Observation 88015: Cliostomum griffithii (Sm.) Coppins

When: 2012-02-19

Collection location: Spencer Island, Snohomish Co., Washington, USA [Click for map]

Who: Richard Droker (wanderflechten)

Specimen available

Notes:
on bark of dead branch Alnus Rubra

this is an area of relatively low air quality (near interstate highway and agriculture)

Jason Hollinger suggested C. griffithii – thanks! Although the morphology really fit, initially this seemed problematic because the 1st section was polarization negative, the spores were somewhat large (17 × 4) and most were 2- and 3-septate.
