Observation 11522: Scleroderma cepa Pers.

When: 2008-09-24

Collection location: Southeast Portland, Multnomah Co., Oregon, USA [Click for map]

Who: Daniel B. Wheeler (Tuberale)

No specimen available

While this may look like Scleroderma citrinum, it is S. cepa. The gleba is purplish, very hard, and the peridium is 3-5mm thick, with a halo of pink just inside the peridium near the gleba. The areolate appearance of the upper peridium is likewise confusing, since it usually indicates S. areolatum (see other observervation for this date). The key quality is the gleba in this species is quite solid/hard when young (as this specimen is). It helps to have been collecting at the same site for the past 20 years, too.
