Species Fact Sheet SPECIES FACT SHEET Common Name: Burnet’s skin lichen Scientific Name: Leptogium burnetiae C.W. Dodge Kingdom: Fungi Division: Ascomycota Class: Lecanoromycetes Order: Peltigerales Family: Collemataceae Nomenclature The nomenclature of this species has changed several times, leading to some confusion. C. W. Dodge named L. burnetiae in 1964. Sierk (1964) named North American specimens Leptogium hirsutum. In 1973, Jørgensen combined L. hirsutum into a variety of L. burnetiae writing, "L. hirsutum is so closely related to it and best treated as a variety of it [sic]." In 1997 he included only L. burnetiae (not L. burnetiae var. hirsutum) in a key to the hairy Leptogium species of the world, evidently deciding there was no discernable difference between the variety and the species in the strict sense. Technical Description: Thallus foliose, gelatinous when wet, medium-sized, 3-10 cm diameter, loosely adnate. Lobes 3- 15 mm wide, with rounded margins. Lower surface pale to medium gray, smooth, with dense white (rarely pale brown) tomentum of long cylindrical hairs. Upper surface medium gray to bluish gray when dry, without definite wrinkles or ridges, matte to somewhat shiny, with or without small white hairs. Isidia originate as single, separate papillae on lobe surface, somewhat in from margin, then become cylindrical, simple to branched to dense and coralloid; also common in a single row along margins. Isidia matte and similar in color to thallus or slightly darker. Soredia absent. Medulla formed of densely packed hyphae, mostly lying parallel to the cortex and forming an almost solid hyphal mass in the center of the medulla. On the top and bottom of this mass, cyanobacteria are packed so tightly that their chains are not readily visible; instead they are visible as single cells (Stone 2010). Apothecia rare, laminal, stalked, 0.5-2.5 mm wide. Spores colorless, with crosswalls and longitudinal walls (muriform), 30-45 x 12-18 µm. Photobiont cyanobacterial (Nostoc). Chemistry: Spot test reactions negative. No secondary metabolites have been detected. (Brodo et al. 2001; Nash et al. 2004). Other descriptions and illustrations: Hinds and Hinds 2007, Jørgensen 1997, Nash et al. 2004, Stone 2010. Distinctive Characters: All Leptogium species are gelatinous lichens that swell and become jelly-like when wet. They are unstratified; the photobiont does not form a distinct layer within the thallus but is intermixed with fungal hyphae. Unlike Collema species, they do have an upper and lower cellular cortex, appearing as a surface layer of square to shortly rectangular cells. These features can best be seen with a compound microscope (see below). (1) blue-gray, foliose, gelatinous lichen with a densely white-hairy lower surface, (2) isidia that originate as single bumps on the surface, become cylindrical and then branched to coralloid with age, (3) medulla with tightly packed hyphae mostly parallel to and some perpendicular to the cortices. Similar Species Leptogium saturninum is most similar to L. burnetiae and can be very difficult to distinguish. In L. saturninum, surface coloration and texture appear to be connected. Isidia begin as a pattern of dark coloration near the edge of a lobe. The pattern originates as an even speckling of dark spots on the surface. As the thallus grows and widens this even dusting of dark particles becomes divided into patches, leaving bare, light-colored tracks through somewhat angular patches of dark-colored fine particles. With age, these dark areas begin to become rough and isidia erupt out of the thallus surface, destroying the cortex and forming patches of granular isidia which then become dense dark piles of granular isidia. (Stone 2010). In L. burnetiae, isidia originate as single, separate papillae on lobe surface, somewhat in from margin, then become cylindrical, simple to branched to dense and coralloid; also common in a single row along margins. Isidia similar in color to thallus or slightly darker. The structure of the medulla, seen in cross section, is also a distinguishing character. To clearly see the difference in medulla type, extremely thin sections are essential. If the sections