Forty moss taxa comprising 15 families were identified from 17 abandoned coalmines or exposed coal seams in western Pennsylvania. Aulacomnium palustre, Ceratodon purpure us, Dicranella heteromalla, and Pohlia nutans were most frequently collected. Pohlia nutans was observed in the harshest environments. Noteworthy, less frequently collected species included Barbula convoluta, B. indica, and Didymodon tophaceus.

Thirteen lichen species are reported new for Washington State: Agonimia tristicula, Arthonia macounii, Fulgensia subbracteata, Hypocenomyce anthracophila, Lecanora albellula, Lecanora hybocarpa, Leptogium schraderi, Massalongia microphylliza, Physconia leucoleiptes, Rinodina calcigena, Solorina bispora, Thyrea confusa, and Toninia tristis var. scholanderi. These reports are from seven localities, mostly from the drier, eastern counties. I highlight the need for statewide conservation assessment of these species.

Trichostomum crispulum has been found in Oregon on Medford BLM lands. It is newly documented to this state. During past surveys, it has been difficult to distinguish due to its similarity to other mosses like Weissia controversa.

In 2007 and 2008, ten mosses and two liverworts were used by Carolina chickadees (Poecile carolinensis) to construct two nests. Dominant bryophytes used in construction were Frullania eboracensis and Platygyrium repens. Bryophytes were not randomly selected, and all taxa were corticolous. Carolina chickadees may be selecting Frullania eboracensis for chemical properties.

Zygodon apiculatus Redf. is reported for the first time from Pennsylvania. The species is otherwise known from Iowa, Missouri, and North Carolina.

Sphaerocarpos michelii is newly reported for Illinois. This report extends the range of the species and represents the northern most occurrence in North America.
