When: 2015-03-02

Collection location: Sendero Macuco, Parque Nacional Iguazú, Misiones, Argentina [Click for map]

Who: Danny Newman (myxomop)

No specimen available

Almost too sturdily constructed to be a Pleurotus, assuming that Pleurotus is not allowed to house any dimitic or trimitic species. If not Pleurotus, then Panus. The purple seems diagnostic. Similar or same collected at the Centro de Investigacion Antonia Ramos as well (Observation 231289).

Substrate: on downed, corticate, ~20cm diam. log.

Habitat: public park trail

Ecoregion: Alta Paraná Atlantic Forests (NT0150)

Collectors: E. Grassi, D. Newman, V. Silva & V. Vignale

Panus hirtiformis

type is from Belize. If this is the same taxon I have found several times in Puerto Rico, which I believe it is, the violaceous tones will soon disappear like many other Panus spp. More often than not I find these are already white or pale ocraceous, and sometimes there is a young specimen nearby with the purple tone still intact. The purple color is not mentioned in the description because it appears to be based on one collection or perhaps just one mature individual. I’m sure if you scope this you will see this matches very well with the full description of the taxon in Pegler with the small spores and abundant gloeocystidia. It is dimitic with unbranched skeletal hyphae and uninflating generative hyphae
