  • Monitoring Air Quality in Class I Wilderness Areas of the Northeastern United States Using Lichens and Bryophytes Alison C
    United States Department of Agriculture Monitoring Air Quality in Class I Wilderness Areas of the Northeastern United States Using Lichens and Bryophytes Alison C. Dibble, James W. Hinds, Ralph Perron, Natalie Cleavitt, Richard L. Poirot, and Linda H. Pardo Forest Service Northern Research Station General Technical Report NRS-165 December 2016 1 Abstract To address a need for air quality and lichen monitoring information for the Northeast, we compared bulk chemistry data from 2011-2013 to baseline surveys from 1988 and 1993 in three Class I Wilderness areas of New Hampshire and Vermont. Plots were within the White Mountain National Forest (Presidential Range—Dry River Wilderness and Great Gulf Wilderness, New Hampshire) and the Green Mountain National Forest (Lye Brook Wilderness, Vermont). We sampled epiphyte communities and found 58 macrolichen species and 55 bryophyte species. We also analyzed bulk samples for total N, total S, and 27 additional elements. We detected a decrease in Pb at the level of the National Forest and in a subset of plots. Low lichen richness and poor thallus condition at Lye Brook corresponded to higher N and S levels at these sites. Lichen thallus condition was best where lichen species richness was also high. Highest Hg content, from a limited subset, was on the east slope of Mt. Washington near the head of Great Gulf. Most dominant lichens in good condition were associated with conifer boles or acidic substrates. The status regarding N and S tolerance for many lichens in the northeastern United States is not clear, so the influence of N pollution on community data cannot be fully assessed.

  • Lichens and Allied Fungi of the Indiana Forest Alliance
    2017. Proceedings of the Indiana Academy of Science 126(2):129–152 LICHENS AND ALLIED FUNGI OF THE INDIANA FOREST ALLIANCE ECOBLITZ AREA, BROWN AND MONROE COUNTIES, INDIANA INCORPORATED INTO A REVISED CHECKLIST FOR THE STATE OF INDIANA James C. Lendemer: Institute of Systematic Botany, The New York Botanical Garden, Bronx, NY 10458-5126 USA ABSTRACT. Based upon voucher collections, 108 lichen species are reported from the Indiana Forest Alliance Ecoblitz area, a 900 acre unit in Morgan-Monroe and Yellowwood State Forests, Brown and Monroe Counties, Indiana. The lichen biota of the study area was characterized as: i) dominated by species with green coccoid photobionts (80% of taxa); ii) comprised of 49% species that reproduce primarily with lichenized diaspores vs. 44% that reproduce primarily through sexual ascospores; iii) comprised of 65% crustose taxa, 29% foliose taxa, and 6% fruticose taxa; iv) one wherein many species are rare (e.g., 55% of species were collected fewer than three times) and fruticose lichens other than Cladonia were entirely absent; and v) one wherein cyanolichens were poorly represented, comprising only three species. Taxonomic diversity ranged from 21 to 56 species per site, with the lowest diversity sites concentrated in riparian corridors and the highest diversity sites on ridges. Low Gap Nature Preserve, located within the study area, was found to have comparable species richness to areas outside the nature preserve, although many species rare in the study area were found only outside preserve boundaries. Sets of rare species are delimited and discussed, as are observations as to the overall low abundance of lichens on corticolous substrates and the presence of many unhealthy foliose lichens on mature tree boles.

LENDEMER & RICHARD C. HARRIS ABSTRACT. – Geographically disjunct and ecologically unusual populations of Cladonia apodocarpa from hardwood swamps are reported from southeastern North Carolina, and assignment to that species is confirmed with analyses of nrITS sequence data. The separation of Lecanora cinereofusca var. cinereofusca and L. cinereofusca var. appalachensis is discussed in the light of analyses of mtSSU and nrITS sequence data. Lecanora cinereofusca var. appalachensis is considered to merit recognition at the species level, for which the name L. saxigena Lendemer & R.C. Harris (nomen novum pro L. appalachensis (Brodo) non L. appalachensis Lendemer & R.C. Harris) is introduced. Phlyctis ludoviciensis is formally placed in synonymy with P. boliviensis. Phlyctis willeyi is shown to belong to the genus Leucodecton and the new combination L. willeyi (Tuck.) R.C. Harris is proposed. Piccolia nannaria is hypothesized to be a parasite on Pyrrhospora varians and is shown to be more widespread in the Coastal Plain than previously thought. Schismatomma rappii is revised, illustrated, and shown to be widespread in the Coastal Plain of southeastern North America. Tylophoron hibernicum is confirmed to be the correct name for all North American records of T. protrudens. KEYWORDS. – Sandhills, maritime forest, barrier island, Mid-Atlantic, taxonomy, floristics.