are too thick, multiple layers of hyphae obscure the medullar structure. In L. saturninum, the medulla is formed of hyphae Perpendicular to and parallel to the upper and lower cortices, separated by spaces so the whole medulla looks airy and open. Within this open framework, chains of cyanobacteria lie in curves. Thalli of L. saturninum are variable in thickness from 100 to 300 µm, but the same structure is found in all. The amount of space between hyphae does vary from nearly touching to quite widely spaced, but the typical medulla is quite open-looking. In contrast, the medulla of L. burnetiae is formed of densely packed hyphae, mostly lying parallel to the cortex and forming an almost solid mass of fungal strands in the center of the medulla. Above and below this mass, cyanobacteria are packed so tightly that their chains are not readily visible; instead they are visible as single cells. Thalli of L. burnetiae seem quite variable in overall thickness and thickness of the central hyphal strand mass, but the pattern of a dense central-medullar mass with dense algae above and below remains consistent. Leptogium pseudofurfuraceum has a white-tomentose lower surface and cylindrical isidia. However, unlike L. burnetiae, it has a finely wrinkled upper surface, and a reddish-brown to brown-gray color. The dark brown to black, shiny isidia have a distinct dimple at the tip. Collema species are also dark-colored gelatinous lichens, but they lack an upper and lower cortex. This can be observed with a wet mount of a cross-section of the thallus through a compound microscope; see illustrations on page 15 in Brodo et al. (2001). In addition, Collema species are rarely hairy. Leptochidium albociliatum may have a white-hairy lower surface, but can be distinguished by short, stiff, clear, marginal hairs that are usually abundant and conspicuous with a hand lens. Fact Sheet for Leptogium burnetiae 2 Life History: L. burnetiae is often sterile, producing apothecia only occasionally. However, it reproduces asexually through abundant isidia, which are usually present year-round. Isidia are heavy propagules, therefore dispersal is limited. Range, Distribution, and Abundance: Globally, this species is widespread in the montane tropics, extending into warm temperate regions of Asia, Africa, Europe and North America (Nash et al. 2004). In the Pacific Northwest, it occurs in Washington, British Columbia and Alaska. It has been verified from only one location in Washington: in the Columbia River Gorge National Scenic Area (Björk 10428). Two specimens similar to L. burnetiae but with different structure of the medulla have been found in Oregon. One is at Saddle Mountain State Park (Derr 883) and the other in Jackson County on Crowfoot Creek (Medford District BLM, Callagan 1054). Habitat: This species is found on tree bark and on mossy rocks. In the Columbia River Gorge it occurs on Quercus garryana bark in a ponderosa pine/ garry oak/ arrowleaf balsamroot plant association at low elevations (100 and 400 feet). In Alaska, it is known from the Tongass National Forest at low-elevation sites (≤ 250 feet), where it occurs on Alnus sinuata, Picea sitchensis, Salix sp., and Populus trichocarpa (U.S. Department of Agriculture (no date). Threats: For this cyanolichen, shade and air moisture are an important part of the habitat, so any change in forest density or shading could degrade the habitat. The primary threat to this species is forest management activities that remove host trees or change the moisture regime. Timber harvest projects that remove or damage oaks, cottonwoods, and other hardwoods, especially in riparian areas, may directly threaten populations or reduce habitat (D. Stone, personal observation). Conservation considerations: Protect the known site and the two possible sites. Known populations can be protected by restricting removal of host trees and nearby habitat, preserving the light and moisture regime. Search riparian areas on Federal lands for more populations. Continue to protect riparian corridors, with large enough buffers to maintain humidity regimes. Conservation rankings: Global: G3G5. National: not ranked. ORBIC: S1. WNHP: not ranked.

