Gerhard Neuwirth's scientific contributions

... The genus Tapellaria [17] forms black, lecideine apothecia, anastomosing paraphyses, and campylidia producing filiform conidia. It is a predominantly foliicolous genus (25 species) with only a small number of the species growing on bark [18]. Most of the species are known from Neotropics, but Tapellaria parvimuriformis was newly described from East Asia [11]. ...

... With increasing knowledge and available material, it became clear, however, that Redinger's pioneering work covered less than half of the actual diversity. Major modern contributions were provided, e.g., by Staiger (2002), Frisch & Kalb (2006), Lücking et al. (2009, 2016), Rivas Plata et al. (2010, Sipman et al. (2012), Lücking (2014), Feuerstein et al. (2014Feuerstein et al. ( , 2022a, and Neuwirth et al. (2017). The high diversity was accentuated by the description of many new species from a two-week field trip to Rondônia in 2012 ). ...

... Recent studies on the diversity of lichen-forming fungi in Thailand have dramatically increased our knowledge of these organisms in Southeast Asia, with numerous new records and new species discovered in a number of different habitats, including coastal forests (Aptroot et al. 2007;Kalb et al. 2012Kalb et al. , 2016aKalb et al. , 2016bKantvilas et al. 2010;Luangsuphabool et al. 2016aLuangsuphabool et al. , 2016bNaksuwankul et al. 2016;Neuwirth et al. 2014Neuwirth et al. , 2016Papong and Lumbsch 2011;Papong et al. 2014;Pitakpong et al. 2015;Rangsiruji et al. 2016;Sutjaritturakan and Kalb 2015;Buaruang et al. 2017). ...

... Notes: Morphologically, Myriostigma laxipunctata is similar to Myriostigma irregulare (Lücking, Aptroot, Kalb & Elix) Frisch & G. Thor, but the latter has radiately elongated ascigerous areas, short-stalked asci and psoromic acid, subpsoromic acid, 2 ′ -O-demethylpsoromic acid and confluentic acid as secondary metabolites [31]. In addition, Myriostigma laxipunctata is similar to Cryptothecia stockeri G. Neuwirth & Aptroot in having a firmly attached thallus and brown punctate ascigerous areas, but C. stockeri has a brown linear shaped prothallus, smaller ascospores (25-40 × 12-15 µm) and psoromic acid as a secondary metabolite [35]. ...

... The speciation continuum is probably also at the root of the overall poor results of the automatic species discovery strategies we used in this study. Automatic species discovery strategies based on singlelocus datasets such as ABGD, ASAP, GMYC or bPTP have been widely used to address the taxonomy of diverse groups of lichen-forming fungi (Kraichak et al. 2015, Del-Prado et al. 2016, Pérez-Ortega et al. 2016, Simon et al. 2018. It is known that these automatic strategies have limitations. ...

... Foliicolous lichens are one of the most widespread groups of lichenized fungi in tropical South-East Asia, but studies on these lichens in this region are comparatively few (Krempelhuber 1874;Müller 1890a, b;Nylander 1891;Vainio 1920Vainio , 1923Santesson 1952;Vězda 1977;Aptroot & Sipman 1993;Lücking & Sérusiaux 1997;Boonpragob et al. 1998;Papong et al. 2007Papong et al. , 2009Sérusiaux et al. 2008;Nguyen et al. 2010Nguyen et al. , 2011Neuwirth et al. 2014;Naksuwankul & Lücking 2019), and no modern systematic inventory has yet been undertaken. ...

... Lichen substances were analyzed by standard technique of thin-layer chromatography in solvent systems A, B, C and G (Orange et al. 2001). The nomenclature follows mostly Fałtynowicz and Kukwa (2006), excluding lichens from Teloschistaceae family (Arup et al. 2013) and genera: Alyxoria (Ertz & Tehler 2011), Caeruleum (Arcadia & Knudsen 2012), Circinaria (Nordin et al. 2010), Graphis (Neuwirth & Aptroot 2011), Varicellaria (Schmitt et al. 2012), Violella and Zwackhia (Ertz & Tehler 2011), and species: Brianaria sylvicola (Ekman & Svensson 2014), Cladonia floerkeana (Santesson et al. 2004), Lecanora filamentosa (Palice et al. 2011), L. pannonica (Brodo et al. 1994), L. saxicola (Laundon 2010), Lepraria finkii (Lendemer 2011), Melanelixia glabratula (Arup & Sandler Berlin 2011), Punctelia jeckeri (Kalb 2007), Rinodina oleae (Santesson et al. 2004) and Usnea dasopoga (Arcadia 2013). ...

... The species has been reported in the Neotropics from Brazil, Colombia, Costa Rica and the USA (Florida), and elsewhere from Africa ( Rwanda & Zaire), Australia and Taiwan ( Vězda 1979;Kalb & Vězda 1988;Kalb 1996;Aptroot & Sparrius 2003;Breuss & Neuwirth 2007;Lücking et al. 2007;Sipman et al. 2008). Specimen examined: BOLIVIA. ...

... Graphis mellis-insulae is morphologically similar to G. breussii Neuwirth and Lücking with which it shares prominent lirellae with striate labia and complete thalline margin, but the latter differs in having completely carbonized excipulum, narrower ascospores (9-12 lm) and contains only norstictic acid (Neuwirth and Lücking 2009). ...
