REFEREES (Regional & Specialist) See web-site: www.thebls.org.uk 2 British Lichen Society Bulletin no. 107 Winter 2010 Welcome to the Winter 2010 Bulletin, with notes and articles that are more varied than ever – a real reflection of the diversity of our membership. There must be something for everyone – persevere with the more erudite contributions and lighten up for the others! The Lichens in Gardens theme has continued throughout the year, with our members hobnobbing with the great and the good (come to think of it, they are the great and the good!) in some of the estates and gardens for which the country is famous. The 2010 Autumn meeting surveyed lichens at the National Botanic Garden of Wales, and members inspected the Society’s Library in its smart new location. The BLS is most grateful to NBGW and its library staff for hosting the collection and making it accessible to members. On a domestic note, lichen surveys of members’ own gardens have been coming in – there’s still time to make a list of your patch if you haven’t joined in yet. A major event over the summer was the 9th International Mycological Congress, held in Edinburgh at the beginning of August. Lichens and lichenologists featured strongly throughout much of the programme, reflecting the ever-closer links between study of lichenized and non-lichenized fungi. We do fit here more comfortably than with “cryptogamic plants” – whatever they are nowadays. The BLS awarded travel grants to a number of young lichenologists to present their work at IMC9, and short summaries of their contributions are included in this Bulletin. Special thanks to Heather Coffey for coordinating this, who was too modest to remind me that her own poster (presented with Lenore Fahrig) received a prize from the British Mycological Society. The congress was preceded by a well-watered (and well-whiskied) field meeting in Kintail and Skye, hosted by Brian and Sandy Coppins under the auspices of the IAL. The Autumn field meeting has already been mentioned, but other events included an excursion to the Isle of Man (also well-watered at times; lichen survey on Snaefell was challenging due to low clouds – it was difficult to see lichens, let alone identify them!). The summer meeting based in the Moray region was also memorable; accounts of both will follow in future issues. Looking forward, the AGM (on 14-16 January 2011) returns to London after its perambulations around the country. Don’t be put off by the thought of boring administrative announcements – the meeting will be spiced up by four fascinating presentations on lichen matters, including the biennial Swinscow Lecture, lichen tours around the NHM facilities, dinner (very important!) and a local field meeting the following day. More information at the back of this Bulletin. Next year there will, in addition to the usual field programme, a series of affordable one-day courses on lichen identification, subsidized by a grant to the BLS from OPAL. Don’t forget to put your name down – potentially the best £20 you will spend for a good while! And finally, your 2011 subscription is due shortly: see the end pages. Make sure you pay promptly, please, before you get targeted by the Membership Secretary!

The Midlands are now enjoying a dramatic period of re-colonisation in areas that were, until recently, considered as “lichen deserts”. Fieldwork was undertaken between 2008 and 2010 to record lichens throughout Sutton Park and these records allow some comparisons to be made with a personal list made by James in 1977 from a limited area of woodland and heathland. We present an annotated list of the 156 lichen taxa recently recorded and some of the changes that have been observed are discussed. The major habitats within the park and their associated lichens are described. Areas and features of particular interest are highlighted. Published surveys of specific sites in the Midlands and south-east England appear to be rather few and include the following papers. Brightman (1965) published an account of the lichens of Cambridge walls, Earland-Bennett (1976) and Laundon (1972, 1973 and 1977) produced several detailed surveys during the 1970s, while more recently James & Davies (2003) and Powell (2010) have published detailed accounts. Re-surveys of some of these sites have highlighted just how dramatically the lichen communities have changed and are still changing. The re-colonisation continues and it is to be hoped that many more sites will be surveyed allowing these important changes to be monitored. Introduction Sutton Park, the largest urban park in Europe covering 2400 acres, is situated just seven miles north of the centre of Birmingham (Coxhead, 2009). In contrast to most urban parks, which were created by town planners within the last 150 years, Sutton Park has an ancient history. A deer park was established in the twelfth century but the woodland and heathland that dominated the area were also managed to provide timber and grazing. In 1528 the Borough Charter was awarded by Henry VIII and the Corporation that was established took over responsibility for the park (Lea, 2003). This Corporation played an important role in preserving stable habitats by regulating the grazing, controlling the removal of wood and by banning ploughing. Some landscaping schemes to improve and beautify the landscape were attempted about 1800 but the park was still managed largely to give a good yield of timber and to provide grazing for cattle. During the 1800s the park became increasingly used for recreation, visitors could hire rowing boats, pay for pony rides and get refreshments. There were football and cricket pitches and a golf course was created but still the majority of the area consisted of heathland and woodland. By the second half of the twentieth century the emphasis was on the preservation of the park as a place of natural beauty. In 1997 it was designated as a National Nature Reserve, the only one in Warwickshire. The local inhabitants have had a long history of applying pressure to preserve Sutton Park. When the Corporation sold off parts of the park as farmland in the early sixteenth century the locals secured an injunction to prevent further sales. 2 Enclosure proposals put forward in 1778 were defeated by popular demand. Today public pressure still continues to influence the Park’s maintenance and priorities. Thus, the continued history of Sutton Park has allowed large areas of semi-natural habitat to survive in a relatively stable condition for many centuries. Methods The majority of lichen species were identified in the field. The more critical species were collected, if present in sufficient quantity, by the removal of a suitably small sample that would not endanger the colony. Chemical tests, microscopic examination and, where necessary, thin layer chromatography, have been employed to identify critical material. Saxicolous crusts are not easy to collect when growing on surfaces that cannot be damaged.

