Kaasalainen U., Biermann L., Mollel N., Schmidt A. & Hemp A. (2022): Peltigera (Lecanoromycetes) on Mt Kilimanjaro, East Africa - Lichenologist, 54(5): 231-243

Tropical mountain forests are hotspots of biodiversity that are widely threatened by human population pressure and climate change. However, the cryptogamic species richness of many tropical mountain regions is insufficiently known, the poorly understood biodiversity of tropical African lichens being a prime example. To study the diversity of the genus Peltigera (Ascomycota, Lecanoromycetes) in East Africa, we studied lichens in a wide range of habitats on the slopes of Mt Kilimanjaro in Tanzania. … Read more...

Kirika P., Lumbsch H., Huéscar E., Quedensley T. & Divakar P. (2022): Canoparmelia texana (Parmeliaceae, Ascomycota) consists of two independent lineages - Lichenologist, 54(5): 245-251

Recent studies have demonstrated that species boundaries among the lichen-forming fungi are in need of revision with the discovery of cryptic species in numerous clades, especially in parmelioid lichens. Here we focus on addressing the species boundaries in Canoparmelia texana, a sorediate species with a pantropical distribution that extends into temperate regions. We extracted DNA sequences of the nuclear ribosomal internal transcribed spacer region (ITS), large subunit (nuLSU) and mitochondrial … Read more...

Kitara N., Munishi P. & Scheidegger C. (2022): Distribution of Lobaria pulmonaria (L.) Hoffm. in Mt Kilimanjaro and Mt Meru forests: altitudinal range and specificity to substratum tree species - Lichenologist, 54(5): 331-341

In this study, we sampled L. pulmonaria thalli from Mt Kilimanjaro and Mt Meru, Tanzania. Across all sampled tree species, a range of 1–35 thalli of L. pulmonaria were counted per trunk (up to 5 m above ground level), with sampling distributed across 13 (c. 1 ha) plots located in the sub-alpine to montane forest altitudinal gradients of Mt Kilimanjaro and Mt Meru. Descriptive analyses were performed to determine the association of L. pulmonaria with particular host trees among the study sites and … Read more...

Medeiros I. & Lutzoni F. (2022): Contribution to a modern treatment of Graphidaceae biodiversity in South Africa: genera of tribe Graphideae with hyaline ascospores - Lichenologist, 54(5): 253-270

Additions and corrections are provided for the South African species of Graphidaceae tribe Graphideae with hyaline ascospores. Allographa oldayana I. Medeiros sp. nov. is described as new to science based on morphological, chemical and molecular data. The new species is characterized by lirellae with striate labia and a complete thalline margin, a completely carbonized excipulum, large, muriform ascospores, and the presence of hirtifructic acid. Allographa consanguinea (Müll. Arg.) Lücking, A. … Read more...

Mkhize K., Minibayeva F. & Beckett R. (2022): Adaptions of photosynthesis in sun and shade in populations of some Afromontane lichens - Lichenologist, 54(5): 319-329

Photosynthetic organisms have evolved a great variety of mechanisms to optimize their use of sunlight. Some of the clearest examples of adaptations can be seen by comparing photosynthesis in different species and in different individuals of the same species that grow under high and low light levels. While the adaptations of sun and shade higher plants have been relatively well studied, much less information is available on the photobionts of lichenized Ascomycetes. An important adaptation that can … Read more...

Nadel M. & Clerc P. (2022): Notes on the genus Usnea Adans. (lichenized Ascomycota, Parmeliaceae) from the islands of São Tomé and Príncipe in tropical West Africa - Lichenologist, 54(5): 271-289

An investigation of the genus Usnea, in the biodiversity hotspot of the Republic of São Tomé and Príncipe in tropical West Africa, is presented here. Fifteen species, or species aggregates, were recorded for the islands: Usnea articulata aggr., Usnea baileyi (Stirt.) Zahlbr., Usnea beckeri P. Clerc & Nadel, Usnea bicolorata Motyka, Usnea erinacea aggr., Usnea exasperata (Müll. Arg.) Motyka, Usnea firmula (Stirt.) Motyka, Usnea krogiana P. Clerc, Usnea longiciliata P. Clerc & Nadel, Usnea nodulosa … Read more...

Temu S., Clerc P., Nadel M., Tibell L., Tibuhwa D. & Tibell S. (2022): Molecular, morphological and chemical variation of the Usnea pectinata aggregate from Tanzania, São Tomé and Príncipe - Lichenologist, 54(5): 291-298

This study investigated the molecular, chemical and morphological variation in the Usnea pectinata aggregate using 42 specimens, 22 from Tanzania and 20 from São Tomé and Príncipe. A total of 31 sequences (13 ITS, 13 nuLSU and 5 RPB1) were generated. The results are presented in two phylogenies: first a three-markers ‘backbone’ phylogeny for the U. pectinata aggregate, where six distinct, strongly supported subclades indicate considerable genetic variation in the dataset; and second, an ITS … Read more...

Marcano V. (2022): Eight new species of lichenized Basidiomycota in the genera Acantholichen, Cyphellostereum and Dictyonema s.str. (Agaricales, Hygrophoraceae) from northern South America - Phytotaxa, 574(3): 199–225

A study of Acantholichen P.M. Jørgensen, Cyphellostereum D.A. Reid and Dictyonema s.str. C. Agardh ex Kunth from the Venezuelan Andes (Sierra Nevada de Mérida) and the Guayana Highlands (Alto Orinoco) revealed the presence of eight species new to science, viz., Acantholichen dendroideus V. Marcano, Cyphellostereum mucuyense V. Marcano, Dictyonema andinum V. Marcano, D. duidense V. Marcano, D. laurae V. Marcano, D. subinvolutum V. Marcano, D. subsericeum V. Marcano and D. umbricola V.
