Fungal Genus

The fungal genus Agaricus includes edible, medicinal and some toxic species mainly in the Agaricus sect. Xanthodermatei. As the diversity of the genus is not well known in Iran, an inventory of the species has begun in 2013 in different provinces. Morphological and/or molecular analyses of 12 selected specimens from recent field collections and from herbarium specimens revealed that ten of them belonged to four potentially poisonous species of the Agaricus sect. Xanthodermatei: A. iodosmus, A. moelleri, A. phaeolepidotus and A. xanthodermus. Moreover, our study revealed that previous first records of A. xanthodermus and A. moelleri in Iran had been based on morphologically misidentified and correctly identified specimens, respectively. Finally, three species, A. iodosmus, A. phaeolepidotus and A. xanthodermus are reported as new records for Iran mycobiota. The four species of the section are described and illustrated.

The pantropically distributed Begonia (Begoniaceae) is one of the most species-rich genera. Philippines is one of the diversity centers of Southeast Asian Begonia. In our 2012 field survey, three species of Begonia section Petermannia were collected in Barangay Sagubo, Municipality of Kapangan, Province of Benguet in the northern Luzon Island, Philippines. Our study on literatures and herbarium specimens suggests that these collections consist of B. crispipila, an unknown new species hereby we named B. balangcodiae, and the natural hybrid between them. Molecular analyses confirm that the former contributed the maternal genome while the latter provided the paternal genome. We name the natural hybrid B. × kapangan, which is the first natural hybrid reported in sect. Petermannia.

Insight Into

In order to initiate a taxonomical revision of the Dianthus sylvestris group, an inventory of historical herbarium materials from ZA and ZAHO collections was conducted. Herbarium specimens of D. sylvestris group from these two herbaria were digitized and the data from the original herbarium labels were inserted in the Flora Croatica Database. A total of 344 herbarium sheets were digitized and six taxa (D. sylvestris Wulfen in Jacq. ssp. sylvestris, D. sylvestris ssp. tergestinus (Rchb.) Hayek, D. sylvestris ssp. longicaulis (Ten.) Greuter et Burdet, D. sylvestris ssp. nodosus (Tausch) Hayek, D. siculus C. Presl and D. arrosti C. Presl) were registered within studied collections. Inventory of herbarium sheets from ZA and ZAHO historical collections provided a significant insight into historical distributional data of D. sylvestris taxa related to the area of the Balkan Peninsula, which is a prerequisite for accurate taxonomic/ geographic sampling for further morphological and molecular analyses.

The inventory and assessment of species diversity in the mono-generic family Begoniaceae C. A. Agardh of Bangladesh were made through long term field investigations, collections, identification, survey and examination of preserved herbarium specimens and review of relevant taxonomic and floristic literature. The family is recognized to be represented in the flora of Bangladesh by 19 species under the genus Begonia L. Of these, 11 species were known to be previously recorded from the area of Bangladesh, hence additional 8 species of the present account are being reported here for the first time as new records from Bangladesh, these are: Begonia grandis Dryand. ssp. holostylla Irmsch. , B. heracleifolia Cham. and Schltdl. Cult., B. maculata Raddi Cult. B. modestiflora Kurz, B. muliensis T. T. Yu. Cult., B. scintillans Dunn, B. surculigera Kurz and B. thomsonii A. DC. An enumeration of these 19 species is prepared, and each species is cited with detailed taxonomic data. All species of the Begonia L. are herbaceous in nature and possess potential economic values, viz. 11 (52%) medicinal, 5 (24%) ornamental, 3 (14%) beverage, 1 (5%) food and 1 (5%) poisonous. Determination of status of occurrence showed that 2 (10.53%) species are common, 5 (26.32%) cultivated, 9 (47.36%) threatened and 3 (15.79%) possibly extinct in Bangladesh. Field photographs and hand drawings of recorded taxa are provided.J. Biodivers. Conserv. Bioresour. Manag. 2018, 4(1): 35-46

Background and aims – The intensive botanical prospections carried out in Gabon since the publication of the national checklist in 2006 have resulted in c. 34 300 new specimens (amounting to 30% of all collections made in the country) and an annual increase of 25 species in average. As a result, 5175 species of vascular plants are now recorded from Gabon, of which 650 are considered endemic. However, most of the recent discoveries have not yet been published. This paper is the first of a series documenting additions to the flora of Gabon, and new records of poorly known species. It concerns specifically new records from the Lower Ogooué Ramsar site, the third largest delta of Africa, and certainly the most intact, which includes 80% of the country’s wetlands and a wide variety of other habitats.Methods – The new records presented here come essentially from fieldwork conducted in Gabon between 2008 and 2016 by the authors and colleagues. Further information comes from the study of herbarium specimens in BR, BRLU, K, LBV, MO, P and WAG. For each species, information on distribution and ecology is given, and the studied Gabonese collections listed. In case of rare or range-restricted species, collections from other countries are also listed, and a distribution map is provided, as well as an evaluation of the conservation status based on the categories and criteria of the IUCN Red List.Key results – We report 18 additions to the flora of Gabon, including four genera new to the country (Capparis, Gisekia, Hoffmanniella and Leptochloa) and the first records of the neotropical Justicia secunda being naturalised in tropical Africa. New distribution records are also provided for 16 rare Gabonese endemics or near-endemics. Some species are also newly reported from Cameroon (Cissus leemansii, Salacia coronata) and Equatorial Guinea (Cissus leemansii, C. louisii, Lychnodiscus grandifolius, Placodiscus resendeanus, Rutidea gabonensis, Uvaria bipindensis). Two species, which were reported in the 2006 checklist based on misidentifications, are excluded from the Gabonese flora.

