Contributions to Molecular Phylogeny of Lichen-Forming Fungi 2. Review of Current Monophyletic Branches of the Family Physciaceae

Seven genera new to science, i.e.: Helmutiopsis, Huriopsis, Johnsheardia, Klauskalbia, Kudratovia, Kurokawia and Poeltonia of the Physciaceae are proposed for the ‘Rinodina’ atrocinerea, the ‘Rinodina’ xanthophaea, the ‘Rinodina’ cinnamomea, the ‘Heterodermia’ obscurata, the ‘Rinodina’ straussii, the ‘Anaptychia’ isidiata and the ‘Physconia’ grisea groups consequently that all form strongly supported monophyletic branches in a phylogeny analysis based on a combined matrix of nrITS and mtSSU sequences. Phylogenetic positions of species belonging to the genera Kashiwadia s. l., Leucodermia, Mischoblastia,Oxnerella, Phaeorrhiza s. l., Polyblastidium and Rinodinella s. l. are discussed. Oxnerella afghanica which for the first time recorded as parasitic lichen species from both epiphytic and saxicolous crustose lichens is designated as type species for the genus Oxnerella. Sequences of the recently described Physcia orientostellaris as well as Huriopsis xanthophaea and additional sequences of Kashiwadia aff. orientalis and Mischoblastia aff. oxydata are submitted to the GenBank. The positions of Polyblastidium casaterrinum from Costa Rica, ‘Rinodina’ efflorescens from Białowieża, Poland, and ‘Mischoblastia’ confragosula from Cambodia in the Physciaceae are confirmed in a phylogeny analysis based on the nrITS sequences. The presence of ‘extraneous mycobiont DNA’ in lichen associations is exemplified with earlier incorrect identifications of Heterodermia, Kashiwadia, Kurokawia,Oxnerella and Poeltonia specimens. Fifty-six new combinations are presented: Helmutiopsis alba (for Rinodina alba Metzler ex Arn.), Helmutiopsis aspersa (for Lecanora aspersa Borrer), Helmutiopsis atrocinerea (for Parmelia atrocinerea Fr.), Huriopsis chrysidiata (for Rinodina chrysidiata Sheard), Huriopsis chrysomelaena (for Rinodina chrysomelaena Tuck.), Huriopsis lepida (for Lecanora lepida Nyl.), Huriopsis luteonigra (for Rinodina luteonigra Zahlbr.), Huriopsis plana (for Rinodina plana H.

Two new species and new records of lichen-feeding darkling beetles (Coleoptera: Tenebrionidae: Helopini) from Turkey with notes on bionomics and trophic relations

Turkonalassus mavi M. Nabozhenko & B. Keskin, sp. n. and Odocnemis rufocruralis M. Nabozhenko & B. Keskin, sp. n., two distinctive darkling beetle species of the tribe Helopini, are described from the Southeastern Anatolia region of Turkey, based on both their external morphology and genital structures. Turkonalassus mavi sp. n. differs from all congeners by the bluish dorsal surface of the body, the pronotum widest before middle, and wide merged baculi of the median lobe of the aedeagus. Odocnemis rufocruralis sp. n. belongs to the praelonga species-group. Odocnemis rufocruralis sp. n. is similar to O. torosica Nabozhenko & Keskin, 2016, O. terminassianae (Nabozhenko, 2011) and O. kakunini Nabozhenko & Keskin, 2016 but differs from all three taxa by the reddish-brown body with red legs, male apical maxillary palpomere wider than in female, elevate and narrowly separate male protrochanters, and the structure of the very long and narrow apical piece of the aedeagus. New data on distribution, bionomics, and trophic relations of several species of Helopini from Turkey are given. Host lichens are determined for nine species. The majority of studied adult beetles feed on lichens from the families Physciaceae and Parmeliaceae. Some examined taxa feed on Cladoniaceae. Feeding on crustose lichens is registered for the first time for Coleoptera, specifically Odocnemis rufocruralis sp. n. was observed to feed on Pertusaria sp. (on Prunus) in Mardin Province.

Bactrospora totonacae (Arthoniales, Ascomycota), a new species from Veracruz, Mexico

Background and Aims: Bactrospora is a genus of crustose lichens characterized by its black, verrucose to denticulate and little apothecia, and mostly acicular, or sometimes muriform spores, longer than wide. The genus is represented by 38 accepted species. The aim of this work is to describe Bactrospora totonacae, a new species from the tropical dry forest of Veracruz, Mexico. Methods: The specimens were collected on the “Cerro de los Metates” in the municipality of Actopan, Veracruz, Mexico. Macrochemical tests, UV reaction, and a thin layer chromatography were performed; likewise, the presence of amyloid substances distributed in the thallus and ascomata was verified with Lugol’s solution. The voucher is deposited in the herbarium XALU of the Facultad de Biología of the Universidad Veracruzana. Key results: The new species Bactrospora totonacae is characterized by the pruine K+ reddish magenta in its disc. Conclusions: The described species is unique in Bactrospora because the combination of pruine K+ reddish magenta and a thick carbonized exciple has never been reported in this genus.

