Confidence: I'm as sure as I can be.
Notes: Arboreal species. Past its best at time of observation and very soggy. Rusty orange cap. Crowded, adnate gills concolourous with cap. These mushrooms stained my hands, and everything they came into contact with, orange.
Dense clusters of tiered caps up to 30 cm or so in diameter. Ochre stipe with ring.
