Dicranella schreberiana var. robusta, Barbula indica, and Tortella inclinata are newly reported for the bryoflora of Pennsylvania. The occurrences of Andreaea crassinervia and Seligeria pusilla in the Commonwealth are confirmed.

A checklist of lichens collected in the Big Horn Mts. in Wyoming in 2007 is presented. There were 202 species found as a result of 1400 collections at 40 localities within the Bighorn National Forest. The lichen flora is similar to those of the Black Hills and Rocky Mountains, but some unusual species were found, including Teloschistes contortuplicatus and Anaptychia ulotrichoides.

Fifteen Sphagnum species were collected from wet drainages associated with 19 abandoned coalmines in western Pennsylvania: S. affine Ren. & Card., S. bartlettianum Warnst., S. centrale C. Jens., S. cuspidatum Hoffm., S. fallax (Klinggr.) Klinggr., S. fimbriatum Wils., S. isoviitae Flat., S. lescurii Sull., S. magellanicum Brid., S. molle Sull., S. palustre L., S. papillosum Lindb., S. russowii Warnst., S. subtile (Russow) Warnst., and S. teres (Schimp.) Ångstr. The most common species was S. fimbriatum. All are common in the region, except S. molle, which may represent a disjunct population.

Erioderma pedicellatum (Hue) P.M. Jørg is a globally rare, foliose cyanolichen known from Scandinavia and southeastern Canada. In August 2007, several thalli of E. pedicellatum were collected in Denali National Park and Preserve on the south side of the Alaska Range, Alaska, USA. Subsequently, several additional thalli were observed in nearby Denali State Park. Together they represent the first report of E. pedicellatum within the United States and western North America and mark a major range extension for one of the most rare and endangered lichens in the world. The existence of a third global population center raises intriguing questions about the nature of the genetic relationships among eastern North American, western North American and Scandinavian populations.

109 species of lichens and 9 lichenicolous fungi are reported from Point Loma from the Cabrillo National Monument and adjoining Navy property in the Point Loma Conservation Area. Porpidia soredizodes (Lamy ex Nyl.) J. R. Laundon is reported new for California.
