“…Otherwise, this species fits well in the genus Chapsa sensu Rivas Plata et al (2010) and, in the subdivision of Chapsa by Parnmen et al (2012), as Astrochapsa. The species is probably best accommodated in the genus Astrochapsa in view of its similarity to A. meridensis.…”

“…The recent progress in the classification of tropical Graphidaceae, and in particular the publication of new identification keys (Lücking et al , 2009Rivas Plata et al 2010;Sipman et al 2012) allowed a new attempt to classify this material. As a result, many could be identified and it became clear that some others represent undescribed species, sometimes even difficult to accommodate in the current generic system.…”

Descriptions and illustrations are provided for 20 new species in the family Graphidaceae (lichenized fungi) originating from El Salvador, the Guianas, Venezuela, Colombia, and Malaysia: Acanthothecis adjuncta Welz & Sipman, differing from all other Acanthothecis species by the rounded ascocarps with covered discs; Astrochapsa albella Sipman, differing from A. meridensis in the white apothecium rim, the corticolous growth habit, the more or less clear hymenium, and the protocetraric acid chemistry; A. columnaris Sipman, differing from other Astrochapsa species by the columnar marginal slips; Chapsa francisci Sipman, differing from other Chapsa species by the numerous marginal lacinae; C. nubila Sipman, differing from other Chapsa species by the combination of a guttulate hymenium and 4-to 8-spored asci; Diorygma extensum Sipman, differing from D. minisporum in producing norstictic acid instead of stictic acid; Fissurina chapsoides Sipman, a Fissurina species with large, muriform ascospores and short ascocarps opening mostly by branched slits; F. gigas Sipman, differing from F. rufula in the larger ascomata and muriform ascospores; F. vorax Sipman, differing from other Fissurina species by the aggregated ascocarps in combination with papillose paraphysis tips; Graphis murali-elegans Sipman, differing from G. elegans and G. lumbricina in the muriform ascospores; G. nigroglobosa Sipman, differing from G. mexicana in the absence of a complete thalline margin; Melanotrema comosum Sipman, a species of Melanotrema with extruding, clavate, brown hyphae on columella and excipulum; Myriochapsa annulata Sipman, differing from M. psoromica by the conspicuous, free excipulum; M. chocoensis Sipman, differing from M. psoromica in the smaller ascospores; Ocellularia pitalensis Sipman, differing from O. maxima by producing hypoprotocetraric acid; O. rugosa Sipman, similar to O. zamorana but with wider ostioles and 1-septate, pigmented ascospores with thick-walled juvenile stage; Thelotrema berendsohnii Sipman, similar to T. alboolivaceum, from which it differs by submuriform ascospores; T. kinabaluense Sipman, differing from other Thelotrema species by small, brown ascospores and protocetraric acid; T. paludosum Sipman, differing from other Thelotrema species by an inspersed hymenium, hypoprotocetraric acid and colorless, transversely septate ascospores of c. 30 × 7 µm; and T. parvisporum Sipman, differing from T. adjectum in the small, grey-brown ascospores.

“…Chemical constituents were identified by thin-layer chromatography using methods standardized for lichen products (Culberson & Kristinsson 1970, Culberson 1972, White & James 1985 with the solvent systems benzenedioxane-acetic acid (180:45:5), hexane-ethyl ether-formic acid (130:80:20), and tolueneethyl acetate-formic acid (139:83:8). Specimens were identified using literature (Nylander 1963, Divakar and Upreti 2005, Lücking et al 2009, Rivas Plata et al 2010) and by comparison with types and protologues. All examined specimens are deposited in Ajrekar Mycological Herbarium (AMH).…”

“…Acanthotrema is a small genus of four species characterized by a corticate thallus, chroodiscoid ascomata, and thin-walled ascospores of the Chroodiscus type (Rivas Plata et al 2010b). This genus, which is found on shaded tree trunks in the lowland rain forest, appears rather isolated within the family on a very long branch and its exact position remains unresolved.…”

We present a comprehensive molecular phylogeny of the lichen family Graphidaceae (subfamilies Graphidoideae and Fissurinoideae) based on partial sequences of the mtSSU, nuLSU rDNA, and RPB2 loci. The phylogeny includes all currently available sequences in Genbank plus 897 newly generated sequences, from a total of 908 ingroup OTUs representing 428 species. The phylogeny supports the synomymy of Graphidaceae and Thelotremataceae and confirms that rounded and lirellate ascomata evolved multiple times in unrelated clades within the family. The phylogenetic distinctiveness of Fissurinoideae versus ReseARCh ARtiCLeEimy Rivas Plata et al. / MycoKeys 6: 55-94 (2013) 56 Graphidoideae is also supported in our extended taxon sampling. The three-gene phylogeny suggest that in addition to the three tribes previously established for the major clades within subfamily Graphidoideae, several further clades exist that might represent additional tribes. Specifically, the Leptotrema clade is excluded from tribe Ocellularieae and the Carbacanthographis, Heiomasia, Topeliopsis, and Wirthiotrema clades are excluded from tribe Thelotremateae. The phylogenetic position of these clades remains unresolved but they are not supported as belonging to these larger tribes. Based on the results, the current status and problems are discussed for all clades and genera currently accepted within the family.
