Brief Description: [See More | Edit]

Ischnoderma resinosum (Fr.) Karst. is a polypore common in the North American hardwood forests. It is easily identifiable upon a detailed inspection. When fresh, it is a characteristically soft polypore with a notably velvet like texture on the top portion of its cap. The vast majority of specimens are fan shaped on decaying hardwoods with caps that can range from 3-10”. The velvety top surface has notable zones/rings that radiate outward from the point of attachment. Young specimens are distinctly moist and will seep water when crushed. Distinct from other polypores, Ischnoderma resinosum is very fleshy especially when young. The spore bearing underside is white but quickly turns brown and bruises with slight pressure. As the specimen becomes larger and ages, it quickly becomes tough with a leather like texture similar to other polypores.
