We identified 68 bryophytes (4 liverworts, 64 mosses) during three days of sampling five Friends of Sax-Zim Bog (FOSZB) properties and five additional sites within the surrounding 147,000-acre Sax-Zim Bog Important Bird Area in St. Louis County, Minnesota. The landscape types surveyed are loosely categorized as upland, forested wetland, moderate-rich fen, poor fen, restored fen and bog. In total, this survey added 50 species (3 liverworts, 47 mosses) to a previous FOSZB bryophyte species list for a total of 78 bryophyte species (4 liverworts, 74 mosses) documented in the greater Sax-Zim Bog region. Over 20% of the bryophytes found were in the genus Sphagnum. Our updated list of common bryophytes will be used by FOSZB staff for educational purposes to inform FOSZB visitors about local bryoflora.

Bryoerythrophyllum wallichii previously restricted to high elevations in Asia has been found on Baranof Island near Sitka, Alaska.

Twenty-five North American lichens are issued in Fascicle VIII of the “Anderson and Shushan: Lichens of Western North America” series, numbers 176–200. This fascicle is comprised of material representing specimens from the Rhizoplaca melanophthalma aggregate, including the vagrant taxa R. arbuscula, R. haydenii, and R. idahoensis; two collections representing unattached forms in the R. porteri group – R. melanophthalma ssp. crispa and an erratic form of R. porteri; and two umbilicate saxicolous taxa, R. robusta and R. shushanii, the former described as new to science here. We also provide the first morphological description for R. shushanii, a species that was initially described based on diagnostic DNA sequence characters.

The recently described species Nephroma orvoi is part of the Nephroma parile complex. Both species are generally medium to dark brown, with rounded, smooth to distinctly foveolate lobes bearing sorediate to isidiate propagules. The best distinguishing character morphologically is the location of propagule formation. On N. orvoi they originate laminally while on N. parile they originate marginally. However, TLC provides the most accurate identification results, as the two species differ in terpenoids. We examined 76 presumed N. parile herbarium specimens from OSC, both morphologically and by TLC, and found that N. orvoi and N. parile have overlapping ranges in western North America and occur in similar boreal and temperate forest habitats.

Two species of Bryaceae are reported as new to the Flora of North America region. Bryum austriacum Köckinger, Holyoak & Suanjak is newly reported here from North America from the White Pine Hollow State Preserve in Iowa and is transferred to Plagiobryum Lindb. This represents a major range extension from the European Alps. Bryum biforme R.S. Williams is newly reported here from North America from Arizona at a high elevation site on Rincon Peak and is transferred to Rosulabryum J.R. Spence. The related Mexican species Bryum richardsii Sharp is also transferred to Rosulabryum. New state records include Gemmabryum exile (Dozy & Molk.) J.R. Spence & H.P. Ramsay from New York, Brachymenium mexicanum Mont. from New Mexico and Texas, G. vinosum J.R. Spence & Kellman from Idaho, Imbribryum torenii J.R. Spence & Shevock from New Mexico, Plagiobryoides renauldii (Röll ex Renauld & Cardot) J.R. Spence from New Mexico, Ptychostomum inclinatum (Sw. ex Brid.) J.R. Spence from New Mexico, P. marratii (Hook. & Wilson) J.R. Spence from Alaska, and P. weigelii (Biehler) J.R. Spence from New Mexico. The new combination Rosulabryum sanguilentum (Renauld & Cardot) J.R. Spence & Brinda is made, replacing R. gemmascens (Kindb.) J.R. Spence.
