When: 2013-06-21

Collection location: Seven Tubs Natural Area, Pennsylvania, USA [Click for map]

Who: Dave W (Dave W)

Specimen available

My interpretation of the unusual basal structure is an elongated internal limbus. The marginal striations are very faint, perhaps due the changes in the weather.

Local levels of humidity vary greatly, and I think this may be the reason why marginal striations seem to sometimes appear on types for which this is not a typical trait, and fade on types for which this should be a strong macro-character.

Hemlock mixed with birch and other hardwoods.

Material is being dried.
