Observation 119831: Entoloma stylophorum (Berk. & Broome) Sacc.
When: 2012-12-05
Herbarium specimen reported

Notes: This Entoloma sp. was found in subtropical forest just off Rt. 184 in Bosque Estatal de Carite in Puerto Rico’s Sierra de Cayey mountain range. I have seen more mature specimens in this exact location in past years but did not collect them. The pointy caps of the young basidiomata are very distinctive. The more mature specimen with pink gills was growing partially flattened under fallen wood. All were growing from soil/well decayed wood by fallen logs. The 20 spore size average was 10.3 × 7.2 microns with a Qm = 1.45. See photomicrograph for the 5-6 sided prismatic shape.

Danny, subgenus Inocephalus (Noordel.) seems very likely.

Thanks Richard!

Added a spore picture which I had failed to upload properly. No doubt it’s an Entoloma. Next project is to determine the species. I love these ghostly white guys.

very cool.
