Je ne sais pas à quoi ressemble Schizopora radula. En fait je ne l'ai jamais observé, la dizaine de micro m'ayant toujours donné des
spores compatibles avec Schizopora paradoxa. C'est donc une chose rare, du moins dans mon coin. Par contre j'ai pu voir la grande
variété des hyméniums de Schizopora paradoxa et suis assez convaincu de l'impossibilité de trancher entre les deux d'un point de
vue macro.

Remarks
The distinction of the species Sch. paradoxa and Sch. radula is very difficult. Hallenberg (1983) however was able to prove their strict separation as biological species by testing their compatibility. The micromorphical differences of both species is hard to be comprehended only by herbarium specimens. The distinction whether iricoid or poroid is also very uncertain. There exist transitional forms of both basidiocarps. It is my opinion, that the best mark of distinction is the colour of the basidiocarps. Sch. paradoxa is always coloured white to yellowish and Sch. raula always has an orange touch. Sch. paradoxa moreover has spores, that are a little bit longer than the others. In southern areas with a warmer climate in addition Sch. flavipora can be found. But this species can be distinguished very easily from Sch. paradoxa and Sch. radula by their cystidia.
