Observation 54923: Hypsizygus ulmarius (Bull.) Redhead

When: 2010-10-05

Collection location: Pembroke, Ontario, Canada [Click for map]

Who: Paul Derbyshire (Twizzler)

No specimen available

Found in moist hardwood woods (absolutely zero conifers) fairly close to the Ottawa River, northwest of downtown Pembroke.

There were several of these growing on several close-together trees in one small area. Largest 6-7cm wide. All parts look white, else I’d have suggested Pluteus due to the free gills.
