KLOPMEYER B.S. in Botany and Zoology, Eastern Illinois University, 1979 ABSTRACT OF A THESIS Submitted in partial fulfillment of the requirements for the degree of Master of Science at the Graduate School of Eastern Illinois University CHARLESTON , ILLINOIS 1981 40386? This study represents a taxonomic survey of the hepati­ cae of east-central Illinois . The counties included in this study were Coles and Clark, located in the eas t- central por­ tion af the state , near the Indiana stateline . Of the areas included in this study, two are in Clark county, Rocky Branch and Rocky Hollow, and one in Coles county, Rock's Park . The influence of the Wisconsin glacier, and its ter­ minal moraine located in southern Coles county, greatly in­ fluenced the topography and ultimately the specific habitats for the hepaticae . The majority of the liverworts encoun­ tered in these counties are found in the numerous sandstone outcrops along rivers and streams . These outcrops were ex­ posed due to the cutting action of the glacial melt water . A key was composed from the combination of the keys present in current literature . Illustrations and descrip­ tions are provided for each of the genera and species lo­ cated in these two counties . In some instances , specific locations within these counties are included for any of the species considered rare or endangered . A total of forty-seven liverworts have been collected in these counties. Four are considered to be rare or en­ dangered . They are Ptilidium pul cherrimum (G .Web.) Hampe , Blepharostoma trichophyl lum (L.) Dum., Trichocolea tomen- tella (Ehrh .) Durn. , and Marchantia po lymo rph a L. The sur­ vival of these , and liverworts in general , as well as other rare plants , is dependent upon the preservation of these areas .

J6 v 1 INTRODUCTION The purpose of this paper is to present a reasonably simplified key to the Hepaticae of east-centra� Illinois. The liverworts are usually an overlooked entity of the plant kingdom due to their small size, lack of common names, dif­ ficulty in determining their correct identification, and absence of any economic importance . Therefore , the keys in th is paper have been greatly simplified by the elimina­ tion of many technical terms and descriptions to help alle­ viate the problems of confusion and frustration encountered in most keys . The illus trations are of the basic morpho­ logical characteristics of each of the species , sufficient enough to separate them from each other . These illustrations were mainly reproduced from Schuster (1953, 1966) and Steere (1964) by use of an Arto-Graph drawing machine . The keys , with the exception of the key to the genus Frullania, which is based on Evans (1897) , are derived from the combined sources of the keys present in current literature� The combination was prepared in order to simplify the keying by differentiating the morphological characteristics of the plants through the use of a hand lens or a dissecting stereo microscope . The nomenclature is based on the current class­ ification by Stotlar (1977) . Some liverworts , which have 2 been included in this paper, are extremely rare or, are apparently thought to be absent in east-central Illinois . These liverworts are fairly common in the Smoky Mountains and the northern regions of the United States . Therefore, this key can be utilized for plants collected in those areas . It is hoped that th is paper can be used by beginning bry­ ologists to aid them in identifying the liverworts to their respe ctive genera, then consulting more complete references for specific identification . 3 DESCRIPTION OF THE STUD Y AREAS This study was conducted in Coles and Clark counties , in east- central Illinois (Fig. 1) . These counties are bor­ dered to the north by Douglas and Edgar counties ; west by Moultrie and Cumberland counties ; south by Crawford county; and , east

  • Liverworts of the Wellington Area J
    Liverworts of the Wellington Area J. E. Braggins1 LIVERWORT FEATURES Liverworts are plants similar in many ways to mosses: they are usually small, and generally lack the hard supporting tissues of larger plants such as ferns. Like ferns, liverworts show alternation of generations, having separate gametophyte and sporophyte entities; unlike ferns the sporophyte is not a separate plant. As with mosses, the gametophyte generation is the dominant phase of the life cy- cle, and the sporophyte generation is permanently dependent on it. Liverworts show a greater range in general morphology and form than mosses, and as well as normal leafy plants, there are dozens of species of thalloid liverworts that lack organisation into stems and leaves. The most striking differences between mosses and liverworts are in the sporophytes where liverworts have a simple outer wall lacking the peristome of mosses, and in the capsule which usually splits into four valves to release the spores. Mixed amongst the spores are hair- like elaters, which flick and twist as they dry out, helping to throw the spores clear. The stalk that bears the capsule (the seta) remains short until the capsule is mature, then, by cell elongation, it expands rapidly to its full size. Thus, the expanded seta of a liverwort is a delicate translucent structure, not tough and wiry like a moss seta which elongates slowly by cell growth. The vegetative parts of leafy liverworts differ from mosses in details of cell shape, contents, leaf structure (liverwort leaves lack a central nerve or vein), shape (liverwort leaves are rarely markedly elongate but are often complexly lobed) and position.

