porcelain fungus

i do not really recognize this one well. as you can see, at least the bigger one should be matured and have released his spores. while there is no discoloration (from sporepowder), i will suspect the spores where white, because the cap is wrinkled and seems dry- i suspect it has dehydrated; the base of the stem also looked like it is hardend. THEN- i found no other white;whitespored;wet/slimy cap; tree growing mushroom than the "oudemansiella mucida". and 5 meter further where standing some definitly real "mucidas" Therefore i suspect: this is an a little bit misformed/mutated "Porcelain Fungus"
