such as *Antrodiella semisupina*, have been studied for their antimicrobial properties.

Identification of Antrodiella species often relies on microscopic examination of spore prints and hyphal structures, as macroscopic features can be similar across species. Proper identification is important, as some look-alikes may be toxic or harmful to trees. Conservation efforts focus on protecting their natural habitats, particularly old-growth forests where they thrive.
