Assessment Notes

Taxonomic notes

Lenzites stereoides has a pileus white to pink and finely adpressed, velvety in narrow zones. The context is white to faint pink. The hymenial surface is most variable, from poroid with a few split pores, semi-daedaloid or labyrinthic, with long radiating dentate lamellae to deeply split flattened teeth, to purely hydnoid with long and almost cylindrical spines. The hyphal system is trimitic with hyaline binding hyphae, quite sparsely branched and long hyaline skeletal hyphae, endings of both these types project into the hymenium as cystidial organs often with scattered small crystals. The generative hyphae is thin to thick-walled and with clamps at the septa (Ryvarden 1974).
