Hypopitys lanuginosa — hairy pine-sap

Facts

Hairy pine-sap is found in southern New England in forests and woodlands, often where oaks (Quercus) are present. Pine-saps are mycotrophs, receiving nutrients via fungal mycelia rather than through photosynthesis. The stems of hairy pine-sap are often pink or red, distinguishing this species from yellow pine-sap, which has light brown to yellow stems. However, the two are often lumped together.