Canary Grass

In cases where invasive species are presumed to be strictly exotic, the discovery that the species is also native can be disconcerting for researchers and land managers responsible for eradicating an exotic invasive. Such is the case with reed canarygrass (Phalaris arundinacea), for which decades of misinformation led to the call for nationwide control of this species in the United States. However, native populations were first reported by LaVoie and then later confirmed by Casler with molecular analyses. This, coupled with the discovery by Anderson that this species has been used in weavings by Native Americans for centuries, also made the native forms of interest for protection. Identifying the native status of historic, herbarium specimens via molecular analyses is of great interest to determine localities of native populations for confirmation with extant specimens. Genetic-based methods describing DNA polymorphism of reed canary grass are not well developed. The goal of the presented research is to assess the utility of genomic DNA obtained from historic (herbaria) and extant (fresh) tissue of reed canarygrass and the application of using Diversity Arrays Technology sequencing low density for genetic population studies.

Glandonia is a rare genus comprising three species confined to Amazonian rainforest. Glandonia macrocarpa has been documented in some localities of the lower Rio Negro, in the municipality of Manaus, Brazil. Glandonia prancei is represented by only a few herbarium specimens, which were collected along the Madeira and Purus rivers in the 1960s and 70s. A recent record of G. prancei was discovered while analyzing collections of G. macrocarpa, providing a new locality where we found and collected G. prancei. Glandonia williamsii, which had not been recorded in Brazil for the past three decades, was collected in the upper Rio Negro in this study. This work reexamines the taxonomy of the genus, based on fieldwork and herbarium specimens, and includes notes on morpho-anatomy, distribution and phenology. New morpho-anatomical characters are provided to better describe the species (e.g., outline of epidermal cell walls of the leaf, arrangement of petiolar vascular system, bracteole gland surface, and distribution of glands on the leaf blade and petals).

Four new species of the genus Atopsyche Banks (Hydrobiosidae) from Pantepui biogeographical region (Venezuela) are described and illustrated: Atopsyche (Atopsaura) inmae n. sp., Atopsyche (Atopsaura) cristinae n. sp., Atopsyche (Atopsaura) svitoki n. sp., and Atopsyche (Atopsaura) carmenae n. sp. Molecular analyses (cox1 sequences) allowed larva-adult associations and the morphological description of larvae of two of the new species (A. inmae and A. cristinae). A phylogenetic tree is performed to assess the molecular validity of the species, establish evolutionary relation among them and interpret historical biogeography of tepuis. Finally, two new distributional records for A. (Atopsaura) atahuallpa are included, which up to now was known only from the type locality.

AbstractUsing flow cytometry in fresh plants and herbarium vouchers, DNA ploidy levels for 411 individuals of 44 taxa of the genus Festuca, including 4 natural hybrids, originating from 237 sites in Austria, Bulgaria, Croatia, Czech Republic, Estonia, Germany, Hungary, Italy, Poland, Romania, Slovakia, Slovenia, and Switzerland were estimated. The following taxa and DNA ploidy levels are reported: F. airoides (2n ≈ 2x), F. alpestris (2n ≈ 2x), F. alpina s.l. (2n ≈ 2x), F. amethystina subsp. amethystina (2n ≈ 4x), F. bosniaca subsp. bosniaca (2n ≈ 2x), F. brevipila (2n ≈ 6x), F. bucegiensis (2n ≈ 2x), F. carnuntina (2n ≈ 6x), F. csikhegyensis (2n ≈ 4x), F. csikhegyensis × F. eggleri (2n ≈ 4x), F. dalmatica (2n ≈ 4x), F. duvalii (2n ≈ 4x), F. eggleri (2n ≈ 2x, 4x), F. filiformis (2n ≈ 2x), F. glauca (2n ≈ 6x), F. heterophylla (2n ≈ 4x), F. inops (2n ≈ 2x), F. laevigata (2n ≈ 8x), F. laxa (2n ≈ 4x), F. lemanii (2n ≈ 6x), F. norica (2n ≈ 2x), F. ovina subsp. ovina (2n ≈ 2x), F. ovina subsp. guesfalica (2n ≈ 4x), F. ovina × F. pallens (2n ≈ 4x), F. pallens (2n ≈ 2x, 3x), F. pallens × F. pseudodalmatica (2n ≈ 3x, 4x), F. pirinica (2n ≈ 2x), F. polesica (2n ≈ 2x), F. psammophila subsp. dominii (2n ≈ 2x), F. pseudodalmatica (2n ≈ 4x), F. pseudovina (2n ≈ 2x), F. quadriflora (2n ≈ 4x), F. rupicola (2n ≈ 6x), F. rupicola × F. vaginata (2n ≈ 3x, 4x), F. saxatilis (2n ≈ 6x), F. stricta subsp. bauzanina (2n ≈ 8x), F. supina (2n ≈ 4x), F. tatrae (2n ≈ 2x), F. valesiaca (2n ≈ 2x), F. versicolor subsp. pallidula (2n ≈ 2x), F. versicolor subsp. versicolor (2n ≈ 2x), F. violacea subsp. puccinellii (2n ≈ 2x), F. wagneri (2n ≈ 4x), F. xanthina (2n ≈ 2x). In F. pallens, up to 12-year-old herbarium specimens were proved to be suitable for DNA ploidy level measurements with flow cytometry.DNA ploidy levels of F. bucegiensis, F. bosniaca, and F. versicolor subsp. pallidula are reported here for the first time. The taxonomy of some polyploid complexes and several records of mixed ploidy level populations are briefly discussed. Festuca pseudodalmatica and its hybrid F. × krizoviensis were first recognised as native to the Czech Republic, and F. brevipila as native to Hungary. Also some new records of F. filiformis, F. brevipila, and F. wagneri from Slovakia are reported.
