Hygrophorus sp-IN07 was found growing from soil in low mixed Oak–Hickory woodland near a creek in Indian Cave State Park in eastern Nebraska. It was originally collected from southern Indiana. Nearby trees included American Hophornbeam (Ostrya virginiana), American Hackberry (Celtis occidentalis), Red Mulberry (Morus rubra), Northern Red Oak (Quercus rubra), American Linden (Tilia americana), and Shagbark Hickory (Carya ovata).

Fruiting bodies have whitish caps with a light tan center and a sticky surface when wet. Gills are light tan and waxy. The stem is white, slightly discoloring tan with handling or age. The spore print is white.
