“…Of the remaining 50 taxa not in those keys, 20 are either lichenicolous fungi, which are not covered in either the original Ottawa lichen inventory or in Brodo (2016), or are stubble lichens and fungi, the so-called calicioid species. The calicioids are almost all well covered in some recent, readily available articles (e.g., Selva and Tibell 1999;McMullin et al 2018b;Gockman et al 2020); most of the parasitic, lichenicolous fungi can be identified using the fairly comprehensive keys by Ihlen and Wedin (2008), which cover Swedish species. For these reasons, only brief notes will be included in the annotated lists, and only for the taxa not covered in the references above.…”

The inventory of lichens, allied fungi, and their parasites in the Ottawa region has grown from 391 in 1988 to 543 today, almost entirely because of the discovery of species overlooked in previous years and the inclusion of fungal parasites. In addition, almost 140 names have changed with reclassifications and re-identifications. These changes are presented here together with a list of synonyms updating the 1988 list. Vouchers are cited for all new records, and notes are presented for many species neither described nor keyed out in easily accessible literature. Reference is made to the new, complete list of lichens and lichenicolous fungi available online. The new checklist includes one species new for North America (Tremella christiansenii); five species and one variety new for Canada (Caloplaca parvula, Caloplaca reptans, Cladonia petrophila, Enchylium tenax var. ceranoides, Leprocaulon adhaerens, and Merismatium peregrinum); four new for Ontario (Caloplaca reptans, Kiliasia tristis, Lempholemma chalazanum, and Rinodina fimbriata); and nine new for Quebec (Arthonia helvola, Arthonia hypobela, Caloplaca parvula, Cladonia petrophila, Lempholemma chalazanum, Leprocaulon adhaerens, Merismatium peregrinum, Rimularia badioatra, and Tremella christiansenii). Although the climate of the region is warming, especially with higher minimum temperatures in winter, the lichen biota has not increased as a result but, in fact, may be threatened by the effects of climate change on the health of the forests and the trees that support lichens. Air quality has improved in recent decades, allowing numerous lichens to again become established in urban areas. Local areas of especially rich lichen diversity can be found on both the Ontario and Quebec sides of the region, and some of these “hot-spots” are mentioned. Other factors influencing the decrease or increase of lichen cover are also discussed.

“…In Minnesota, S. americanum can be seperated from other sterile crustose lichens by the presence of sporodochia, which produce l-septate ellipsoid conidia, and by its felty ecorticate thallus (Lendemer et al 2013).
