Many lichen cannot be named unless they are observed when in a fertile state. One common crustose lichen in the Appalachian region has been observed for many years but never seen reproducing. That changed when a large number of fertile lichen were found on the top of Hangover Mountain in western North Carolina. They were common in many areas but this was the first time anyone had seen them in a fertile state. These lichen were then named….for Dolly Parton. Japewiella dollypartoniana now had a formal name and characteristics to identify it in the future.
Jessica L. Allen and James C. Lendemer, who made the discovery and published their findings in 2015, described the lichen as “….distinguished from other species of Japewia and Japewiella by its sorediate thallus and production of norstictic acid….”. There is more technical description of the lichen that follows.
Japewiella dollypartoniana is described as new to science based on material from the Appalachian Mountains and adjacent regions of the Atlantic Coastal Plain. It is distinguished from other species of Japewia and Japewiella by its sorediate thallus and production of norstictic acid. Placement in Japewiella is supported by characters from fertile populations discovered in the Unicoi Mountains of western North Carolina which have apothecia that resemble those of Japewia tornoënsis (Nyl.) Tønsberg but differ in having a well-developed proper exciple and ascospores without a thick, gelatinous sheath.
This gorgeous lichen was found by Julie Hoel in St. George Island State Park, off the panhandle of Florida, late this winter. It is growing in a slash pine forest, on sandy ground. Thanks Julie for sharing this.
We don’t see this lichen in the Kickapoo, but I remember similar lichen in the jack pine forests of the Wisconsin River valley when I was a child. The oak and jack pine forests from Mazomanie, Arena, Spring Green, and Lone Rock area were filled with mosses and lichens. The ground was covered and they hung on tree branches. It was a wonderland of shapes and colors. As a child I knew it was a magical place and I spent many hours there but had no way to know what I was seeing. Now those forests are mostly gone, covered with irrigated, industrial scale, sprayed crops. The lichen are in retreat and mostly absent. With them went the diversity of birds, amphibians and plants that made up that fragile and beautiful land. In those days only a child would recognize the beauty in that dry, unassuming landscape but now some of the goat prairies and grasslands are being restored, and there are remnants of sandy jack pine forests in the river valley.
Julie’s Florida lichen picture inspires me to explore some of the Wisconsin River valley forests that are left to search for my lichen and moss friends from years ago.
I’ll let you know what I find!

I have had the great fortune to be travelling in Australia since early December. In the midst of visiting friends and family I have also been in search of lichens.
Discovering lichens on a rusty steel hull of a 100 year old gold digging machine in a dried up river bed has been the greatest surprise to me.
The most noticeable difference from lichens at Kickapoo Valley Reserve has been the extreme absence of tree lichens in many areas. While considering this, it clicked that over half of the trees in Australia being eucalyptus and melaluca all decortify every year (lose their bark). Lichens being slow growing communities are not so partial to growing on constantly changing strata.
I was sure I would find many in the damp sub-tropical forests, and farmlands, but was really surprised to discover them in what I would have considered inhospitable locations: dry river beds with dead trees and running rampant across boulders washed by ocean tides and blasted by hot sun. Some of these locations have been in drought for over 7 years. Seasides, bereft of most plant life and old tombstones in dry country graveyards, were populated with many different communities of lichens. I do not know many of their names, but it has been a delight to discover their adaptability.
The colors are quite spectacular, particularly in the moist warm areas of the eastern coast.
Paying attention to lichens on this journey to Australia has added a new dimension to my journey, as I not only witness the drama of this landscape in its large breathtaking vistas, but also able to recognize the miniaturized vistas and complexities of lichen communities in very diverse landscapes.
It is a new depth of exploration and has expanded my vision of forests, seascapes, and dry farms and eucalypt forests.
I wonder what lichens exist in the dry moonscape of Cooper Pedy or the towering red rock of Uluru and the Olgas all places I had the opportunity to travel to in the past, but did not know enough to seek them out.
Im “lichen” these lichens as they are adding a new dimension to my journey.
