in diameter, but they can be as large as 10mm) mostly on the dung of horses, cows, and donkeys in pastures. Te fruitbody is actually a stroma, featuring a dark brown bowl- or cup-shaped base and a flat, beige top that is punctured by tiny irregular sized pores (ostioles). Digging into the substrate will reveal a short or often long stalk. Sliced in half, a fruitbody reminds of Xylaria; the flesh is white, black spores are produced in perithecia embedded just under the stromal surface. Croatian ascomycetologist and friend
of FUNGI, Neven Matoĉec, points out that Poronia species (P. oedipus, P. erici, and P. punctata) are distinguished from one another by size of stromata and ascospores, as well as substrate (dung of the rabbit, goat, sheep and various marsupials). In Europe, Poronia species are becoming rarer and potentially endangered as a result of changing agricultural practices. Fewer and fewer livestock owners are pasturing their animals outdoors which has the result of diminishing habitat for this coprophilic fungus.
