The Lacawac Sanctuary is a non-profit nature and environmental research and education center located in the Pocono Mountains of northeastern Pennsylvania. An inventory of the bryophytes was conducted in the fall of 2015 to increase understanding of the rich bryoflora of the sanctuary and the surrounding region. A total of 105 mosses and 23 liverworts were collected and identified. Of these, 52 mosses and 15 liverworts are reported as new county records. A single new state moss record is documented.

In an effort to protect a forest on provincial land near Goldsmith Lake in Annapolis County, Nova Scotia, from timber harvest operations, a group of citizen scientists began documenting the biodiversity of the area. In December 2022, the group invited Dr. Steven Selva, a lichenologist specializing in calicioid lichens and fungi, to visit and teach them how to locate and collect calicioid specimens. We found 27 calicioid species, one of which was new to the Maritimes, providing additional evidence that the forest is rich in biodiversity and that the areas recognized as old-growth were larger than the provincial government had previously realized.

We provide the first North American report of the lichenicolous fungus Pronectria fragmospora. Based on multigene phylogenetic analyses we found this species to be nested within the genus Trichonectria and the new combination Trichonectria fragmospora is proposed. We provide a description and photos of the North American material on Evernia prunastri and a phylogenetic tree showing its placement within the genus. We also compare this species to related species of Trichonectria and similar species of Pronectria.
