Japewiella dollypartoniana
A lichen species named for country singer Dolly Parton.
Japewiella dollypartoniana is a crustose lichen belonging to the Lecanoraceae family. Its range covers much of the Appalachian Mountains in eastern North America, with additional reports from Ontario, Canada. This species typically inhabits tree branches, sapling stems, and shrub stems at middle to high elevations.
The lichen was formally described as new to science in 2015 by Jessica Allen and James Lendemer. The type specimen was collected in the Joyce Kilmer-Slickrock Wilderness area of North Carolina’s Nantahala National Forest, where it grew on an exposed rock within a heath bald community dominated by ericaceous shrubs like Rhododendron, Vaccinium, and Kalmia, at an elevation of 5,160 feet. Its specific epithet honors Dolly Parton, described by the authors as a native of the southern Appalachians and one of the most famous country singers of all time.
The thallus is crustose, roughly circular, and greenish-gray to brown, measuring 2–6 cm across, though neighboring thalli sometimes merge into larger patches. Its surface bears soralia that break through, releasing discrete spherical soredia 10–50 μm in size. Apothecia are rarely seen, documented only from a few populations on Haoe Mountain. The lichen produces norstictic and connorstictic acids as secondary chemicals.
Another sorediate crustose lichen, Lambiella fuscosora, also produces norstictic acid. In 2017, sterile material from Eagle Hill in Maine and Ontario was initially reported as Lambiella fuscosora new to North America, but re-examination showed it was actually Japewiella dollypartoniana, thereby extending this species’ range into Canada.

Lore & Background
The lichen was formally described as a new species in 2015 by Jessica Allen and James Lendemer. The type specimen was found in the Joyce Kilmer-Slickrock Wilderness area of Nantahala National Forest in North Carolina, growing on an exposed rock in a heath bald community dominated by ericaceous shrubs such as Rhododendron, Vaccinium, and Kalmia, at an altitude of 5160 ft. The specific epithet honors Dolly Parton, described by the authors as 'one of the most famous country singers of all time and a native of the southern Appalachians'.
Japewiella dollypartoniana is a crustose lichen with a more or less circular greenish-gray to brown thallus measuring up to 2–6 cm, although sometimes neighboring thalli coalesce to form larger aggregates. The thallus features soralia that break through the surface, comprising discrete spherical soredia that are in the size range 10–50 μm. Apothecia have been rarely documented in this species, known only from a few populations on Haoe Mountain. Secondary chemicals found in the lichen are norstictic and connorstictic acids.
The species Lambiella fuscosora is another sorediate crustose lichen that produces norstictic acid. In 2017, it was reported as new to North America based on sterile material from Eagle Hill in Maine (United States) and Ontario (Canada). Re-examination of the specimens showed that they were in fact Japewiella dollypartoniana, extending the range of this lichen to Canada.
Reader's Guide
Japewiella dollypartoniana holds significance as a lichen species that bridges taxonomy, biogeography, and cultural recognition. Its description in 2015 added a new member to the Lecanoraceae family, and its naming after Dolly Parton highlights the connection between Appalachian biodiversity and regional heritage. The species is widely distributed in the Appalachian Mountains and was later confirmed in Canada after a re-examination of specimens initially misidentified as Lambiella fuscosora. This correction extended its known range and underscored the importance of careful taxonomic review. The lichen's crustose growth form, sorediate reproduction, and production of norstictic and connorstictic acids contribute to its ecological role on tree branches and shrub stems at middle to high elevations. Its rarity of apothecia, documented only on Haoe Mountain, adds to its biological interest. Japewiella dollypartoniana serves as an example of how scientific discovery can intersect with popular culture, while also advancing understanding of lichen distribution in eastern North America.