In lichens, these phases comprise dispersal, establishment, and growth. This thesis aimed at increasing the knowledge on epiphytic cyanolichens by studying different aspects linked to these life stages, including species colonization extinction dynamics, survival and vitality of lichen transplants, and the genetic symbiont diversity in the genus Nephroma. Paper I reveals that local colonizations, stochastic, and deterministic extinctions occur in several epiphytic macrolichens. Species habitat-tracking metapopulation dynamics could partly be explained by habitat quality and size, spatial connectivity, and possibly facilitation by photobiont sharing. Simulations of species future persistence suggest stand-level extinction risk for some infrequent sexually dispersed species, especially when assuming low tree numbers and observed tree fall rates. Forestry practices influence the natural occurrence of species, and retention of trees at logging is one measure to maintain biodiversity. However, their long-term benefit for biodiversity is still discussed.

  • 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.

    The Lichenologist 46(5): 627–656 (2014) 6 British Lichen Society, 2014 doi:10.1017/S002428291400019X Extended phylogeny and a revised generic classification of the Pannariaceae (Peltigerales, Ascomycota) Stefan EKMAN, Mats WEDIN, Louise LINDBLOM and Per M. JØRGENSEN Abstract: We estimated phylogeny in the lichen-forming ascomycete family Pannariaceae. We specif- ically modelled spatial (across-site) heterogeneity in nucleotide frequencies, as models not incorpo- rating this heterogeneity were found to be inadequate for our data. Model adequacy was measured here as the ability of the model to reconstruct nucleotide diversity per site in the original sequence data. A potential non-orthologue in the internal transcribed spacer region (ITS) of Degelia plumbea was observed. We propose a revised generic classification for the Pannariaceae, accepting 30 genera, based on our phylogeny, previously published phylogenies, as well as available morphological and chemical data. Four genera are established as new: Austroparmeliella (for the ‘Parmeliella’ lacerata group), Nebularia (for the ‘Parmeliella’ incrassata group), Nevesia (for ‘Fuscopannaria’ sampaiana), and Pectenia (for the ‘Degelia’ plumbea group). Two genera are reduced to synonymy, Moelleropsis (included in Fuscopannaria) and Santessoniella (non-monophyletic; type included in Psoroma). Lepido- collema, described as monotypic, is expanded to include 23 species, most of which have been treated in the ‘Parmeliella’ mariana group. Homothecium and Leightoniella, previously treated in the Collemataceae, are here referred to the Pannariaceae. We propose 41 new species-level combinations in the newly described and re-circumscribed genera mentioned above, as well as in Leciophysma and Psoroma. Key words: Collemataceae, lichen taxonomy, model adequacy, model selection Accepted for publication 13 March 2014 Introduction which include c.

  • Leptogium Teretiusculum Species Fact Sheet
    SPECIES FACT SHEET Common Name: shrubby vinyl Scientific Name: Leptogium teretiusculum (Wallr.) Arnold Division: Ascomycota Class: Ascomycetes Order: Lecanorales Family: Collemataceae Technical Description: Thallus gelatinous, tiny, forming minute brownish to brownish-grey cushions or tufts 0.5mm to 2 cm wide, composed of many small brown, cylindrical, knobby isidia that become very branched (coralloid), either attached directly to the substrate or attached to very small foliose lobes that are obscured by the isidia and difficult to see. Medulla of isodiametric fungal cells resembling parenchyma (requires a very thin cross-section examined under a compound scope), cells to 2:1. Photosynthetic partner (photosymbiont) the cyanobacterium Nostoc. Isidia constricted at places along their length, giving a segmented, knobby look, 0.03-0.1 mm in diameter. European specimens of L. teretiusculum have an overall gray color with some browning at the tips, with thin knobby isidia that become wider and flatter as they mature, resembling a tiny Opuntia cactus, the isidia eventually becoming small foliose lobes with new isidia attached. Some European specimens are flattened, lying parallel to the substrate Chemistry: all spot tests negative. Distinctive Characters: Tiny thalli composed of cylindrical, knobby isidia, the medulla parenchyma-like. Similar species: Leptogium cellulosum looks very similar but has cylindrical isidia with dimpled tips. Martin et al. (2002) discuss at length the morphological distinctions between L. teretiusculum and L. cellulosum. Stone and Ruchty (2006) also discuss the distinctions and show photographs. Other descriptions and illustrations: Stone & Ruchty (2006); Sierk (1964); McCune & Geiser (2009): 183; Goward et al. (1994): p. 68; Purvis et al. (1992): p.356.

  • Revisions of British and Irish Lichens
    Revisions of British and Irish Lichens Volume 2 September 2020 Peltigerales: Collemataceae Cover image: Scytinium turgidum, on a limestone grave monument, Abney Park cemetery, Stoke Newington, Middlesex, England. Revisions of British and Irish Lichens is a free-to-access serial publication under the auspices of the British Lichen Society, that charts changes in our understanding of the lichens and lichenicolous fungi of Great Britain and Ireland. Each volume will be devoted to a particular family (or group of families), and will include descriptions, keys, habitat and distribution data for all the species included. The maps are based on information from the BLS Lichen Database, that also includes data from the historical Mapping Scheme and the Lichen Ireland database. The choice of subject for each volume will depend on the extent of changes in classification for the families concerned, and the number of newly recognized species since previous treatments. To date, accounts of lichens from our region have been published in book form. However, the time taken to compile new printed editions of the entire lichen biota of Britain and Ireland is extensive, and many parts are out-of-date even as they are published. Issuing updates as a serial electronic publication means that important changes in understanding of our lichens can be made available with a shorter delay. The accounts may also be compiled at intervals into complete printed accounts, as new editions of the Lichens of Great Britain and Ireland. Editorial Board Dr P.F.
