Ischnoderma resinosum
Resinous polypore is a shelf fungus that shows up on dead or decaying hardwood in the Northeast, usually late enough in the season that it feels more autumnal than the brighter summer bracket mushrooms.12 A New Hampshire herbarium record places it on decaying hardwood at Ashuelot Pond, which fits the way it tends to appear here: attached to wood rather than emerging from soil, and often encountered while looking for other fall mushrooms.2
Young specimens are the useful ones as food. University and herbarium sources describe the fruiting body as fleshy when young and hard and brittle with age, which matches the practical dividing line in the kitchen: early growth can be tender enough to cut and cook, while older shelves quickly become too tough for ordinary eating.13 The fungus is also notable for a strong anise-like or candy-like aroma, and food-chemistry work on the species has treated that smell as one of its defining culinary traits rather than a minor curiosity.13
That combination of firmness, aroma, and eventual toughness is exactly what makes resinous polypore interesting in this notebook. It can read a little like a wild counterpart to oyster mushrooms or even a softer Chicken of the Woods at the right stage, but it is better thought of as a bracket fungus whose edible window is brief and specific. Once it passes that stage, the texture is less suited to direct cooking and more useful for ideas like Resinous Polypore Garum, where time, salt, and enzymes can pull flavor out of a mushroom that no longer wants to be eaten as a slice.
