Observation 20659: Heimioporus fruticicola (Berk.) E. Horak
When: 2007-03-24
Herbarium specimen reported

Notes: Peculiar spore ornamentation (rugose to rugoluse surface with cratered pits) is unique in the boletes so far. Current consensus using macro- & micromorphology (and some preliminary DNA data) indicate it is best placed in Heimioporus.
