Systematic Botany 29(1):29-41. 2004 doi: http://dx.doi.org/10.1600/036364404772973960 Phylogenetic Relationships of Haplolepideous Mosses (Dicranidae) Inferred from rps4 Gene Sequences Terry A. Heddersonad, Donald J. Murrayb, Cymon J. Coxc, and Tracey L. Nowella aBolus Herbarium, Department of Botany, University of Cape Town, Private Bag, Rondebosch 7701, Republic of South Africa bThe Birmingham Botanical Garden, Westbourne Road, Edgbaston, Birmingham, B15 3TR U. K. cDepartment of Biology, Duke University, Durham, North Carolina 27708 dAuthor for Correspondence ( [email protected]) Abstract The haplolepideous mosses (Dicranidae) constitute a large group of ecologically and morphologically diverse species recognised primarily by having peristome teeth with a single row of cells on the dorsal surface. The reduction of sporophytes in numerous moss lineages renders circumscription of the Dicranidae problematic. Delimitation of genera and higher taxa within it has also been difficult. We analyse chloroplast-encoded rps4 gene sequences for 129 mosses, including representatives of nearly all the haplolepideous families and subfamilies, using parsimony, likelihood and Bayesian criteria. The data set includes 59 new sequences generated for this study. With the exception of Bryobartramia, which falls within the Encalyptaceae, the Dicranidae are resolved in all analyses as a monophyletic group including the extremely reduced Archidiales and Ephemeraceae. The monotypic Catoscopium, usually assigned to the Bryidae is consistently resolved as sister to Dicranidae, and this lineage has a high posterior probability under the Bayesian criterion. Within the Dicranidae, a core clade is resolved that comprises most of the species sampled, and all analyses identify a proto-haplolepideous grade of taxa previously placed in various haplolepideous families. -

The twenty first century has witnessed the increasing use of molecular data complemented by cytological studies in understanding the nature of bryophyte-fungal associations and unravelling the early evolution of fungal symbioses at the foot of the land plant tree. Isolation and resynthesis experiments have shed considerable light on host ranges and very recently have produced an incisive insight into functional relationships. Fungi with distinctive cytology embracing short-lived intracellular fungal lumps, intercellular hyphae and thick-walled spores in Treubia and Haplomitrium are currently being identified as belonging to a more ancient group of fungi than the glomeromycetes, previously assumed to be the most primitive fungi forming symbioses with land plants. Glomeromycetes, like those in lower tracheophytes, are widespread in complex and simple thalloid liverworts. Limited molecular identification of these as belonging to the derived clade Glomus Group A has led to the suggestion of host swapping from tracheophytes. -
Monoicous Species Pairs in the Mniaceae (Bryophyta); Morphology, Sexual Condition and Distiribution
ISSN 2336-3193 Acta Mus. Siles. Sci. Natur., 68: 67-81, 2019 DOI: 10.2478/cszma-2019-0008 Published: online 1 July 2019, print July 2019 On the hypothesis of dioicous − monoicous species pairs in the Mniaceae (Bryophyta); morphology, sexual condition and distiribution Timo Koponen On the hypothesis of dioicous − monoicous species pairs in the Mniaceae (Bryophyta); morphology, sexual condition and distiribution. – Acta Mus. Siles. Sci. Natur., 68: 67-81, 2019. Abstract: Some early observations seemed to show that, in the Mniaceae, the doubling of the chromo- some set affects a change from dioicous to monoicous condition, larger size of the gametophyte including larger leaf cell size, and to a wider range of the monoicous counterpart. The Mniaceae taxa are divided into four groups based on their sexual condition and morphology. 1. Dioicous – monoicous counterparts which can be distinguished by morphological characters, 2. Dioicous – monoicous taxa which have no morphological, deviating characters, 3. Monoicous species mostly with diploid chromosome number for which no dioicous counterpart is known, and 4. The taxa in Mniaceae with only dioicous plants. Most of the monoicous species of the Mniaceae have wide ranges, but a few of them are endemics in geographically isolated areas. The dioicous species have either a wide holarctic range or a limited range in the forested areas of temperate and meridional North America, Europe and SE Asia, or in subtropical Asia. Some of the monoicous species are evidently autodiploids and a few of them are allopolyploids from cross-sections of two species. Quite recently, several new possible dioicous – monoicous relationships have been discovered. -
Globally Widespread Bryophytes, but Rare in Europe
Portugaliae Acta Biol. 20: 11-24. Lisboa, 2002 GLOBALLY WIDESPREAD BRYOPHYTES, BUT RARE IN EUROPE Tomas Hallingbäck Swedish Threatened Species Unit, P.O. Box 7007, SE-75007 Uppsala, Sweden. [email protected] Hallingbäck, T. (2002). Globally widespread bryophytes, but rare in Europe. Portugaliae Acta Biol. 20: 11-24. The need to save not only globally threatened species, but also regionally rare and declining species in Europe is discussed. One rationale of red-listing species regionally is to be preventive and to counteract the local species extinction process. There is also a value in conserving populations at the edge of their geographical range and this is discussed in terms of genetic variation. Another reason is the political willingness of acting locally rather than globally. Among the rare and non-endemic species in Europe, some are rare and threatened both in Europe and elsewhere, others are more common outside Europe and a third group is locally common within Europe but rare in the major part. How much conservation effort should be put on these three European non-endemic species groups is briefly discussed, as well as why bryophytes are threatened. A discussion is given, for example, of how a smaller total distribution range, decreasing density of localities, smaller sites, less substrate and lower habitat quality affect the survival of sensitive species. This is also compared with species that have either high or low dispersal capacity or different longevity of either vegetative parts or spores. Examples from Sweden are given. Key words: Bryophytes, rarity, Europe, dispersal capacity, Sweden. Hallingbäck, T. (2002). -

Anomobryum Julaceum A
Bryales Anomobryum julaceum A. filiforme Slender Silver-moss 4 mm var. julaceum. var. concinnatum var. julaceum 2 mm var. julaceum 3 mm var. concinnatum 0.5 mm Identification Shoots grow in tufts or scattered, typically 1.5–4 cm tall, but only 0.25–0.5 mm wide, and often have a few branches. They are glossy, silvery green or yellowish above and pale brown below, with short (1 mm long), erect, concave leaves that overlap each other and appress the stem. The nerve reaches half or three-quarters of the way towards the leaf tip and sometimes even closer to the tip in var. julaceum; in var. concinnatum (A. concinnatum) the nerve reaches the tip. Bulbils quite often develop in the axils of leaves. Horizontal or drooping, cylindrical capsules about 3 mm long are rare from late spring to autumn. They have a short, yellow peristome, and are borne on a red seta about 2 cm long. The leaves surrounding the base of each seta are longer than the other leaves. Similar species Bryum argenteum (p. 596) also has pale, narrow shoots, but these are silvery white rather than silvery green or yellowish, and are never branched. Its leaves are not so oblong or tongue-shaped as in A. julaceum, and the capsule is 1.5 mm long rather than 3 mm. B. argenteum may also develop bulbils in its leaf axils, like A. julaceum. Plagiobryum zieri (p. 578) has wider shoots tinged pink below, and capsules 6–7 mm long. The leaves of Aongstroemia longipes (p. 363) are not clearly widest at the middle, and they narrow more abruptly to a blunt tip. -

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. -
