Abstract Lecanora caledonica is described as new to science. Molecular analyses show that it belongs to the L. intumescens group. It is also rather similar in appearance to L. intumescens, but differs mainly chemically in containing only atranorin and an unknown UV+ ice blue substance. There are also anatomical and morphological differences to the other species of the group. The new species has a pronounced oceanic distribution and is so far known only from western Norway and Scotland.

Alan Orange, who died on the 5th February aged only 67, will be missed more than he would ever have guessed by members of the British Lichen Society and lichenologists across the globe. He was an outstanding naturalist and taxonomist who made detailed studies of difficult groups of organisms, from lichens and bryophytes to mites. His knowledge of sterile crusts and aquatic lichens was unrivalled. He investigated every aspect of his chosen organisms, from their morphology to their chemistry and genetics, in order to describe them taxonomically and to assess their relationships to other lichens. Alan was born in Leeds but soon afterwards the family moved to Longhope in the Forest of Dean, where his surroundings provided plenty of opportunities for botanical and other exploration, often with his cousins Heather, Margaret and Stephen, and the family’s dogs. Early on he developed his botanical skills and his taste for sorting out difficult groups of organisms, and his parents complained that his collection of brambles had taken over his bedroom! He also showed exceptional talent as an artist, producing detailed botanical drawings and sketches which he continued for the rest of his life. He was accepted for his first degree in Science at Bristol University and then for a master’s degree in Pure and Applied Plant Taxonomy at Reading University, which he completed with distinction. After graduating in the early 1980s, he worked as a field botanist based at the University of Wales Institute of Science and Technology field centre at Newbridge-on-Wye, Powys. Tasked with undertaking botanical survey work on the upper reaches of the Rivers Wye, Usk, Severn and Teifi, this tall, immensely quiet but undoubtably talented character with hair below his waist rejected the proffered car to drive. Instead, a motorbike was acquired. As part of a very successful team, he helped lay the foundation for the science behind the statutory conservation of rivers and so began his own fascination with the hugely variable community of aquatic lichens. In 1977, while still an undergraduate, Alan was employed by the Nature Conservancy to survey the trees and flora in the permanent transects within Lady Park Wood in the Lower Wye Valley. The resulting records were so neat, thorough and accurate that they have been used as a basis for all subsequent recording. This, now possibly the largest and most enduring long-term study in Europe of how natural woodlands behave, would have been abandoned in its youth without Alan’s contribution. When he returned in 2014 to check the lichens for the Lady Park book (Peterken & Mountford 2017), he appeared to have no idea his work had been so significant. In 1986 he was appointed Curator of Lichens at the National Museum of Wales (NMW), now Amgueddfa Cymru-Museum Wales. His talent for illustration was quickly put to good use, producing a useful beginner’s guide to lichens on trees (Orange 1994). He held the post of curator until 2013 when he became
Alan Orange于2月5日去世，享年67岁。英国地衣学会的成员和全球的地衣学家将比他想象的更怀念他。他是一位杰出的博物学家和分类学家，对从地衣、苔藓植物到螨虫等困难的生物群进行了详细的研究。他对无菌结壳和水生地衣的了解是无与伦比的。他调查了他选择的生物的各个方面，从形态到化学和遗传学，以便对它们进行分类描述，并评估它们与其他地衣的关系。艾伦出生在利兹，但不久后全家搬到了迪恩森林的朗霍普，在那里，他的周围环境为植物和其他探索提供了很多机会，经常和他的表兄弟希瑟、玛格丽特和斯蒂芬以及家里的狗在一起。很早，他就培养了自己的植物学技能和分类困难生物群的品味，他的父母抱怨说，他的荆棘收藏占据了他的卧室！作为一名艺术家，他也表现出了非凡的天赋，创作了详细的植物画和素描，并一直延续到他的余生。他在布里斯托尔大学获得了第一个科学学位，然后在雷丁大学获得了纯粹和应用植物分类学硕士学位，并以优异成绩完成了学业。20世纪80年代初毕业后，他在位于波伊斯州怀伊河畔新桥的威尔士大学科技学院野外中心担任野外植物学家。负责在怀伊河、乌斯克河、塞文河和泰菲河上游进行植物调查工作，这个身材高大、非常安静但毫无疑问有天赋、头发在腰部以下的角色拒绝了提供的汽车。相反，一辆摩托车被收购了。作为一个非常成功的团队的一员，他帮助奠定了河流法定保护背后的科学基础，因此开始了他自己对水生地衣群落的着迷。1977年，当艾伦还是一名本科生时，他受雇于自然保护协会，调查下怀伊山谷Lady Park Wood内永久性样带的树木和植物群。由此产生的记录是如此整洁、彻底和准确，以至于它们被用作所有后续记录的基础。这可能是欧洲最大、最持久的一项关于天然林地行为的长期研究，如果没有艾伦的贡献，它在年轻时就会被放弃。2014年，当他回来为《公园夫人》一书（Peterken&Mountford，2017年）检查地衣时，他似乎不知道自己的工作如此重要。1986年，他被任命为威尔士国家博物馆（NMW）的地衣馆长，现为威尔士Amgueddfa Cymru博物馆。他的插图天赋很快得到了很好的利用，制作了一本有用的树上地衣初学者指南（Orange 1994）。他一直担任策展人一职，直到2013年成为博物馆名誉研究员和个体生物顾问。他为许多组织进行了地衣和苔藓植物的调查，包括威尔士自然资源局、皇家鸟类保护协会、Plantlife、国家信托基金和生态咨询公司。他在NMW数据库中收集的地衣包括7000多个标本，这些标本来自他在威尔士和英国的工作，以及对北欧国家和尼泊尔等其他国家的访问。他在威尔士完成的众多调查的收集和记录为威尔士的第一份清单（Woods&Orange，1999年）和后来的英国地衣和地衣真菌保护评估（Woods＆Coppins，2012年）提供了信息，这是关于需要保护的物种的宝贵信息来源。然而，他个人收藏的约15000个标本代表了他自2013年以来的大量工作，并被赠送给了NMW。该材料由地衣、真菌、苔藓植物和悬钩子属组成，将被纳入NMW数据库，供进一步研究。他与长期伴侣、硅藻学家Ingrid Jüttner博士结婚，Alan后来的大部分工作都是与Ingrid一起完成的。尽管他不容易找到，但他是一个善于沟通的人，有着古怪的幽默感，总是乐于帮助业余爱好者和专业人士解决分类学难题。如果你曾经和Alan合作过，你就学会了观察地衣群落，而其他地衣学家往往没有注意到这些群落。他广泛的物种识别技能使他在2008年为联合自然保护委员会撰写了一份具有里程碑意义的报告，描述了英国高地苔藓植物和地衣群落的范围（Orange 2008）。这些群落已从《国家植被分类》卷中删除。这份内部报告值得全面公布。 他对无菌外壳的了解和欣赏导致了11篇关于鳞翅目地衣的论文，他在论文中表明，这些看似简单、没有皮层、没有有性繁殖的生物产生了一系列代谢产物，使它们能够在全球广泛的栖息地中发挥作用。尽管这需要实验室的技术专业知识，但他对该领域细节的眼光很敏锐，他结合了形态学、简单的化学测试和紫外线反应，使地衣群落的其他成员能够获得这项工作（Orange 1995），并在《大不列颠和爱尔兰的地衣》（Smith等人，2009）的版本中获得了更详细的信息。他在《大不列颠和爱尔兰的地衣》中贡献了许多地衣特征的插图。2006年，他为英国地衣学会编写了一本手册

