Cinnabar Polypore Fruiting

cinnabar polypore WITH LABEL 082It is very hard to miss a fruiting Cinnabar Polypore (Pycnoporus cinnabarinus) fungus due to its electric red-orange coloration (on both upper and lower surfaces). It is in a group of fungi known as polypores, which usually grow on dead trees, are shaped like shelves, not umbrellas, and have many tiny holes, or pores (as opposed to gills), on their underside, where the spores develop. Cinnabar Polypore is also known as White Rot Fungus, as it breaks down lignin and cellulose in dead trees, causing the rotted wood to feel moist, soft, spongy, or stringy and appear white or yellow. Look for it on dead cherry, birch and beech trees.

    • I’m afraid it’s inedible, Craig.

    Doesn’t look edible to me, you?

    Carpe diem, Jennifer