    Opuscula Philolichenum, 11: 141–144. 2012. *pdf effectively published online 21September2012 via (http://sweetgum.nybg.org/philolichenum/) Puttea (Pilocarpaceae) in eastern North America 1 2 WILLIAM R. BUCK AND JAMES C. LENDEMER ABSTRACT. – Puttea margaritella is reported new to eastern North America from a single collection from the Gaspé Peninsula of Québec, Canada and P. exsequens is reported as new to North America from a single collection from New Brunswick, Canada. INTRODUCTION Puttea S. Stenroos & Huhtinen was described a few years ago (Stenroos et al. 2009) to accommodate a single species of hepaticolous lichen, Lecidea margaritella Hulting. The marginally lichenized fungus was reported to be restricted to growing on the hepatic Ptilidium pulcherrimum (Weber) Hampe. However, when the species was reported from western North America (Spribille et al. 2010) it was reported to also grow on Ptilidium californicum (Austin) Underw. Stenroos et al. (2009) speculated that Puttea is either a necrotrophic parasite or colonizes already dead, decaying shoots of the hepatic. Indeed, the material found by us in eastern Canada is growing over the dead and decaying portions of the Ptilidium pulcherrimum, not on the living, reddish plants. The apothecia are white and one might be misled in thinking they are conspicuous, but the largest ones are only 0.4 mm in diameter and therefore the species is essentially invisible without magnification. The scanty thallus is not visible in the field (and scarcely so under the dissecting microscope). Until recently it was known only from boreal areas of Europe, specifically Fennoscandia (including adjacent Karelia) and woodland areas of central Europe.

  • Anomalies in Male Receptacles of Plagiochasma Appendiculatum Lehm
    American International Journal of Available online at http://www.iasir.net Research in Formal, Applied & Natural Sciences ISSN (Print): 2328-3777, ISSN (Online): 2328-3785, ISSN (CD-ROM): 2328-3793 AIJRFANS is a refereed, indexed, peer-reviewed, multidisciplinary and open access journal published by International Association of Scientific Innovation and Research (IASIR), USA (An Association Unifying the Sciences, Engineering, and Applied Research) Anomalies in male receptacles of Plagiochasma appendiculatum Lehm. & Lindenb Pallvi Sharma and Anima Langer Department of Botany, University of Jammu, Jammu, Jammu and Kashmir-180006, INDIA Abstract: Plagiochasma appendiculatum Lehm. & Lindenb. belongs to the family Aytoniaceae which includes five genera (Plagiochasma, Reboulia, Asterella, Mannia and Cryptomitrium). Most of these genera show abnormalities in the development of reproductive structures. In the present paper, anomalies in the morphology and anatomy of male receptacles are reported in P.appendiculatum. Keywords: Plagiochasma appendiculatum; Aytoniaceae; Anomalies; Male receptacles I. Introduction Plagiochasma appendiculatum is a thalloid hepatic which is dorso-ventrally flattened. The male receptacles are normally horse-shoe shaped, sessile and present on the dorsal surface of the thallus, while the female ones are stalked, variously lobed (usually 3-5 lobed) and present on the main thallus too. Abnormality in their behaviour has been observed by bryologists like Kashyap and Bapna [1,4]. A second forking in the two lobes of androecium of P.appendiculatum is one of the important discovery (Kashyap, 1919). Abnormal female receptacles in the same genus were studied by Bapna and Bhagat [1,2] . Anomalies in the reproductive structures have also been studied in other members of family Aytoniaceae like unusual female receptacles in Asterella blumeana nees and Asterella khasiana [5] and abnormal male receptacles in Reboulia hemispherica [6].

  • Bryoflora of the Great Cypress Swamp Conservation Area, Sussex County, Delaware and Worcester County, Maryland
    The Maryland Naturalist 43 (3-4):9-17 . July/December 1999 The Bryoflora of the Great Cypress Swamp Conservation Area, Sussex County, Delaware and Worcester County, Maryland William A. McAvoy Introduction In 1998 the Delaware Natural Heritage Program (DNHP), with funding from the U.S. Environmental Protection Agency, completed a biological/ecological survey of the Great Cypress Swamp Conservation Area (GCSCA). The GCSCA is located in the central portion of the Delmarva Peninsula (a land area composed of the coastal plain counties of Delaware and the eastern shore counties of Maryland and Virginia) and lies on the border of Sussex County, Delaware and Worcester County, Maryland (Figure 1). Though the survey included a variety of inventories (avian, amphibian and reptile, natural community, and rare vascular plants), it is the data collected on bryophytes (mosses and liverworts) that are reported here. The study ofbryophytes on the Delmarva Peninsula has attracted very little interest over the years, and a search of the literature revealed only four pertinent papers. Owens (1949), while studying at the University of Maryland, submitted a graduate thesis titled A Preliminary List of Maryland Mosses and their Distribution. This annotated list, containing county distribution data and briefhabitat notes, included 198 taxa of mosses for the state of Maryland, with 65 taxa attributed to the eastern shore counties of Delmarva. Owens's list was based solely on pre-I 949 collections at US and MARY (Herbaria acronyms follow Holmgren et al. 1990). Confirmations and determinations were made by the author, as well as by numerous other authorities in the field ofbryology (Owens 1949).

