Description:
Diagnosis: Pileus viscid or dry, tomentose to subtomentose, microscopically a trichodermium or ixotrichodermium, sometimes with appendiculate remnants at margin. Context white or yellow, unchanging. Hymenophore tubulose, adnexed, white at first, pinkish flesh colored to brownish pink with maturity (rarely yellow), sometimes staining light brownish to pinkish brown. Stipe central, pruinose to alveolate-reticulate, dry or sometimes glutinous-viscid, not staining or developing stains in situ from aging; basal mycelium white. Spores vinaceous pink in deposit, obscurely pitted to pitted to sinuous pitted, sometimes equatorially verrucose, amygdaliform to elongate-fusoid, inamyloid or dextrinoid. Hymenial cystidia usually present. Clamp connections absent. KOH & NH4OH reactions negative.
Registration number: MB17141
Type species: Porphyrellus dictyotus Boedijn, Persoonia 1: 316. 1960.
Ectomycorrhiza: Pinaceae, Fagaceae, Myrtaceae, Dipterocarpaceae, Casuarinaceae.