Abstract A novel lichen species occurring on rocks was collected from three different localities within Deosai National Park, Gilgit-Baltistan, Pakistan. Phylogenetic analyses of the nrDNA ITS and nuLSU regions revealed that it clustered within the genus Anamylopsora. Further chemical and morpho-anatomical analyses confirmed its uniqueness, and it is described here as a new species under the name A. pakistanica. The distinguishing characters are: an irregularly squamulose appressed thallus on rocks without rhizines; an epinecral layer up to 25 μm thick; ascospores that are hyaline, simple, thick-walled with a smooth surface; septate paraphyses with a pigmented apical cell in a gel-like matrix; globose to subglobose pycnidia with hyaline and bacilliform pycnidiospores. In particular, the species is distinguished from other members of the genus by morpho-anatomical features including the coloration of the thalli, the presence of a thick lower cortex (up to 100 μm), and the presence of simple, thick-walled ascospores. Specimens were found at altitudes up to 4587 m, the highest elevation yet reported for Anamylopsora. A key and comparison to all existing species of the genus Anamylopsora is also given.

Abstract Four species of Porpidia are newly reported from China, including one species new to science (Porpidia crystallina) and three records (Porpidia umbonifera, P. seakensis and P. cf. contraponenda) new to China. Porpidia crystallina is characterized by a macrocarpa-type exciple containing crystals, a Cinereorufa-green epihymenium, large ascospores and a lack of secondary metabolites. Morpho-anatomical, chemical and phylogenetic analyses were carried out to elucidate the placement of the species and to support the delimitation of the new taxon. Detailed taxonomic descriptions, ecological and chemical characters, and illustrations are provided for each species. A key to all known Chinese Porpidia species is also provided.

