Isotopic signatures and trophic status of Ramaria
Mycological Progress, 2012Co-Authors: Reinhard Agerer, Josef Christan, Christoph Mayr, Erik HobbieAbstract:The genus Ramaria is composed of several subgenera that often correspond to specific trophic strategies. Because carbon and nitrogen isotopes can be used to assess fungal trophic status and nitrogen sources, we accordingly carried out an extensive survey of isotopic patterns in archived specimens of Ramaria from Germany and other locations. Isotopic patterns in species generally corresponded to subgeneric affiliations and to the range of different potential substrates, with fungi fruiting on wood and litter (subgenera AsteroRamaria and LentoRamaria ) much lower in δ^15N (≈−3‰) than ectomycorrhizal taxa (≈12‰) (subgenus Ramaria ) or taxa fruiting on soil (≈13‰) (subgenus EchinoRamaria ). Conversely, fungi fruiting on wood and litter were higher in δ^13C (−23‰) than those fruiting on soil (≈−27‰), with ectomycorrhizal fungi intermediate (≈−24.5‰). Fungi colonizing mineral soil horizons were about 3‰ enriched in ^15N relative to those colonizing both mineral and organic horizons. The high δ^15N and low δ^13C signatures of taxa fruiting on soil remains unexplained. The high degree of fidelity of isotopic signatures with subgeneric classifications and life history traits suggests that sporocarps are good integrators of patterns of carbon and nitrogen cycling for specific taxa. Archived specimens represent a useful trove of life history information that could be mined without requiring extensive supporting isotopic data from other ecosystem pools.

Ramaria chocoënsis sp. nov., a gomphoid member of Ramaria sect. Dendrocladium from Colombia, El Chocó, with special regards to rhizomorph anatomy
Mycological Progress, 2002Co-Authors: Christoph Hahn, Josef ChristanAbstract:The new species Ramaria chocoënsis (Gomphales, Basidiomycota) from Colombian Pacific rainforest is described. Despite the gomphoid habit, the new species is inserted in Ramaria sect. Dendrocladium due to rhizomorph anatomy. In rhizomorphs of members of Ramaria sect. Dendrocladium , as in the new species R. chocoënsis , peculiar, thick-walled, gnarled, sphere-bearing hyphae are found, a feature unknown for any other higher fungi. A short survey of hitherto known rhizomorph features within the Gomphales is given. The possibility of putting the members of Ramaria sect. Dendrocladium in a separate genus is taken into account. It would be advisable to have additional data by screening the anatomy of the rhizomorphs in other species, to more accurately predict the classification of Ramaria chocoënsis sp. nov.

phylogenetic relationships of the gomphales based on nuc 25s rdna mit 12s rdna and mit atp6 dna combined sequences
Fungal Biology, 2010Co-Authors: Admir J Giachini, Kentaro Hosaka, Eduardo Nouhra, Joseph W Spatafora, James M TrappeAbstract:Abstract Phylogenetic relationships among Geastrales, Gomphales, Hysterangiales, and Phallales were estimated via combined sequences: nuclear large subunit ribosomal DNA (nuc-25S-rDNA), mitochondrial small subunit ribosomal DNA (mit-12S-rDNA), and mitochondrial atp 6 DNA (mit- atp 6-DNA). Eighty-one taxa comprising 19 genera and 58 species were investigated, including members of the Clathraceae, Gautieriaceae, Geastraceae, Gomphaceae, Hysterangiaceae, Phallaceae, Protophallaceae, and Sphaerobolaceae. Although some nodes deep in the tree could not be fully resolved, some well-supported lineages were recovered, and the interrelationships among Gloeocantharellus , Gomphus , Phaeoclavulina , and Turbinellus , and the placement of Ramaria are better understood. Both Gomphus sensu lato and Ramaria sensu lato comprise paraphyletic lineages within the Gomphaceae. Relationships of the subgenera of Ramaria sensu lato to each other and to other members of the Gomphales were clarified. Within Gomphus sensu lato , Gomphus sensu stricto , Turbinellus , Gloeocantharellus and Phaeoclavulina are separated by the presence/absence of clamp connections, spore ornamentation (echinulate, verrucose, subreticulate or reticulate), and basidiomal morphology (fan-shaped, funnel-shaped or ramarioid). Gautieria , a sequestrate genus in the Gautieriaceae, was recovered as monophyletic and nested with members of Ramaria subgenus Ramaria . This agrees with previous observations of traits shared by these two ectomycorrhizal taxa, such as the presence of fungal mats in the soil. Clavariadelphus was recovered as a sister group to Beenakia , Kavinia , and Lentaria . The results reaffirm relationships between the Geastrales, Gomphales, Hysterangiales, and the Phallales, suggesting extensive convergence in basidiomal morphology among members of these groups. A more extensive sampling that focuses on other loci (protein-coding genes have been shown to be phylogenetically informative) may be useful to answer questions about evolutionary relationships among these fungal groups.

antioxidant and antigenotoxic potential of Ramaria largentii marr d e stuntz a wild edible mushroom collected from northeast romania
Food and Chemical Toxicology, 2017Co-Authors: Ana Clara Aprotosoaie, Daniela Zavastin, Cosmin Teodor Mihai, Gabriela Voichita, Daniela Gherghel, Mihaela Silion, Adriana Trifan, Anca MironAbstract:Abstract Ramaria largentii Marr & D. E. Stuntz (orange coral mushroom) is a wild edible mushroom whose chemical composition and bioactivity have not been investigated. Herein, we present a study on the phenolic constituents, antioxidant and antigenotoxic effects of a hydromethanolic extract of the fruiting bodies. Total phenolic content, estimated by Folin-Ciocalteu assay, was found to be 42.33 ± 0.18 mg GAE/g. Protocatechuic and vanillic acids were detected by HPLC-DAD-ESI-MS. The extract showed good free radical scavenging and reducing capacities (EC 50 = 64.3 ± 0.2 and 61.54 ± 0.46 μg/mL, respectively). In normal Vero cells, the extract (100, 200 and 300 μg/mL) showed no genotoxic potential and moreover, almost completely protected DNA against H 2 O 2 -induced damage (2.09–7.91% tail DNA) (24 and 48 h pre-treatment). Taken together, the results of our study show that Ramaria largentii extract is devoid of genotoxicity and has a remarkable DNA protective activity against H 2 O 2 -induced damage.
