Remarks (public):Phlebia aurea lacks cystidial elements, but in agreement with Eriksson & Ryvarden (1976) we have seen in one collection (Bernicchia 7969) projecting hyphal ends not only in the aculeus end, that resemble cylindrical cystidiols with obtuse apex. They appear both isolated or forming small fascicles near the aculei apex.
