Excellent information and addition to the observation. I recently purchased Lichens of North America and am still pretty new to them- so your info is coming in very handy along with Jason H. You’re a great resource >.<

Nice observation! … and thanks to Jason for a quick identification. Here is a bit of background information: There are two epiphytic species of Sphaerophorus in North America, S. tuckermanii and S. venerabilis, and in fact S. venerabilis was just described as a new species in 2009. Both occur near your locality. Here is the relevant part of the key from Wedin, Mats, Filip Högnabba, and Trevor Goward (2009):

1a. Main branches slender with abundant dense clusters of brittle coralloid branchlets; apothecia comparatively uncommon; epiphytic … S. tuckermanii
1b. Main branches sturdy with no or comparatively few clusters of coralloid branchlets; … epiphytic in old-growth forests (rare on the ground); medulla lax; main branches +/- matte, strongly foveolate/scrobiculate [= with irregular depressions and ridges]; apothecia usually abundant; coralloid branchlets absent or very sparse … S. venerabilis

McCune and Geiser (2009, pp.) provide a similar key and photos of both species. See also our MO page on Sphaerophorus of North America
