Remarks (public):Usually the lack of true skeletal hyphae will distinguish this species from S. paradoxa which also has fewer bulbous cystidia and somewhat larger spores.

Description:Schizopora radula (Pers.:Fr.) Hallenb., Mycotaxon 18:308, 1983; Polyporus radula Pers.:Fr., Syst. Mycol. 1:383, 1821. -Poria radula Pers., Obs. Mycol. 2:14, 1799; Polyporus versiporus Pers., Mycol Europ. 2:105, 1825.
Basidiocarps annual, resupinate ,adnate, effused, up to 5 mm thick; margin narrow anc white; pore surface yellowish cream, to ochraceous with a distinct pale orange tint; pore usually regular, angular, 1-3 per mm, dissepiments becoming lacerate and dentate witl age, on sloping substrata pores are more irregular; tube layer concolorous with port surface, up to 4 mm thick; context fibrous, thin and white.
Hyphal system monomitic; generative hyphae with clamps, hyaline, thin-walled tc slightly thick-walled and of regular width, branched, 2-4 µm in diam; hyphal ends in the trama often in part with thickened walls; hyphal endings in the dissepiments thin-wallec and usually covered with clusters of crystals.
Cystidia present as bulbous or capitate smooth hyphal ends in the hymenium, apex UT to 6 µm in diam.
Basidia suburniform with a slight constriction below the sterigmata, 4-sterigmate, 1520 x 4-5 µm, with a basal clamp.
Basidiospores ellipsoid, hyaline, smooth, thin-walled, negative in Melzer's reagent, 45 x 3-4 µm.
Cultural characteristics. See Hallenberg op. cit.
Sexuality. Heterothallic and tetrapolar (Hallenberg op cit.).
Substrata. Numerous hardwoods including Alnus, Betula, Carpinus, Castanea, Corylus, Fagus, Fraxinus, Populus, Quercus, Salix and Sorbus, more rarely collected on conifers like Abies, Juniperus, Picea and Pinus.
Distribution. Widespread in Europe, but seemingly more dominant in Central and Southern Europe than S. paradoxa. However, exact distribution is unknown since recently the two species were treated as one variable complex.
