The site was divided into four ecologically different zones which included two coastal hardwood hammocks of different maturities, a disturbed exposed site once probably dominated by pines long extirpated and a fully exposed dwarf mangrove zone interspersed with other non-mangrove species. The mature coastal hammock yielded 172 species dominated by the family Graphidaceae, especially the subfamily Fissurinoideae and the tribe Thelotremateae. The most exposed mangrove site produced only 73 species dominated by the families Arthoniaceae, Physciaceae and Lecanoraceae. The park is also compared to two nearby South Florida preserves, Everglades National Park and Fakahatchee Strand Preserve State Park both of which have had recent lichen inventories. A surprisingly high number of species were found to be unique to each preserve suggesting at least some lichens have difficulty in dispersing themselves sexually or asexually over even moderate distances. Foray participants recovered 323 species including 315 lichenized and 8 lichenicolous fungi.

  • Taxonomy and New Records of Graphidaceae Lichens in Western Pangasinan, Northern Philippines
    PRIMARY RESEARCH PAPER | Philippine Journal of Systematic Biology DOI 10.26757/pjsb2019b13006 Taxonomy and new records of Graphidaceae lichens in Western Pangasinan, Northern Philippines Weenalei T. Fajardo1, 2* and Paulina A. Bawingan1 Abstract There are limited studies on the diversity of Philippine lichenized fungi. This study collected and determined corticolous Graphidaceae from 38 collection sites in 10 municipalities of western Pangasinan province. The study found 35 Graphidaceae species belonging to 11 genera. Graphis is the dominant genus with 19 species. Other species belong to the genera Allographa (3 species) Fissurina (3), Phaeographis (3), while Austrotrema, Chapsa, Diorygma, Dyplolabia, Glyphis, Ocellularia, and Thelotrema had one species each. This taxonomic survey added 14 new records of Graphidaceae to the flora of western Pangasinan. Keywords: Lichenized fungi, corticolous, crustose lichens, Ostropales Introduction described Graphidaceae in the country (Parnmen et al. 2012). Most recent surveys resulted in the characterization of six new Graphidaceae is the second largest family of lichenized species (Lumbsch et al. 2011; Tabaquero et al.2013; Rivas-Plata fungi (Ascomycota) (Rivas-Plata et al. 2012; Lücking et al. et al. 2014). In the northwestern part of Luzon in the Philippines 2017) and is the most speciose of tropical crustose lichens (Region 1), an account on the Graphidaceae lichens was (Staiger 2002; Lücking 2009). The inclusion of the initially conducted only from the Hundred Islands National Park (HINP), separate family Thelotremataceae (Mangold et al. 2008; Rivas- Alaminos City, Pangasinan (Bawingan et al. 2014). The study Plata et al. 2012) in the family Graphidaceae made the latter the reported 32 identified lichens, including 17 Graphidaceae dominant element of lichen communities with 2,161 accepted belonging to the genera Diorygma, Fissurina, Graphis, Thecaria species belonging to 79 genera (Lücking et al.

MycoKeys 34: 25–34. https://doi.org/10.3897/mycokeys.34.23836 Abstract Architrypethelium murisporum Luangsuphabool, Lumbsch & Sangvichien is described for a crustose lichen occurring in dry evergreen forest in Thailand. It is characterised by a green to yellow-green corticated thal- lus, perithecia fused in black pseudostromata with white rim surrounding the ostiole and small, hyaline and muriform ascospores. Currently, all species in the genus Architrypethelium have transversely septate ascospores, hence the discovery of this new species indicates that ascospore septation is variable within the genus, similar to numerous other groups of lichen-forming ascomycetes. Phylogenetic analyses of two loci (mtSSU and nuLSU) supported the position of the new species within Architrypethelium.

Mycosphere 6(3), 290–326, Doi 10.5943/mycosphere/6/3/7 Abstract The Dothideomycetes include several genera whose ascomata can be considered as apothecia and thus would be grouped as discomycetes. Most genera are grouped in the family Patellariaceae, but also Agrynnaceae and other families. The Hysteriales include genera having hysterioid ascomata and can be confused with species in Patellariaceae with discoid apothecia if the opening is wide enough. In this study, genera of the family Patellariaceae were re-examined and characterized based on morphological examination. As a result of this study the genera Baggea, Endotryblidium, Holmiella, Hysteropatella, Lecanidiella, Lirellodisca, Murangium, Patellaria, Poetschia, Rhizodiscina, Schrakia, Stratisporella and Tryblidaria are retained in the family Patellariaceae. The genera Banhegyia, Pseudoparodia and Rhytidhysteron are excluded because of differing morphology and/or molecular data.

