Who: zaca

No specimen available

Notes:
See the notes of Observation 277184.
I knew that these specimens were special and I remembered to observe some similar before (see Observation 120318), but ignored its classification. Now Dr. Henry Beker did it for me: Hebeloma porphyrosporum, which is characterized by the pink to violet staining of the hymenium, at least at maturity.
This was the last of three specimens found in consecutive days at the same zone of the park, having a typical mediterranean habitat, dominated by Quercus suber with some other oaks as well and some scattered pines.
