New lichen species from Thailand, new combinations and new additions to the Thai lichen biota
(2017-12-19)

Several collecting trips by the authors (alone or together) over the last ten years in twenty-one provinces of Thailand afforded new additions to the most recent Thai lichen checklist. These are from seven families with an emphasis on the Graphidaceae reflecting the current interest of the authors. Two species are described as new to science: Platygramme subcolubrosa which differs from P. colubrosa in having non-pruinose labia and discs and smaller, less-septate ascospores and Ramonia minima, which differs from R. kandleri in having smaller ascomata, a lower hymenium and a partly brown to blackish exciple. Constrictolumina leucostoma is a new finding for the Palaeotropics and the genera Pseudotopeliopsis, Ramonia and Sclerophyton are new reports for Thailand. New records of Thai species of Hemithecium are transferred to Allographa and Graphis. This necessitated the following new combinations: Allographa stictilabiata (≡ Graphina stictilabiata), Graphis aphaneomicrospora (≡ Hemithecium aphaneomicrosporum), G. balaghatensis (≡ Hemithecium balaghatense) and Graphis indica (a new name for Hemithecium norsticticum). A further new combination includes Traponora varians (≡ Lecidea varians). Acanthothecis consocians, Caloplaca bassiae, Chapsa pulchra, Leucodecton occultum, Phaeographopsis palaeotropica, Platygramme australiensis, P. commutabilis, P. discurrens, Sclerophyton seriale, Psudotopeliopsis longisporum, Traponora macrospora and Trinathotrema stictideum are further new additions to the Thai lichen biota. Working keys are presented to all known species of Phaeographopsis and Trinathotrema and to the Thai species of Platygramme.

A new revised checklist of lichenized fungi in Thailand is presented, including 1,292 species. Recent work on the taxonomy of these organisms in Thailand resulted in an enormous increase in our knowledge of the lichen biota of the country - the current checklist includes more than twice as many species as the previous catalogue published 15 years ago - and phylogenetic studies resulted in numerous changes in the generic classification of lichenized fungi. Hence, a new checklist is here presented summarizing the current knowledge of lichens in Thailand. Six new records are reported, viz. Acanthothecis salazinica, Bactrospora metabola, Buellia parastata, Diploschistes cinereocaesius, Rolfidium coccocarpioides, and Trapelia placodioides. Five previously recorded species, namely Lecanora carpinea, Platismatia glauca, P. lacunosa, P. tuckermanii and Roccella phycopsis are shown to be based on misidentifications and are excluded from the checklist. Three new combinations of species previously placed in Pertusaria to Lepra are proposed: L. bulolensis (A.W.Archer, Elix & Streimann) Schmitt & Lumbsch, L. patellifera (A.W.Archer) Schmitt & Lumbsch, and L. subventosa (Malme) Schmitt & Lumbsch.

New Coenogonium species (Ostropales: Coenogoniaceae) from Thailand, new reports and a revised key to the species occurring in the country

A revision of 159 Coenogonium collections from Thailand preserved in RAMK, herb. K. Kalb and herb. K. & J. Kalb is presented. 18 species (including 1 doubtful) could be delimited, three of which are described as new to science, namely C. convexum which differs from the similar C. nepalense by smaller and convex apothecia already at a very early stage of development, C. subborinquense which has larger apothecia (almost double the size) than the similar C. borinquense and C. verrucimarginatum which differs from C. coronatum by having denticulate-verrucose margins of the apothecia. Coenogonium barbatum, C. epiphyllum, C. frederici, C. leprieurii and C. queenslandicum are new additions to the Thai lichen biota. C. disciforme is synonymized with C. isidiiferum. The peculiar vegetative propagules in this species, hitherto named isidia, are described as thallodiscs. Photographs showing the habitus of the species as well as characteristic structures are given and a dichotomous key for the identification of all species is provided.

The number of undescribed species of lichenized fungi has been estimated at roughly 10,000. Describing and cataloging these would take the existing number of taxonomists several decades; however, the support for taxonomy is in decline worldwide. In this paper we emphasize the dire need for taxonomic expertise in lichenology. We bring together 103 colleagues from institutions worldwide to describe a total of 100 new species of lichenized fungi, representing a wide taxonomic and geographic range. The newly described species are: Acarospora flavisparsa, A. janae, Aderkomyces thailandicus, Amandinea maritima, Ampliotrema cocosense, Anomomorpha lecanorina, A. tuberculata, Aspicilia mansourii, Bacidina sorediata, Badimia multiseptata, B. vezdana, Biatora epirotica, Buellia sulphurica, Bunodophoron pinnatum, Byssoloma spinulosum, Calopadia cinereopruinosa, C. editae, Caloplaca brownlieae, C. decipioides, C. digitaurea, C. magnussoniana, C. mereschkowskiana, C. yorkensis, Calvitimela uniseptata, Chapsa microspora, C. psoromica, C. rubropulveracea, C. thallotrema, Chiodecton pustuliferum, Cladonia mongkolsukii, Clypeopyrenis porinoides, Coccocarpia delicatula, Coenogonium flammeum, Cresponea ancistrosporelloides, Crocynia microphyllina, Dictyonema hernandezii, D. hirsutum, Diorygma microsporum, D. sticticum, Echinoplaca pernambucensis, E. schizidiifera, Eremithallus marusae, Everniastrum constictovexans, Fellhanera borbonica, Fibrillithecis sprucei, Fissurina astroisidiata, F. nigrolabiata, F. subcomparimuralis, Graphis caribica, G. cerradensis, G. itatiaiensis, G. marusa, Gyalideopsis chicaque, Gyrotrema papillatum, Harpidium gavilaniae, Hypogymnia amplexa, Hypotrachyna guatemalensis, H. indica, H. lueckingii, H. paracitrella, H. paraphyscioides, H. parasinuosa, Icmadophila eucalypti, Krogia microphylla, Lecanora mugambii, L. printzenii, L. xanthoplumosella, Lecidea lygommella, Lecidella greenii, Lempholemma corticola, Lepraria sekikaica, Lobariella sipmanii, Megalospora austropacifica, M. galapagoensis, Menegazzia endocrocea, Myriotrema endoflavescens, Ocellularia albobullata, O. vizcayensis, Ochrolechia insularis, Opegrapha viridipruinosa, Pannaria phyllidiata, Parmelia asiatica, Pertusaria conspersa, Phlyctis psoromica, Placopsis imshaugii, Platismatia wheeleri, Porina huainamdungensis, Ramalina hyrcana, R. stoffersii, Relicina colombiana, Rhizocarpon diploschistidina, Sticta venosa, Sagenidiopsis isidiata, Tapellaria albomarginata, Thelotrema fijiense, Tricharia nigriuncinata, Usnea galapagona, U. pallidocarpa, Verrucaria rhizicola, and Xanthomendoza rosmarieae.
