... Chapsa asteliae differs in amyloid and shorter ascospores (30-80 μm) (Kantvilas and Vězda 2000;Mangold 2008). Astrochapsa elongata differs from C. murioelongata in having shorter ascospores (40-65 μm) and less longitudinal septa per segment (0-1) (Poengsungnoen et al. 2019). Chapsa patens differs from C. murioelongata chiefly in the single-spored asci and broader ascospores (22-35 μm) (Frisch et al. 2006). ...

... Nested placement at genus level is particularly cumbersome, as it affects the binomial if paraphyletic genera are not accepted. However, often such nested placement is an artifact of taxonomic resolution; for instance, the genus Heterodea, nested within Cladia in Cladoniaceae (Parnmen et al., 2010), was subsequently resurrected as a monophyletic clade after splitting Cladia s.lat. into smaller entities (Kraichak et al., 2018;Stenroos et al., 2019). ...

... Subsequently, through collaborations between Thai and international lichenologists, several publications have documented the large diversity of lichens from various parts of Thailand (e.g., Jariangprasert & Anusarnsunthorn 2005, Aptroot et al. 2007, Lumbsch et al. 2011, Mongkolsuk et al. 2015, Naksuwankul et al. 2016. In 2017, the latest checklist (Buaruang et al. 2017) included 1,297 species, more than double the taxa of the preceding one. This is a high figure when compared to other countries in Southeast Asia, such as the Philippines with 1,262 species (Paguirigan et al. 2020), Singapore with 322 (Sipman 2010, Weerakoon et al. 2015 and Vietnam with 300 taxa (Aptroot & Sparrius 2006, Nguyen et al. 2011, Joshi et al. 2013, 2014. ...

... This decision was based on Malmideaceae being sister to Pilocarpaceae in the analysis by Kalb et al. (2011) and as sister to the Sphaerophorinae in fig. 10 of Spribille et al. (2020). The recently described genus Kalbionora was placed in the Malmideaceae by its authors (Sodamuk et al. 2017) but, in a subsequent analysis using wider taxon sampling and more loci, a placement of Kalbionora within Malmideaceae was not supported (Spribille et al. 2020). Consequently, we excluded Kalbionora from our analyses. ...

... The taxa included here are primarily divided by perispores being either gibbose, verrucose or smooth. A challenge in comparing G. cyanea with related Pannariaceae genera is that two of the latter, Lepidocollema and Physma, are not monophyletic according to recent phylogenies (Magain & Sérusiaux 2014;Elvebakk et al. 2016;Rangsiruji et al. 2016). The approach here was to focus on specimens already included in phylogenies and to name their clades Lepidocollema I and II and Physma I and II. ...

... Distribution: Pantropical. Asia (India, Japan, the Philippines, Sri Lanka, and Thailand), Oceania (Australia and Papua New Guinea), and South America (Brazil, Colombia, Costa Rica, and Guyanas) (Aptroot, 2009;Kashiwadani et al., 2009;Singh and Sinha, 2010;Flakus et al., 2013;Buaruang et al., 2017 Mongkolsuk et al. (2012). ...

... In subsequent years, lichen collecting intensified in several natural areas: at Queen Sirikit Botanic Garden, Chiang Mai Province; Phuteen Suansai forest, Loei Province; at Khao Yai National Park, Nakorn Rachasima, Saraburi, Nakorn Nayok and Prachinburi Province; at Phuhin Rongkla National Park, Phitsanulok province, at Phu Luang Wildlife Sanctuary, Loei Province and other places (Monkolsuk et al. 1996, 1997, Boonpragob et al. 1998, Mongkolsuk & Poengsungnoen. 2012, Poengsungnoen et al. 2014a, 2014b, Sutjaritturakan et al., 2014. This led to a much expanded recent checklist containing 290 species records in 46 genera of Graphidaceae (Buaruang et al. 2017). ...

... Graphidaceae is the largest family of crustose lichens worldwide (Staiger 2002;Frisch 2006;Lücking et al. 2014Lücking et al. , 2017. Research on this family in South Africa has been piecemeal, beginning with the description of Thelotrema henatomma Ach. by Acharius (1804). ...

... Ascomata are unknown in Cheiromycina and Savoronala, which are instead recognised by their prominent sporodochia (Ertz et al. 2013, Muggia et al. 2017. Ascospores with up to 3 septa are known in Crustospathula and Kalbionora, but Crustospathula is also characterised by stalked soralia, Kalbionora by a brown hypothecium, and both genera by a variety of lichen substances not involving fumarprotocetraric acid (Kalb et al. 2012, Sodamuk et al. 2017. All genera except Malmidea currently include 1-4 species, while Malmidea has 52 species (Wijayawardene et al. 2020). ...

... También se requirió de la aplicación de las pruebas químicas convencionales (K, C, P, I) y la exposición a la luz UV (Brodo et al. 2001). Se consultaron claves taxonómicas especializadas para géneros y especies , Amtoft et al. 2008, Mongkolsuk et al. 2015, Brodo et al. 2016, Kitaura et al. 2019. Para Heterodermia se usaron las claves de Mongkolsuk et al. (2015) y de Souza et al. (2022), en conjunto con la diferenciación de los cristales de ácido salazinico y ácido norstictico. ...