Introduction Only a very few literature reports of lichens from Guatemala exist. Two publications, dealing explicitly with foliicolous lichens of Guatemala, are known (BARILLAS & LÜCKING 1992) and BARILLAS et al. (1993). A compilation of mainly these literature records is presented on Internet (FEUERER 2005). It is evident that the flora of lichens and lichenicolous fungi of this country is very poorly known. As far as we know, no papers dealing exclusively with lichenicolous fungi from Guatemala have ever been published.

SIPMAN Free University of Berlin Botanical Garden and Museum Königin-Luise-Str. 6-8 D-14195 Berlin, Germany Abstract A total of 296 species of lichenized fungi are reported from Singapore and presented in an annotated list with local distributional information. It is based on herbarium and literature study and the fieldwork done in the year 2000. Unidentified samples suggest the figure to be an underestimation, while some of the listed species may have become extinct. Lists of synonyms and collectors are added. Introduction Tropical conurbations, the world’s most fast-growing habitat, have turned out to harbour significant numbers of lichenized fungi.A ptroot and Seaward (1999) and Aptroot and Sipman (2001) report no less than 308 species for the city of Hongkong. Singapore seems particularly suitable for a study of lichens in an urbanized tropical area because it has received regular attention from botanists during its development from primary lowland forest with small settlements ca 1800 to extensive plantations a century later and to the present urbanized area with large built-up high rise areas interspersed by parks and secondary forest. During 1800-1964 scattered lichen collections were made by visiting and resident general botanists, e.g., E. Almquist, O. Beccari, T.R. Chipp, Kiah, A.M. Lemaitre, A.C. Maingay, H. Möller. Their collections have been investigated and published by, e.g., Krempelhuber (1875, 1877), Nylander and Crombie (1884) and Müller Argoviensis (1893).

ADVAITA, CALEB A. MORSE1,2 AND DOUGLAS LADD3 ABSTRACT. – A total of 154 lichens, four lichenicolous fungi, and one allied fungus were collected by the authors from 2004 to 2015 from Pipestone National Monument (PNM), in Pipestone County, on the Prairie Coteau of southwestern Minnesota. Twelve additional species collected by previous researchers, but not found by the authors, bring the total number of taxa known for PNM to 171. This represents a substantial increase over previous reports for PNM, likely due to increased intensity of field work, and also to the marked expansion of corticolous and anthropogenic substrates since the site was first surveyed in 1899. Reexamination of 116 vouchers deposited in MIN and the PNM herbarium led to the exclusion of 48 species previously reported from the site. Crustose lichens are the most common growth form, comprising 65% of the lichen diversity. Sioux Quartzite provided substrate for 43% of the lichen taxa collected. Saxicolous lichen communities were characterized by sampling four transects on cliff faces and low outcrops. An annotated checklist of the lichens of the site is provided, as well as a list of excluded taxa. We report 24 species (including 22 lichens and two lichenicolous fungi) new for Minnesota: Acarospora boulderensis, A. contigua, A. erythrophora, A. strigata, Agonimia opuntiella, Arthonia clemens, A. muscigena, Aspicilia americana, Bacidina delicata, Buellia tyrolensis, Caloplaca flavocitrina, C. lobulata, C.

