Observation 220587: Armillaria (Fr.) Staude

When: 2015-10-24

Collection location: Ricketts Glen State Park, Pennsylvania, USA [Click for map]

Who: Dave W (Dave W)

No specimen available

Same exact location as obs 220216 , eight days later.

Lack of ornamentation on the cap surface and adnexed gill attachment sent up a red flag while gathering edible popinkies. Otherwise, these look like the long brown ones seen in obs 220216.

Spore print white.

Spores viewed in profile with prominent apiculi. Spore size quite variable. Some approached 12 mu in length, well above the reported maximum for gallica.
