... tristicula (Nyl.) Zahlbr. FIGURE 7F & 8A. NOTES. -Agonimia tristicula is widely distributed, occurring throughout portions of Asia, Australia, Europe, Macaronesia, North America and South America (Hafellner 2014). In North America it occurs mainly in montane areas of the west and as far east as the Great Lakes Basin (Fig. 8A). It was first reported from Canada from Osoyoos in British Columbia ( Goward et al. 1994). In Europe it is rare in lowland habitats but increases in frequency in montane and high alpine vegetation habitats where it grows among bryophytes over calcareous substrates or can be lichenicolous on cyanolichens such as Peltigera, Collema, and ...

In North America, A. citrinella ranges from Alaska and Nunavut south through the Rocky Mountains and alpine zones of Québec, as well as portions of coastal Maine, Nova Scotia and Newfoundland (Fig. 8D). Disjunct populations are known from the Great Lakes region in Michigan and Minnesota, where it is listed as Threatened (MNDNR ...

These are the first confirmed reports for the Great Lakes Basin which are disjunct from the nearest occurrences in the White Mountains of New Hampshire by nearly 1,300 kilometres (Fig. 8F). Newmaster et al. (1998) included this species on the first Ontario lichen list but no specimens were cited, there are no supporting reports in the literature, and no voucher was found at CANL. It is the only foliose-squamulose species of Baeomyces septum measuring (3-)4-6(-8) µm (McCune 2017(McCune , Šoun et al. 2011). While these are ...

... are the first published records of this species and extend its range north to the Thunder Bay District. It is a circumpolar arctic-alpine species occurring on non-calcareous rock or exsiccated wood (Hale 1986, Hinds & Hinds 2007. It is disjunct in the Lake Superior Region by several hundred kilometres from its more continuous range to the north (Fig. 18B). The species was found to be both saxicolous on boulders on steep talus slopes as well as lignicolous on driftwood in coastal areas of Lake ...

... The slow release of cold air from gaps in the talus blocks stunts woody vegetation encroachment favoring cryptogram-dominated communities which contrast the surrounding upland boreal forest. Termed glaciere talus, this habitat is rare in the Thunder Bay region and noted for concentrations of disjunct arctic-alpine plants (e.g., Brinker 2017;Given & Soper 1981) and lichens (Brinker 2020, Crowe 1994. Given the small number of known occurrences of Rhizoplaca ouimetensis and its preference for talus slopes, we suspect that the species is rare throughout its range. ...
Rhizoplaca ouimetensis is described new to science, growing on outcrops of diabase sills in the Lake Superior region of Ontario, Canada. It is the first known sorediate species of the genus, and a phylogenetic reconstruction based on the ITS and mtSSU markers place it in the R. chrysoleuca group. Morphologically, however, it resembles sorediate, yellow-green species of Lecanora with usnic acid, e.g., L. handelii and L. soralifera, but differs from those in forming larger, often pulvinate or minutely peltate areoles with a well-developed upper cortex and a medulla densely filled with calcium oxalate crystals.
... Recently, molecular methods are being used more in determining the lichen biodiversity of the Antarctic (Lee et al., 2008;Halıcı et al., 2017;2020;. It is important to determine the lichen biodiversity of Antarctica truly, as the organisms can be excellent biomonitors of climate change and Antarctica is a natural laboratory for these studies (Sancho et al., 2019). ...
... Lecanora atromarginata has a bipolar distribution and is found in portions of arctic Asia, Europe, Scandinavia, Arctic (Greenland, Svalbard, Canada) and Antarctica, where it occurs on calcareous, siliceous and other base-rich rock at high elevations (Kristinsson et al., 2010;Brinker, 2020). World-wide distribu-tion of Lecanora atromarginata is indicated by purple triangle in Figure 12. ...
... The lichens are the most dominant organisms of Antarctic terrestrial vegetation and important to understand the terrestrial biota of Antarctic which is under the effect of global warming. Although around 500 species of lichens were reported from Antarctica, the lichen biodiversity of the continent is far from being fully known; as in the last 5 years of our studies on Antarctic lichens, we and other scientists reported significant number of undescribed or unreported species (Halıcı et al., 2017;2020;Cao et al., 2018;Park et al., 2018;Halıcı & Bartak, 2019;Sancho et al., 2020). In our opinion, if more lichens are examined with molecular techniques, the lichen biota of Antarctic will be known more detailed. ...
Antarctica seems to many people to be a very remote, isolated, and mysterious place at the end of the world, and its name is hardly mentioned in normal life and conversation. However, considering that it plays a key role in the rapidly warming global climate system and its contribution to the continuing sea-level rise, its importance today is increasing day by day and it can be seen that it is of vital importance for humanity. There is increasing interest in the distribution of terrestrial organisms in Antarctica because of the potential use of biodiversity as a predictor or indicator of climate change. Lichenized fungi cover large areas of Antarctica that are not covered by ice and form precursor organisms that thrive in harsh environments. They are the largest contributors to biomass and diversity. The characteristic features of these organisms can be counted as developing certain protective mechanisms, adapting to temperature and radiation, and surviving even when the amount of water in their body is minimized. On the other hand, lichenized fungi are the most dominant components of Antarctic terrestrial vegetation, and their adaptation to extreme conditions; growth forms, reproduction, adaptation to environmental conditions can also be explained through mechanisms. Because of the lichens, dominant organisms of Antarctica, studying lichen biodiversity is very important. Although around 500 species of lichens were reported from Antarctica, the lichen biodiversity of the continent is far from being fully known; as in the last 5 years of our studies on Antarctic lichens, we and other scientists reported a significant number of undescribed or unreported species. So the lichen biodiversity of Antarctica is not fully known as there are still many undescribed or unreported species on the continent. In this paper, we deal with three lichenized fungal species: Arthonia glebosa Tuck., Lecanora atromarginata (H. Magn.) Hertel & Rambold and Lecidea tessellata Flörke which are common in James Ross Island, using nrITS, mtSSU, and RPB1 sequences. The lichen samples are studied by morphological and anatomical characters. In addition, to determine the phylogenetic positions of the species, we provide nrITS and mtSSU of these 3 species from Antarctica and additionally RPB1 sequences of Lecidea tessellata.
... Parmotrema hypotropum is found throughout the eastern United States and Canada (Lendemer and Knapp 2007, Lewis and Brinker 2017, Brinker 2020, in addition to the Baja peninsula and inland Mexico (Coutiño and Mojica 1985, Knudsen and Kocourková 2009, León-González and Pérez-Pérez 2020. Collections attributed to this species have been made in France, Italy, Spain and Morocco, but they were incorrectly identified, and are not included in recent checklists (Hawksworth, et al. 2008;P. ...
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.
Two lichenicolous fungi, Illosporium carneum and Ovicuculispora parmeliae, are reported as new to Japan. Illosporium carneum was found on Peltigera didactyla growing on rock in Nagano Prefecture, central Honshu, at an elevation of 2,300 m. Ovicuculispora parmeliae was found on Heterodermia japonica growing on rock in Saitama Prefecture, central Honshu, at an elevation of 1330 m.