  • Foliicolous Lichens and Their Lichenicolous Fungi Collected During the Smithsonian International Cryptogamic Expedition to Guyana 1996
    45 Tropical Bryology 15: 45-76, 1998 Foliicolous lichens and their lichenicolous fungi collected during the Smithsonian International Cryptogamic Expedition to Guyana 1996 Robert Lücking Lehrstuhl für Pflanzensystematik, Universität Bayreuth, D-95447 Bayreuth, Germany Abstract: A total of 233 foliicolous lichen species and 18 lichenicolous fungi are reported from Guyana as a result of the Smithsonian „International Cryptogamic Expedition to Guyana“ 1996. Three lichens and two lichenicolous fungi are new to science: Arthonia grubei sp.n., Badimia subelegans sp.n., Calopadia pauciseptata sp.n., Opegrapha matzeri sp.n. (lichenicolous on Amazonomyces sprucei), and Pyrenidium santessonii sp.n. (lichenicolous on Bacidia psychotriae). The new combination Strigula janeirensis (Bas.: Phylloporina janeirensis; syn.: Raciborskiella janeirensis) is proposed. Apart from Amazonomyces sprucei and Bacidia psychotriae, Arthonia lecythidicola (with the lichenicolous A. pseudopegraphina) and Byssolecania deplanata (with the lichenicolous Opegrapha cf. kalbii) are reported as new hosts for lichenicolous fungi. Arthonia pseudopegraphina growing on A. lecythidicola is the first known case of adelphoparasitism at generic level in foliicolous Arthonia. Arthonia flavoverrucosa, Badimia polillensis, and Byssoloma vezdanum are new records for the Neotropics, and 115 species are new for Guyana, resulting in a total of c. 280 genuine foliicolous species reported for that country, while Porina applanata and P. verruculosa are excluded from its flora. The foliicolous lichen flora of Guyana is representative for the Guianas (Guyana, Suriname, French Guiana) and has great affinities with the Amazon region, while the degree of endemism is low. A characteristic species for this area is Amazonomyces sprucei. Species composition is typical of Neotropical lowland to submontane humid forests, with a dominance of the genera Porina, Strigula, and Mazosia.

[Cite as: Logesh AR, Joshi S, Ingle KK & Upreti DK (2014) Some new additions to the lichen family Rocellaceae (Arthoniales) from India. Tropical Plant Research 1(1): 1–3] INTRODUCTION The genus Bactrospora A. Massal. was revised by Egea & Torrente (1993) and represented by 20 species and one variety, among them four were previously reported from India Bactrospora jenikii (Vìzda) Egea & Torrente, B. lamprospora (Nyl.) Lendemer, B. metabola (Nyl.) Egea & Torrente, B. myriadea (Fée) Egea & Torrente (Singh & Sinha 2010). The genus Bactrospora differs from similar genera Lecanactis and Opegrapha by lecideine ascomata, dark proper exciple and elongate, transversely septate, fragmenting ascospores (Ponzetti & McCune 2006). The allopatric genus Sigridea was monographed by Tehler (1993) with four species world- wide. In India Nylander (1867) recorded single species of Sigridea as Platygrapha galucomoides Nyl. which is now known as Sigridea glaucomoides (Nyl.) Tehler. Sigridea species are recognized by white thallus, circular ascomata, well developed thalline margin, hyaline, 3-septate, curved ascospores with one end tapering and the presence of psoromic acid.

The system put forth here is intended both (1) to provide a skeletal outline of the lichens and allied fungi that can be used as a provisional filing and databasing scheme by lichen herbarium/data managers and (2) to announce the online presence of an official taxonomy that will define the scope of the newly formed International Committee for the Nomenclature of Lichens and Allied Fungi (ICNLAF). The online version of the taxonomy presented here will continue to evolve along with our understanding of the organisms. Additionally, the subfamily Fissurinoideae Rivas Plata, Lücking and Lumbsch is elevated to the rank of family as Fissurinaceae. KEYWORDS. – higher-level taxonomy, lichen-forming fungi, lichenized fungi, phylogeny INTRODUCTION Traditionally, lichen herbaria have been arranged alphabetically, a scheme that stands in stark contrast to the phylogenetic scheme used by nearly all vascular plant herbaria. The justification typically given for this practice is that lichen taxonomy is too unstable to establish a reasonable system of classification. However, recent leaps forward in our understanding of the higher-level classification of fungi, driven primarily by the NSF-funded Assembling the Fungal Tree of Life (AFToL) project (Lutzoni et al. 2004), have caused the taxonomy of lichen-forming and allied fungi to increase significantly in stability. This is especially true within the class Lecanoromycetes, the main group of lichen-forming fungi (Miadlikowska et al.