  • Parmelioid Lichen Biodiversity and Distributional Ecology in Taiwan
    Fung. Sci. 16(3, 4), 39–46, 2001 Parmelioid lichen biodiversity and distributional ecology in Taiwan Ming-Jou Lai P. O. Box 834, Tunghai University, Taichung, Taiwan 407 (Accepted August 14, 2001) ABSTRACT In total, 19 genera and 97 species are so far known to represent the Taiwanese Parmelia and related genera. In the present study, the correlation of temperature-related habitat preference with the maximum floristic di- versity of parmelioid lichens is analyzed. The coefficient of community (C.C.) is used to compare the floris- tic similarity of parmelioid lichens between the different elevational forest vegetation zones. The boreal or northern temperate elements such as Parmelia, Punctelia, Melanelia, Parmeliopsis, and Imshaugia are common in Tsuga-Picea or Abies forests at higher elevations; whereas Parmotrema, Bulbothrix, Hy- potrachyna, Myelochroa, Parmelinella, Parmelinopsis, Relicina, Rimelia, Canomaculina, and Xantho- parmelia are characteristic of the meridional or pantropical elements which predominate the lowland to montane forests of Quercus, Machilus-Castanopsis, or Ficus-Machilus types. This major distributional differentiation is discussed in terms of the divergent morphogenetic lines based on the cortical struc- tures which differentiate the pseudocyphellate and the epicorticate genera and species (Hale, 1981). Genera having a pored epicortex show the highest biodiversity at submontane-montane elevations (500– 2,500 m), where the forest vegetation is dominated by Machilus-Castanopsis and Quercus (the evergreen broadleaf

Mycosphere 5(6), 770–789, Doi 10.5943/mycosphere/5/6/8 Abstract A detailed morphological and anatomical investigation of the type specimens of the current- ly accepted species of Parmelinella (Parmeliaceae, Lichenized Fungi) confirmed the current spe- cies delimitations and revealed additional characteristics. The name Parmelia mutata is removed from synonymy with Parmelinella versiformis and proposed as a new combination, and Parmelia nimandairana is removed from Parmelinella wallichiana and proposed as another new combina- tion. Parmelinella salacinifera is proposed as a new combination. A lectotype is designated for Parmelinella versiformis. A key to all currently accepted species of the genus is presented. Key words – Canoparmelia – Parmelina – Parmotremopsis – cilia – salazinic acid Introduction Elix & Hale (1987) installed the genus Parmelinella for three species previously included in Parmelina (P. wallichiana, P. manipurensis and P. simplicior) with broad, rotund lobes, an emaculate thallus, sparse, simple cilia more or less restricted to the axils, simple black rhizines, ellipsoid ascospores, short cylindrical conidia, and salazinic and consalazinic acids in the medulla. A key for the differentiation of this and some further newly proposed genera, all segregates of Parmelina, and a table containing many characteristics for them was included with the descriptions of the genera.

Endolichenic fungi (ELF) are one of the inhabitants living in lichen thalli, and have potential ecological and industrial applications due to their various secondary metabolites. As the function of endophytic fungi on the plant ecology and ecosystem sustainability, ELF may have an influence on the lichen diversity and the ecosystem, functioning similarly to the influence of endophytic fungi on plant ecology and ecosystem sustainability, which suggests the importance of understanding the diversity and community pattern of ELF. In this study, we investigated the diversity and the factors influencing the community structure of ELF in Jeju Island, South Korea by analyzing 619 fungal isolates from 79 lichen samples in Jeju Island. A total of 112 ELF species was identified and the most common species belonged to Xylariales in Sordariomycetes.

Canadian Field-Naturalist 132(4): 394–406. https:// doi.org/10.22621/cfn.v132i4.1997 Abstract Bioblitzes are typically 24-hour biological surveys of a defined region carried out by taxonomic specialists, citizen scientists, and the general public. The largest in Canada is the Ontario BioBlitz, an annual event held in the Greater Toronto Area (GTA). Between 2013 and 2016, we examined the feasibility of including lichens and allied fungi in the Ontario BioBlitz. These taxa are often overlooked, understudied, and taxonomically difficult. We completed a bioblitz in each of the four major watersheds in the GTA and recorded 138 species in 72 genera which, combined with all previous collections, totals 180 species in 88 genera in the area. Thirteen of the species we collected are provincially ranked as S1 (critically imperilled), S2 (imperilled), or S3 (vulnerable).

Macrolichen diversity was first catalogued by Moore (1968), followed by Harris (1990, 1995). “Lichens of North America” also contains photographs and descriptions of many of Florida’s macrolichens (Brodo et al. 2001). The aim of this book is to compliment these other resources and provide more field oriented keys to the macrolichen diversity. We hope to encourage the incorporation of lichens into field oriented ecological studies. Many of the species included in the keys are based lists and information from Harris (1990, 1995). In a few cases with a few rare Genera, Harris’ key very similar.