Abstract The type species of Squamarina has two varieties, S. gypsacea var. gypsacea and S. gypsacea var. subcetrarioides. In this study, a phylogenetic and taxonomic analysis of these two varieties shows that S. var. subcetrarioides merits treatment as a species separate from S. gypsacea. Therefore, we raise this variety to species level as S. subcetrarioides (Zahlbr.) Y. Y. Zhang. Squamarina subcetrarioides is phylogenetically not closely related to S. gypsacea and differs from that species in the thallus forming rosettes when young, later becoming cracked and irregular in outline, and consisting of numerous small squamules.

Abstract A new lichen species, Lecanora zeorina Li J. Li & Printzen is described here from the south-west of China. Lecanora zeorina is characterized by its somewhat areolate-squamulose thallus, zeorine to lecanorine apothecia, an epihymenium without crystals around expanded paraphyses tips, an amphithecium with large calcium oxalate crystals and the production of atranorin. A new combination, Lecanora crystalliniformis (B.G. Lee & Hur) Li J. Li & Printzen, is based on Protoparmeliopsis crystalliniformis B.G. Lee & Hur, which was described as a new species from South Korea. Collections from China are almost identical in morphology and chemistry, and are phylogenetically closely related. Phylogenetic reconstructions based on ITS and mtSSU suggest that these two lecanoroid species belong in Lecanora s. str. where they form a sister group to sorediate species such as L. barkmaniana Aptroot & Herk and L. variolascens Nyl. Detailed descriptions, discussions, distributions and phylogenetic trees, based on multiple collections, are presented.
摘要记述了中国西南地区一新种Lecanora zeorina。Lecanora zeorina的特点是其有点像鹅毛状鳞状的菌体，zeorine到lecanorine的药液，在膨大的鞘尖周围没有晶体的膜层，具有大的草酸钙晶体的amphithecium和atanorin的产生。一个新的组合，Lecanora crystalliniformis (B.G. Lee & Hur) Li J. Li & Printzen，是基于原parmeliopsis crystalliniformis B.G. Lee & Hur，被描述为来自韩国的新种。来自中国的集合在形态和化学上几乎相同，并且在系统发育上密切相关。基于ITS和mtSSU的系统发育重建表明，这两个lecanoroid物种属于Lecanora s. str.，它们是L. barkmaniana Aptroot & Herk和L. variolascens Nyl等物种的姐妹类群。详细的描述，讨论，分布和系统发育树，基于多个集合，提出。

Abstract This study re-examined the status of species of Diorygma Eshw. known from the Western Ghats using an integrative taxonomy approach that includes morphological and chemical data, as well as multigene phylogenetic analyses. Prior to this work, the two species D. karnatakense and D. dandeliense were distinguished primarily on lirellae morphology (branching pattern) and the number of ascospores per ascus. Our study of the morphology, chemistry and molecular phylogeny (mtSSU, LSU and RPB2) of freshly collected samples and re-examination of type material suggests that both names should be synonymized. Consequently, D. karnatakense is accepted as the correct name, with D. dandeliense as a newly proposed synonym. Phylogenetically, D. karnatakense is allied to D. antillarum and D. hieroglyphicum.

Abstract Microsatellite markers can provide valuable information about gene flow and population history. We developed and tested new microsatellites for the nitrophilic lichenized fungus Xanthoria parietina and studied its genetic diversity and structure within the urban area of Munich, Bavaria. We compared its local genetic pattern with that of its photobiont partner Trebouxia decolorans, for which existing microsatellites were applied. For comparison, a reference site with clean air was included in the sampling. We found support for three genetic clusters in the fungus X. parietina, which occurred intermingled in collecting sites. There was a high degree of admixture within fungal populations and individuals, and analysis of molecular variance revealed a lack of population structure in the mycobiont. The Trebouxia photobiont, in contrast, exhibited structured populations which grouped into two to five genetic clusters, and individuals showed less admixture than in the mycobiont. This indicates that the two lichen partners differ in their ability to move around in the landscape. The microsatellite markers we report are polymorphic and are suitable for population genetic studies.

We developed and tested new microsatellites for the nitrophilic lichenized fungus Xanthoria parietina and studied its genetic diversity and structure within the urban area of Munich, Bavaria.
