Enterographa ducouretiana is described as new to science from New Caledonia. It is characterized by a foliicolous habit, ascomata immersed in a pseudostroma, a dark purple hypothecium, and (3–)5-septate ascospores of (16–)20.5(–24) × (2.5–)2.9(–3.5) μm with a distinct gelatinous sheath of 1.5(–2) μm.

Three new species of Arthoniales are described from Cape Verde: Ingaderia dendritica, with ascomata formed of richly branched-dendroid lirellae and containing erythrin; Sparria caboverdensis, with small stroma-like ascomata and ascospores with 3–7 transverse septa; and Syncesia miesii, with an I− thallus, a tomentose hymenial disc, and a chemistry with fatty acids only. Phylogenetic analyses using nuLSU and RPB2 sequences reveal the placement of ...

335 species of lichens and 24 species of lichenicolous fungi were recorded during inventories carried out between 2020 and 2023 in the section of the Semois valley between Bouillon and Bohan. Nineteen species are new to Belgium: Abrothallus caerulescens, Arthonia digitatae, A. graphidicola, Bacidina piceae, Chaenothecopsis ochroleuca, Cresponea premnea, Dirina fallax, Lecanora cenisia, Lichenostigma alpinum, Mycoblastus caesius, Porina collina, ...

Description of the new species Corticifraga ramalinae P. Pinault, Ertz et Cl. Roux sp. nov., close to C. peltigerae, from which it differs by its parasitism on the thallus (rarely the apothecia) of Ramalina fraxinea where it does not induce galls but which its discolors, by its spores (0)3–septate, a little longer and less wide, mostly 17,5 – 25,5 × 4 – 5 μm, and by its distinct phylogenetic position (its sequence) (sister species of C. ...

Sclerococcum is a species rich lichenicolous genus in Ascomycota. However, many species of Sclerococcum have been described based only on morphology. This study provides sequences for the large-subunit ribosomal RNA (LSU), internal transcribed spacer (ITS) and mitochondrial small-subunit ribosomal RNA (mtSSU) for the first time for Sclerococcum simplex, and the first geographical record of the genus from China. Phylogenetic analyses confirmed ...

Background and aims – Despite the publication of a recent checklist for Mauritius, a small archipelago in the south-western Indian Ocean, our knowledge of the lichen flora of this region remains incomplete. The present contribution is part of an ongoing study of lichen diversity of the islands of Mauritius and Rodrigues. It aims to unravel the diversity of the genus Porina s.l. on these islands and to improve the taxonomy and the phylogeny of ...

Laboulbeniomycetes is a class of fungi that have obligate associations with arthropod hosts, either for dispersal (order Pyxidiophorales) or as biotrophic parasites (orders Herpomycetales and Laboulbeniales). Here, we focus on Herpomycetales and Laboulbeniales, which include fungi that form thalli, 3-dimensional, multicellular units of 1000 s of cells. Based on recently published data regarding patterns of speciation, we present the ...

Bacterial biofilms have been described on a number of fungal taxa. These microbial communities are of interest both from an ecological and a biotechnological point of view, as they have been shown to play a role in biodegradation and biosynthesis. This study is the first to show the presence of biofilms on thallus surfaces of Laboulbeniales, an order of fungi that have biotrophic associations with arthropod hosts. Scanning electron microscopy ...

Altogether 322 taxa of lichens and lichenicolous fungi are reported from Ecuador of which many are probably new records for the country. These include five species which are described as new to science: Bacidia andina, Bacidina pulverula, Distopyrenis epidiorygma, Pertusaria lucidotetra and P. pseudoparnassia. From the separately treated genera Lepra and Pertusaria, 12 species are recorded for Ecuador and/or other Neotropical countries. Notes on ...
