A new species of Lithothelium (lichenized Ascomycota, Pyrenulaceae) from the Tarkine region, north-western Tasmania

Abstract

Lithothelium kantvilasii sp. nov. (lichenized Ascomycota, Pyrenulaceae) is described from cool-temperate rainforest in the Tarkine region of north-western Tasmania, Australia. It has a whitish and largely endophloeodal thallus, minute, solitary perithecioid ascomata with an apical ostiole and small, hyaline 3-septate ascospores. A key is provided to the seven species of Lithothelium that occur in Australia and Christmas Island (an Australian territory).

Taxonomy and new distributional records of corticolous manglicolous microlichens in Bangrin Marine Protected Area, Philippines

“…Their cylindrical ascus has a prominent spherical ocular chamber but is reported to be invaginated or sagittiform in some species. In the Pyrenulaceae family, there are at least 33 Lithothelium species in the reported pyrenocarpous lichens (Aptroot, 2006;Gueidan, Aptroot, Cáceres & Binh, 2016;McCarthy, 2015). The species of Lithothelium documented in BMPA was also reported in Puerto Rico and South Africa (Consortium of Lichen Herbaria, 2023; The Catalogue of Life Partnership, 2018).…”

“…Taxonomic keys for Bacidia (Ekman, 1998;Ekman, 2001;Gerasimova, Ezhkin & Andreas, 2018;Lee & Hur, 2022), Graphis (Lucking, Archer & Aptroot, 2009;Peña, Lücking, Miranda-Gonzalez & delos Angeles Herrera-Campos, 2014), Lecanora (Brand, 2008;Papong, Boonpragob & Lumbsch, 2011;Santos, Aptroot, Lücking & Cáceres, 2023), Lithothelium (Aptroot, 2021;Berger, LaGreca & Aptroot, 2016;McCarthy, 1996;McCarthy, 2015), and Pyrenula (Aptroot, 2021) were used to determine the lichen species. An identification key for the corticolous manglicolous crustose lichens in the Bangrin Marine Protected Area was prepared.…”

New Zealand Lithothelium (Pyrenulaceae) — description of a new species Lithothelium kiritea sp. nov., with notes on L. australe

“…As the Aotearoa / New Zealand lichenized mycobiota is biogeographically strongly linked to Australia (Galloway, 2007), we examined Lithothelium there. Currently, seven species of Lithothelium are recognised in Australia and its neighbouring islands (Aptroot, 2009;McCarthy, 1996McCarthy, , 2001McCarthy, , 2015. From all these, L. Ecology: Lithothelium kiritea has so far only been collected from a single phorophyte, Cordyline aus tralis (Figs 1, 2), on which it is often the only species of lichen inhabiting the bark, at least until host trees reach a level of maturity where other species of lichen begin to colonise and displace it, at which point it can be sometimes still seen on smaller canopy branches.…”

Two new species of the lichenized genus Lasioloma (Byssolomataceae) from Asia

“…A total of eleven species of Lasioloma have been reported and a key has also been produced for these species, except L. corticola (McCarthy 2020; Lücking et al . 2021), but there has been little recent progress in research on this genus in Asia and so the present study aims to reduce this knowledge gap.…”

“…Foliicolous species are characterized by a woolly prothallus, a dispersed to continuous thallus, and a pilose apothecial margin; corticolous species usually lack a woolly prothallus and their thalli are usually continuous. All known species produce campylidia and branched conidia (Santesson & Lücking 1999;Lücking & Sérusiaux 2001;Breuss 2002;Lücking 2008;van den Boom et al 2018;McCarthy 2020;Lücking et al 2021).…”