Lichen as bioindicator of air quality at buffer zone of Banjarbaru town

Air pollution is one of the main issues faced by urban areas. Therefore, morphological characteristic and colony coverage of lichen growing at different scale air-polluted area could become as a bioindicator of their air quality. This research aims to determine the condition of lichen in spots located at near and far from the main road (width ± 29 meter) in urban area at Banjarbaru town. This research used descriptive method with purposive sampling technique. Sample were obtained from 2 plots those were far and near the main road, each plot represented by samples from 5 different trees (densed canopy with minimum DBH at 25 cm). Lichens were taken at 50-150 cm above ground level using 20x20 cm quadrant plastic frame. Observation variables include the number and shape of colonies, color and type of thallus, and percentage of thallus cover. We determined 13 colonies from spots far from the main road (500-600 meter from main road). Lichen dominated by green to bluish color, thallus consist of crustose and foliose, and the average percentage of thallus cover was 28.01%. While from that near the main road (14-250 meter from main road), we determined 14 colonies predominantly consisted of white crustose lichens, and the average percentage of thallus cover was 10.01%. Traffic intensity showed to have significant effect on lichens community. The main difference can be seen from morphology and colony coverage. Based on this result, lichen can be used as bioindicator of air quality, especially air pollution caused by motorized vehicles. Keywords arboretum, crustose, foliose, pollution, thallus

Stand-Level Variation Drives Canopy Water Storage by Non-vascular Epiphytes Across a Temperate-Boreal Ecotone

Epiphytes, including bryophytes and lichens, can significantly change the water interception and storage capacities of forest canopies. However, despite some understanding of this role, empirical evaluations of canopy and bole community water storage capacity by epiphytes are still quite limited. Epiphyte communities are shaped by both microclimate and host plant identity, and so the canopy and bole community storage capacity might also be expected to vary across similar spatial scales. We estimated canopy and bole community cover and biomass of bryophytes and lichens from ground-based surveys across a temperate-boreal ecotone in continental North America (Minnesota). Multiple forest types were studied at each site, to separate stand level and latitudinal effects. Biomass was converted into potential canopy and bole community storage on the basis of water-holding capacity measurements of dominant taxa. Bole biomass and potential water storage was a much larger contributor than outer canopy. Biomass and water storage capacity varied greatly, ranging from 9 to >900kg ha–1 and 0.003 to 0.38 mm, respectively. These values are lower than most reported results for temperate forests, which have emphasized coastal and old-growth forests. Variation was greatest within sites and appeared to reflect the strong effects of host tree identity on epiphyte communities, with conifer-dominated plots hosting more lichen-dominated epiphyte communities with lower potential water storage capacity. These results point to the challenges of estimating and incorporating epiphyte contributions to canopy hydrology from stand metrics. Further work is also needed to improve estimates of canopy epiphytes, including crustose lichens.

Two new species of Astrothelium (Trypetheliaceae) with amyloid ascospores inhabiting the canopy of Quercus humboldtii trees in Colombia

Subandine and high Andean forests are often dominated by oak trees and these are recognized as suitable phorophytes for diverse epiphyte communities. Among the latter, lichens in the upper strata appear to be understudied. Here, we report the discovery of two new species of Astrothelium (Trypetheliaceae), a diverse genus of tropical crustose lichens, both with the unusual feature of muriform, amyloid ascospores. Astrothelium mordonialensis is characterized by an olive-green thallus with solitary ascomata producing muriform and amyloid ascospores with tightened center and A. rogitamae by a light brownish to greenish grey thallus with yellow pigmented solitary ascomata, producing muriform and amyloid ascospores.

Addition of 96 lichen species to the state of Odisha from Similipal Biosphere Reserve

A total of 96 species of lichens taxa belonging to 45 genera and 20 families are enumerated from Similipal Biosphere Reserve, in Mayurbhanj district as an addition to the lichen biota of Odisha, India. Most of the crustose lichen taxa usually growing as epiphytes on different phorophytes of the biosphere reserve exhibit their dominance. Among crustose lichens the members of family Graphidaceae with 26 species of 14 genera shown their maximum dominance. Together with Graphidaceae the lichen genus Pyrenula represented by 15 species found growing luxuriantly on smooth barked trees of the biosphere reserve. The dominant trees in the biosphere such as Shorea robusta Gaertn. followed by Mangifera indica L., Simarouba glauca DC. and Madhuca longifolia (L.) J. F. Macbr., provided suitable habitat for a number of lichen taxa to colonize. The south-west (SW) region of Similipal Biosphere Reserve exhibits the maximum additions of lichens, followed by north-west (NW), north-east (NE) and south-east (SE) respectively.

Host plant specificity of corticolous lichens in urban and suburban New Amsterdam, Berbice, Guyana

In this study, host plant - lichen specificity was investigated. Data was collected from 1000m2 sampling plots at each of four locations with an established 50m x 20m plot at each site. Forty-one trees from across five species were examined using (10cm by 50cm) ladder quadrats on tree trunks (N, S, E, W) at 150cm height. A total of 14978 individual lichens were identified that yielded 10 families, 13 genera and 18 species. Swietenia mahagoni showed the highest average corticolous lichen species composition, followed by Terminalia catappa and Melicoccus bijugales respectively. Cocos nucifera had a higher average species recorded than Mangifera indica. Crustose lichens were the most prominent corticolous lichens observed (61%) with the most individuals in Graphidaceae and Arthoniaceae. Foliose lichens (28%) showed the most abundance in Parmeliaceae, Caliciaceae and Collemataceae. Of the taxa recorded, 22.2% were restricted to specific trees. C. parasitica, H. laevigata, U. cornuta were restricted to S. mahagoni. D. applanata was restricted to C. nucifera. 22.2% of recorded species were found on all of the tree hosts that were examined. Bacidia laurocerasi, Flavoparmelia caperata, Flavoparmelia soredians and Graphina anguina. S. mahagoni hosted 88.9% of all recorded species. Swietenia mahagoni showed the highest average of recorded corticolous lichen species of all host trees with 7.58. Mangifera indica showed the lowest average with 4. The maximum number of species (10) was recorded on one S. mahagoni tree
