White fungus (?)
The glossy, heart-shaped leaves of this 6-10 in. The three lower petals are somewhat hairy. The erect flower stem droops slightly, as if bending its head toward the ground.
The leaves are alternate, pinnately compounded, 9 to 14 inches long, with 7 to 9 serrate, lanceolate to obovate-lanceolate leaflets, rachis is stout and very pubescent, green above and paler below.
The leaves are palmate, 8–16 cm long and 6–12 cm broad, with deep angular notches between the five lobes.
The trees are flexible, bluish-green, finely serrated, and 5–13cm (2.0–5.1 in) long, attached with slender cones.
The leaves are simple, alternately arranged, asymmetrical, unequal at the base (the side nearest the branch the largest), 10–15 cm (can grow up to 25 cm) long and broad, with a long, slender petiole.
Just hatched, making its way to the pond.
This one is odd in that it's missing one orange spot, but I think it's still polyxenes.
