Voucher specimen: Tennessee, Franklin County, Sewanee, Beckwith’s Point Trail, 21 Mar 2009, Chris Parrish 0025, det. Gary Perlmutter (NCU)

Common name: powderhorn cladonia

Note added 28 Apr 2009:

Identification: Powderhorn cladonias collected on Beckwith’s Point Trail (near the site of photo 32076, but not the same material seen in that photo) were determined by Gary Perlmutter at the UNC Herbarium to represent Cladonia ochrochlora, rather than Cladonia coniocrea. In the Ozarks, C. ochrochlora is the more common species (Harris and Ladd, 2005, p.101). Casual observations here at Sewanee suggest a range of variation in the local powderhorns. There may be more than one taxon involved.
