The primitive liverwort Haplomitrium hookeri, only twice recorded previously in Eastern North America in 1917 and 1956, is reported from north-facing rocks at 1300m in the Tuckerman Ravine on Mt Washington, New Hampshire. Its occurence here on vertical wet rocks associated with the liverworts Cephalozia bicuspidata, Scapania undulata and Solenostoma hyalinum and the mosses Blindia acuta, Philonotis fontana, Pohlia nutans, Racomitrium fasciculare and R. heterosticum is very different from its ecology elsewhere in the northern hemisphere. The plants were sterile but had extensive subterranean leafless fungus-containing axes. Future molecular analyses are expected to reveal that the endophyte in the Mt Washington plants is a member of the Mucoromycotina, the earliest fungal lineage known to form associations with land plants.
Turnipseed Preserve in eastern Wake County, North Carolina was surveyed of its lichen diversity in 2009–2011. Specimens were collected from a variety of forest and rock outcrop habitats in this Outer Piedmont / Fall Line transitional zone. From 477 collections, 165 determined species representing 77 genera of lichens, including one lichenicolous fungus and one allied fungus, are reported as a checklist. Thirteen new state records were found, including: 1) three recently-described species: Acarospora janae, Lecanora appalachensis and L. nothocaesiella, and 2) Lichenotheliaceae, a family newly reported for North Carolina represented by the lichenicolous fungus Lichenostigma cosmopolites and the “border-line lichen” Lichenothelia sp. Turnipseed's lichen biota was compared to those of other surveyed areas in North Carolina and South Carolina via Jaccard analysis, detecting a distance decay of similarity. Suggestions for further research are offered.
