Recent literature on lichens—202

Alstrup, V. & A. Aptroot. 2005. Pyrenocarpous lichens from Tanzania and Kenya. Cryptogamie, Mycologie 26(3): 265– 271. [32 taxa reported, most new country records; 12 taxa new to Africa.] Aptroot, A. & V. Wirth. 2006. A saxicolous Arthothelium from the Namib desert. Lichenologist 38(2): 123–126. [New: Arthothelium desertorum sp. nov. (Namibia) on rocks.] Aragon, G., V. J. Rico & R. Belinchon. 2006. Lichen diversity from Cazorla, Segura and Las Villas Biosphere Reserve (SE Spain). Nova Hedwigia 82(1–2): 31–50. [497 species in 125 genera; new to Spain: Involucropyrenium waltheri, Placynthium asperellum, Stangospora deplanata, Verrucaria cinereoviridescens and V. polysticha; 267 taxa are new to Jaen province.] Arup, U. 2006. A new taxonomy of the Caloplaca citrina group in the Nordic countries, except Iceland. Lichenologist 38(1): 1–20. [Treatment of 5 species in the group with a key, descriptions, distribution maps, and color photographs; supporting data includes analysis of ITS ribosomal DNA; new: Caloplaca arcis (Poelt & Vězda) comb. nov., C. dichroa sp. nov.; other species include C. phlogina, C. citrina and C. flavocitrina (mentioned also from Pennsylvania).] Baloch, E. & M. Grube. 2006. Evolution and phylogenetic relationships within Porinaceae (Ostropomycetidae), focusing on foliicolous species. Mycological Research 110(2): 125–136. [Authors recognize 4 main clades. ‘‘The genus Porina as understood by all recent concepts is paraphyletic, and Trichothelium is nested within the Porina nitidulagroup. Species-specific associations with morphologically different trentepohlioid photobionts mapped on the tree suggest that closely related mycobiont species switch between different types of algae.’’] Barreno, E. & S. Perez-Ortega. 2005. The UNESCO-MAB Reserve of Muniellos (Spain, Asturias), an example of high lichen diversity in Europe and the success of conservations strategies. Flora Mediterranea 15: 453–460. [474 lichens and 28 lichenicolous fungi in the 5542 hectare reserve; no nitrophytic habitats were found in this ancient woodland; rare finds include Epigloea renitens, Gyalideopsis calabrica, Cystobacidium hypogymniicola, Rhizocarpon caesium and Porpidia flavicunda.] Beckett, R. P., N. Mayaba, F. V. Minibayeva & A. Alyabyev. 2005. Hardening by partial dehydration and ABA increase desiccation tolerance in the cyanobacterial lichen Peltigera polydactylon. Annals of Botany 96(1): 109–115. [Test material from KwaZulu-Natal, South Africa. ‘‘Results indicate that the photobiont of P. polydactylon possesses inducible tolerance mechanisms that reduce desiccationinduced damage to carbon fixation, and will therefore improve the supply of carbohydrates to the whole thallus following stress. In this lichen, ABA is involved in signal transduction pathways that increase tolerance of the photobiont.’’] Behera, B. C., N. Verma, A. Sonone & U. Makhija. 2005. Antioxidant and antibacterial activities of lichen Usnea ghattensis in vitro. Biotechnology Letters 27(14): 991–995. [‘‘Hence, U. ghattensis deserves to be explored for its bioactive molecules. There is however, a need to improve the growth rate of the cultured tissue in the laboratory to harvest large quantities of cells and thus metabolites.’’] Bellemere, A. & C. Bellemere. 2005. «Pyrenomycetes sensu lato» elements de bibliographie recente. Annees 2003 et 2004 et complements annees 2001 et 2002. Cryptogamie, Mycologie 26(2): 149–185. [A few lichen/lichenicolous papers included.] Bennett, J. P. 2006. What do we know about Wisconsin lichens? Evansia 23(1): 13–18. [‘‘In conclusion, the lichen picture for Wisconsin is incomplete because collecting has not been performed evenly across the state. We do know, however, * The cumulative database for this series is available in searchable form on the World Wide Web at http://www.toyen.uio.no/ botanisk/bot-mus/lav/sok_rll.htm.
