“…Anatomical measurements were made from 15–20 apothecial sections, and the lower and higher values show the minimum and maximum of the range. Various publications (Staiger 2002; Nakanishi et al 2003; Kalb et al 2004; Archer 2006, 2009; Qing-Feng & Jiang-Chun 2008; Makhija et al 2009; Sharma & Makhija 2009 a , b ; Sharma & Khadilkar 2011, 2012) were consulted for species identifications. Images were taken using ZEISS Scope A1 (AX10) and Axio cam ERc 5s, and illustrations were prepared using Coral Draw (version 12).…”

“…Kalb et al , D. pruinosum (Eschw.) Kalb et al , D. rufopruinosum (A. W. Archer) Kalb et al , D. reniforme (Fee) Kalb et al and D. agumbense B. O. Sharma & Khadilkar (Kalb et al 2004; Sharma & Khadilkar 2012). The new taxon closely resembles D. pruinosum , which has a greenish white, smooth, dull thallus, conspicuous, immersed, white, irregular apothecia, a densely pruinose disc, 150–200 µm high hymenium, 1-spored asci and multicelled, muriform ascospores, but it can be distinguished by an open and ±convex apothecial disc, laterally and basally carbonized proper exciple, and smaller ascospores, 100–150 (–175)×20–30 µm (Kalb et al 2004).…”

Acanthothecis salazinica and Diorygma archeri are described from Vietnam. The former is characterized by having a leprose thallus, creamish to whitish, entire, epruinose labia, a slit-like disc, a hyaline to brown, entire proper exciple, warty periphysoids, 8-spored asci, and 28–30-loculate, hyaline, I− ascospores, 70–120×7–14 µm in size. The latter has a greenish grey thallus, a poorly developed, hyaline to pale or brownish proper exciple, 1-spored asci, hyaline, muriform ascospores, and produces protocetraric acid. Acanthothecis corcovadensis, Diorygma erythrellum, D. junghuhnii, D. macgregorii, Platygramme platyloma, Pliariona montagnei and Thecaria quassiicola are recorded for the first time from the country.

“…Several new taxa discovered in this material are formally introduced here, focusing on the genus Diorygma. The high number of new Diorygma species seems astonishing, especially after the world-monograph by Kalb et al (2004) and the subsequent additions to this genus by Indian lichenologists (Sharma & Makhia 2009a, b;Makhia et al 2009;Sharma & Khadilkar, 2012). Within a few years, 16 new species were described in these papers…”

New species of Graphidaceae (Ostropales, Lecanoromycetes) from southern Thailand

et al. 2014

View full text Add to dashboard Cite

Fourteen species of the lichen family Graphidaceae from southern Thailand are described as new, namely Creographa subbrasiliensis, which is similar to C. brasiliensis but without chemistry; Diorygma angusticarpum, which differs from D. hieroglyphicum by a I+ blue hymenium and lirellae with a slit-like disc; D. chumphonense, distinguished by its small, densely muriform ascospores and production of salazinic and norstictic acids; D. citri, distinguished by a I- hymenium and a complex chemistry including salazinic and hypostictic acids as major metabolites; D. conprotocetraricum, which is unique by its chemistry, i.e. conprotocetraric acid as a major substance; D. fuscopruinosum with a brown pruina on the disc of the apothecium and comparatively small ascospores; D. hieroglyphicellum, which is similar to D. hieroglyphicum but differs by much smaller ascospores; D. inexpectatum, which is distinguished by its chemistry (salazinic and hypostictic acids) and a I+ blue hymenium; D. salazinicum, separated from D. pruinosum by its rare chemistry (stictic and salazinic acids as ± major metabolites); D. subpruinosum, distinguished by often 2-spored asci and protocetraric and hypostictic acids as major constituents; D. thailandicum, which is similar to D. pruinosum, but differs by protocetraric and stictic acid as major metabolites; Graphis australosiamensis, distinguished by one muriform ascospore per ascus, a laterally carbonized exciple and norstictic acid in the thallus; Ocellularia palianensis, distinguished by small, transversely septate ascospores and by producing two unknown substances; and Platygramme microspora, which is distinguished by very small transseptate ascospores and producing stictic acid and its satellites.

“…So far c . 50 species are known in the genus, half of which were treated in a preliminary monograph (Kalb et al 2004), the other half in subsequent papers (Cáceres 2007; Archer 2009; Makhija et al 2009; Sharma & Makhija 2009 a , b ; Lumbsch et al 2011; Sharma & Khadilkar 2012; Lima et al 2013).…”

Three new corticolous Diorygma species are described from Brazil. Diorygma incantatum has transversely 29–31-septate, filiform ascospores 105–108×6 µm, and produces an unidentified substance with Rf 44 in solvent C. Diorygma pauciseptatum produces norstictic and connorstictic acids and has transversely 7–9-septate, I+ blue-violet, large ascospores 28–32×7 µm, surrounded by a gelatinous sheath c. 2 µm wide that is often somewhat expanded at one end. Diorygma tocantinense contains protocetraric acid and has muriform, broadly fusiform ascospores with rounded ends, 24–40×10–15 µm, surrounded by an gelatinous sheath up to c. 5 µm wide that is somewhat expanded at central parts of the ascospore. A revised world key is given to all currently known species of Diorygma.
