[1] Molecular analysis of the genus Phylloporus shows that P. leucomycelinus and a group of phylogenetically related species (P. bellus, P. rhodoxanthus, P. dimorphus, and P. castanopsidis) form a well-supported clade.

[3] The cap is initially convex before flattening out in maturity, sometimes developing a shallow depression; it reaches a diameter of 4–8 centimetres (1+1⁄2–3 inches).

[1] The fruit bodies of P. leucomycelinus grow scattered or in groups on the ground in deciduous forests, usually near beech and oak trees.

Found in North America, its range includes eastern Canada south to Florida, and west to Michigan.

[4] Fruit bodies can be used in mushroom dyeing to produce beige, gold, or greenish-beige colors, depending on the mordant used.