PEROLD* Keywords: Asterella, A. bachmannii, A. marginata, A. muscicola, A. wilmsii, Aytoniaceae, Hepaticae, Marchantiales, Phragmoblepharis, Reboulioideae, section Saccatae, southern Africa ABSTRACT A taxonomic account of the genus Asterella, and four local representatives, A. muscicola, A. bachmannii, A. marginata and A. wilmsii, subgenus Phragmoblepharis, is given here. A key to the species is provided. Two specimens identified by Arnell ( ll)63) as Reboulia hemisphaerica, Collins 775 and Eyles CH 1175, are actually A. wilmsii', the presence of the genus Reboulia in southern Africa is therefore not confirmed and should be deleted from the annotated checklist by Magill & Schelpe (1979) and Plants of southern Africa: names and distribution (Arnold & De Wet 1993). UITTREKSEL n Taksonomiese verslag oor die genus Asterella, en vier van die plaaslike verteenwoordigers daarvan, A. muscicola, A. bachmannii, A. marginata cn A. wilmsii, subgenus Phragmoblepharis, word hier gegee.

NADEZDA A. KONSTANTINOVA1 & ANNA A. VILNET1 1Polar-Alpine Botanical Garden–Institute RAS, 184256, Kirovsk, Russia, email: [email protected], [email protected] Abstract The new species Jungermannia calcicola Konstant. et Vilnet, is described based on a critical reinvestigation of morphologi- cal features and molecular analyses of trnL–trnF and trnG intron cpDNA sequences of forty samples of Jungermannia s. str. The new species is described and illustrated as well as noting its differentiation from allied species and distribution patterns. New data on some taxonomical ambiguities and on the taxa delimitation in the Jungermannia s. str. are discussed. Key words: Jungermannia calcicola sp. nov., liverworts, taxonomy, molecular systematics, distribution Introduction Jungermannia Linnaeus (1753: 1131) is one of the oldest described genera of leafy liverworts. Since its description the treatment of this genus has been drastically changed. At the end of the 20th to the beginning of the 21st centuries most bryologists accepted Jungermannia in the wide sense including Solenostoma Mitten (1865a: 51), Plectocolea (Mitten 1865b: 156) Mitten (1873: 405), Liochlaena Nees in Gottsche et al. (1845: 150). But in recent molecular phylogenetic studies Jungermannia s. lat. has been proved to be a mixture of phylogenetically unrelated taxa, some of which have been elevated to distinct families, e.g., Solenostomataceae Stotler et Crand.-Stotl.

  • About the Book the Format Acknowledgments
    About the Book For more than ten years I have been working on a book on bryophyte ecology and was joined by Heinjo During, who has been very helpful in critiquing multiple versions of the chapters. But as the book progressed, the field of bryophyte ecology progressed faster. No chapter ever seemed to stay finished, hence the decision to publish online. Furthermore, rather than being a textbook, it is evolving into an encyclopedia that would be at least three volumes. Having reached the age when I could retire whenever I wanted to, I no longer needed be so concerned with the publish or perish paradigm. In keeping with the sharing nature of bryologists, and the need to educate the non-bryologists about the nature and role of bryophytes in the ecosystem, it seemed my personal goals could best be accomplished by publishing online. This has several advantages for me. I can choose the format I want, I can include lots of color images, and I can post chapters or parts of chapters as I complete them and update later if I find it important. Throughout the book I have posed questions. I have even attempt to offer hypotheses for many of these. It is my hope that these questions and hypotheses will inspire students of all ages to attempt to answer these. Some are simple and could even be done by elementary school children. Others are suitable for undergraduate projects. And some will take lifelong work or a large team of researchers around the world. Have fun with them! The Format The decision to publish Bryophyte Ecology as an ebook occurred after I had a publisher, and I am sure I have not thought of all the complexities of publishing as I complete things, rather than in the order of the planned organization.

    The copyright of this thesis rests with the University of Cape Town. No quotation from it or information derived from it is to be published without full acknowledgement of the source. The thesis is to be used for private study or non-commercial research purposes only. University of Cape Town Addendum (1) Soon after submitting this thesis a more recent comprehensive classification by Crandall-Stotler et al. (2009)1 was published. This recent publication does not undermine the information presented in this thesis. The purpose of including the comprehensive classification of Crandall-Stotler and Stotler (2000) was specifically to introduce some of the issues regarding the troublesome classification of this group of plants. Crandall-Stotler and Stotler (2000), Grolle and Long (2000) for Europe and Macaronesia and Schuster (2002) for Austral Hepaticae represent three previously widely used yet differing opinions regarding Lophoziaceae classification. They thus reflect a useful account of some of the motivation for initiating this project in the first place. (2) Concurrently or soon after chapter 2 was published by de Roo et al. (2007)2 more recent relevant papers were published. These include Heinrichs et al. (2007) already referred to in chapter 4, and notably Vilnet et al. (2008)3 examining the phylogeny and systematics of the genus Lophozia s. str. The plethora of new information regarding taxa included in this thesis is encouraging and with each new publication we gain insight and a clearer understanding these fascinating little plants.