  • Appendix K. Survey and Manage Species Persistence Evaluation
    Appendix K. Survey and Manage Species Persistence Evaluation Establishment of the 95-foot wide construction corridor and TEWAs would likely remove individuals of H. caeruleus and modify microclimate conditions around individuals that are not removed. The removal of forests and host trees and disturbance to soil could negatively affect H. caeruleus in adjacent areas by removing its habitat, disturbing the roots of host trees, and affecting its mycorrhizal association with the trees, potentially affecting site persistence. Restored portions of the corridor and TEWAs would be dominated by early seral vegetation for approximately 30 years, which would result in long-term changes to habitat conditions. A 30-foot wide portion of the corridor would be maintained in low-growing vegetation for pipeline maintenance and would not provide habitat for the species during the life of the project. Hygrophorus caeruleus is not likely to persist at one of the sites in the project area because of the extent of impacts and the proximity of the recorded observation to the corridor. Hygrophorus caeruleus is likely to persist at the remaining three sites in the project area (MP 168.8 and MP 172.4 (north), and MP 172.5-172.7) because the majority of observations within the sites are more than 90 feet from the corridor, where direct effects are not anticipated and indirect effects are unlikely. The site at MP 168.8 is in a forested area on an east-facing slope, and a paved road occurs through the southeast part of the site. Four out of five observations are more than 90 feet southwest of the corridor and are not likely to be directly or indirectly affected by the PCGP Project based on the distance from the corridor, extent of forests surrounding the observations, and proximity to an existing open corridor (the road), indicating the species is likely resilient to edge- related effects at the site.

  • Global Biodiversity Patterns of the Photobionts Associated with the Genus Cladonia (Lecanorales, Ascomycota)
    Microbial Ecology https://doi.org/10.1007/s00248-020-01633-3 FUNGAL MICROBIOLOGY Global Biodiversity Patterns of the Photobionts Associated with the Genus Cladonia (Lecanorales, Ascomycota) Raquel Pino-Bodas1 & Soili Stenroos2 Received: 19 August 2020 /Accepted: 22 October 2020 # The Author(s) 2020 Abstract The diversity of lichen photobionts is not fully known. We studied here the diversity of the photobionts associated with Cladonia, a sub-cosmopolitan genus ecologically important, whose photobionts belong to the green algae genus Asterochloris. The genetic diversity of Asterochloris was screened by using the ITS rDNA and actin type I regions in 223 specimens and 135 species of Cladonia collected all over the world. These data, added to those available in GenBank, were compiled in a dataset of altogether 545 Asterochloris sequences occurring in 172 species of Cladonia. A high diversity of Asterochloris associated with Cladonia was found. The commonest photobiont lineages associated with this genus are A. glomerata, A. italiana,andA. mediterranea. Analyses of partitioned variation were carried out in order to elucidate the relative influence on the photobiont genetic variation of the following factors: mycobiont identity, geographic distribution, climate, and mycobiont phylogeny. The mycobiont identity and climate were found to be the main drivers for the genetic variation of Asterochloris. The geographical distribution of the different Asterochloris lineages was described. Some lineages showed a clear dominance in one or several climatic regions. In addition, the specificity and the selectivity were studied for 18 species of Cladonia. Potentially specialist and generalist species of Cladonia were identified. A correlation was found between the sexual reproduction frequency of the host and the frequency of certain Asterochloris OTUs.

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.

We specifically modelled spatial (across-site) heterogeneity in nucleotide frequencies, as models not incorporating 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 morphological and chemical data available.

Mycosphere 10(1), 310–489, Doi 10.5943/mycosphere/10/1/7 Abstract Leotiomycetes is regarded as the inoperculate class of discomycetes within the phylum Ascomycota. Taxa are mainly characterized by asci with a simple pore blueing in Melzer’s reagent, although some taxa have lost this character. The monophyly of this class has been verified in several recent molecular studies. However, circumscription of the orders, families and generic level delimitation are still unsettled. This paper provides a modified backbone tree for the class Leotiomycetes based on phylogenetic analysis of combined ITS, LSU, SSU, TEF, and RPB2 loci. In the phylogenetic analysis, Leotiomycetes separates into 19 clades, which can be recognized as orders and order-level clades.
