Observation 54381: Sphaerophorus venerabilis Wedin, Högnabba & Goward

When: 2010-09-19

Collection location: Glacier Peak Wilderness, Washington, USA [Click for map]

Who: Jason Hollinger (jason)

No specimen available

in rainforest at ~4000’ near Sitkum Creek

The key I have access to distinguishes two epiphytic species of Sphaerophorus:

S. venerabilis — main stems irregularly dimpled; dense clusters of 3rd-order branchlets confined to base if present; black pycnidia abundant
S. tuckermannii — main stems at most weakly dimpled; dense clusters of 3rd-order branchlets scattered throughout; pycnidia sparse

I’ve never seen S. venerabilis before, but thought that this looked different from the usual material of S. tuckermannii (sparser “foliage” and black dots).
