Recent studies of the global diversity lichenized fungal family Graphidaceae suggest that there are a large number species remaining to be discovered. No less than 640 have been described since 2002, including 175 new introduced in collaborative effort single issue this journal. These findings largest tropical crustose lichens may an even higher Parmeliaceae. To estimate whether discovery is significant step forward cataloguing extant family, we employed parametric method predict richness...
Protecting aboveground carbon stocks in tropical forests is essential for mitigating global climate change and assumed to simultaneously conserve biodiversity. Although the relationship between tree diversity generally positive, remains unclear consumers or decomposers. We assessed this multiple trophic levels across of life (10 organismal groups, 3 kingdoms) lowland rainforests Congo Basin. Comparisons regrowth old-growth evinced expected positive trees, but not other groups. Moreover,...
We provide an updated skeleton phylogeny of the lichenized family Graphidaceae (excluding subfamily Gomphilloideae), based on three loci (mtSSU, nuLSU, RPB2), to elucidate position four new genera, Aggregatorygma, Borinquenotrema, Corticorygma, and Paratopeliopsis, as well placement enigmatic species Diorygma erythrellum, Fissurina monilifera, Redingeria desseiniana. Based resulting topology, in addition tribes described previously, we recognize further Graphidoideae: Acanthothecieae...
We present an updated 3-locus molecular phylogeny of tribe Ocellularieae, the second largest within subfamily Graphidoideae in Graphidaceae. Adding 165 newly generated sequences from mitochondrial small subunit rDNA (mtSSU), nuclear large (nuLSU), and DNA-directed RNA polymerase II (RPB2), we currently distinguish 218 species among sequenced material, including outgroup. This corresponds to almost half at this point recognized tribe. The include 23 described one genus published elsewhere...
Background and aims – The Arthoniaceae form a species-rich family of lichenized, lichenicolous saprophytic fungi in the order Arthoniales. As part taxonomic revisions African Arthoniaceae, number species assignable to genus Synarthonia were collected sequenced. present study at placing phylogeny for first time clarifying its circumscription. Methods Nuclear (RPB2) mitochondrial (mtSSU) DNA sequences from freshly specimens obtained analysed with phylogenetic Bayesian maximum likelihood (ML)...
Abstract Six new species of foliicolous lichenized fungi are described as to science from lowland rainforest in the Congo Basin: Bapalmuia serusiauxiana Van den Broeck, Lücking & Ertz ( Pilocarpaceae ) characterized by (7–)15(–19)-septate ascospores (40–)50–65(–72)×1·5–2·5 μm, Microtheliopsis ramazaniana Microtheliopsidaceae 1-septate 13–16×3–5 Phylloblastia verheyeniana Verrucariaceae 3-septate 13–15(–17)×3·0–4·5 Porina duduana Porinaceae 11·0–14·5×2·5–3·0 perithecia 130–150(–170) μm...
Cryptophaea, a new corticolous lichen genus, is described from the Congo basin as belonging to cryptothecioid Arthoniaceae. It characterized by (1) maculiform, tomentose, brownish ascomata lacking distinct exciple, (2) absence of hamathecium paraphysoids, (3) byssoid crustose thallus with trentepohlioid photobiont, (4) greyish brown (sub)muriform ascospores and (5) presence parietin, an anthraquinone, absent in other At this moment genus represented only one species, Cryptophaea phaeospora...
Three new species of Graphidaceae are described as to science from tropical Africa: Graphis aptrootiana Van den Broeck, Lücking & Ertz and Redingeria desseiniana the Democratic Republic Congo, G. vandenboomiana Ertz, Broeck Reunion. A key is presented all known Redingeria. The lichenicolous fungus Etayoa trypethelii mentioned Central Africa.
Abstract Heterocyphelium is a mazaediate genus containing single species, H. leucampyx . The species was originally described from Cuba within the Trachylia ( Arthoniales , Arthoniaceae ) and later placed in various genera of collective order Caliciales s. lat. For past three decades, considered an orphaned incertae sedis Ascomycota, since morphology alone could not resolve its systematic position. In this study, we added molecular data with aim resolving uncertainty. Bayesian maximum...
Background – As part of taxonomic revisions tropical African lichens, two species Piccolia are described as new to science while a third unknown one collected in the Solomon archipelago was kindly send us by second author. Material and Methods Morphology studied using stereo light microscope. Chemistry with spot tests TLC. Key results P. congolensis Van den Broeck, Aptroot & Ertz sp. nov. twice Democratic Republic Congo is characterized notably thallus KC+ orange soralia. The material...
Abstract A new species of Synarthonia , S. leproidica is described from Luxembourg. Phylogenetic analyses mtSSU and RPB 2 sequences were used to determine the generic affiliation this sterile species. differs all other genus by combination a leproid thallus production psoromic acid. It sister muriformis in our phylogenetic analyses. The discovery suggests that strictly sorediate lichen might have been overlooked Europe, even intensely explored countries such as further confirm placement...
Enterographa confusa is described as new to science from Cuba. It characterized by a lichenicolous habit, punctiform ascomata immersed in the host thallus, (6–)8-spored asci and 3-septate ascospores of 17–23 × (2.5–)3 µm with distinct gelatinous sheath 1.5(–2) µm. The species was discovered chance thallus type material Arthonia ochraceella, which lectotypified here. A detailed description this latter also provided. can be easily overlooked because its tiny pale similar colour those lichen....
Four species of Arthothelium from Africa and Socotra are described as new to science: atrorubrum Madagascar, characterized by irregularly rounded blackish ascomata with a deeply red hypothecium submuriform ascospores; aurantiacopruinosum the Democratic Republic Congo, black, stellate, orange pruinose muriform ascospores two larger terminal cells; frischianum brownish-black minute irregular remnants thallus one cell; miesii (Yemen), thick thallus, immersed, stellate cerebriform, brownish,...
