Judy and Ron Robertson were outstanding amateur lichenologists in California. Their huge lichen collection (over 8,500 collections) was donated to the University of California Herbarium after their deaths. This article describes 36 unusual lichens that they collected in California, together with their provenance, many of them extremely rare or new to the California flora.

The history and current status of the lichen collections at the Biodiversity Institute of Ontario Herbarium (OAC) are presented, including a list of all taxa. Seven hundred and seventy-three lichen and allied fungi in 239 genera have been deposited into the herbarium since 2005.

Frullania cuencensis is newly reported from Texas, extending the documented range of this species north of Mexico to the United States. The species can be separated from F. riparia by its inflated, galeate lobules that have triangular proximal portions; subulate styli; and entire, somewhat recurved ventral leaf margins. Frullania mexicana is taken out of synonymy and confirmed from Arizona and New Mexico, as well as newly reported from Texas. It differs from both F. inflata and F. tetraptera in having differentiated marginal/median cells of the leaf lobe and an obovoid perianth with eight or more keels. Other distinctions between F. inflata and F. tetraptera are presented. Frullania mexicana has been confused and overlooked in the United States with several literature reports of F. inflata and F. pluricarinata specimens from Arizona and New Mexico belonging to F. mexicana.

Ochrolechia brodoi Kukwa is reported as new for North America and Alaska. Other corticolous species of Ochrolechia reported since the publication of Brodo's (1991) revision are summarized, and some couplets from the key in that publication are emended with the addition of O. brodoi and O. xanthostoma. The latter is reported new to Oregon.

Although there is a distributional list of mosses in New York State (Ketchledge 1980) no one has published a statewide liverwort or hornwort list. We have included all New York specimens from herbaria both in New York State and several other states, and from the 19th century to the present. We present here a list of liverworts and hornworts by county, with current nomenclature from Söderström et al. (2016) together with synonymy and doubtful and rejected taxa. We present the number of species per county and provide a firm basis for future records. In addition, there is a short history of liverwort exploration and collection in New York State. We report 205 taxa of liverworts and 7 taxa of hornworts.
