ABSTRACTDocumented evidence of fungi associated with Mesozoic ferns is exceedingly rare. Three different types of fungal remains occur in a portion of a small, permineralised fern stem of uncertain systematic affinities from the Triassic of Germany. Exquisite preservation of all internal tissues made it possible to map the spatial distribution of the fungi in several longitudinal and transverse sections. Narrow, intracellular hyphae extend through the entire cortex, while wide hyphae are concentrated in the cortical intercellular system adjacent to the stele and leaf traces. Hyphal swellings occur in the phloem and adjacent cortex, while moniliform hyphae (or chains of conidia) are present exclusively in parenchyma adjacent to the stele. No host response is recognisable, but host tissue preservation suggests that the fern was alive during fungal colonisation. The highest concentration of fungal remains occurs close to the stele and leaf traces, suggesting that the fungi either utilised the vascular tissues as an infection/colonisation pathway or extracted nutrients from these tissues. This study presents the first depiction of fungal distribution throughout a larger portion of a fossil plant. Although distribution maps are useful tools in assessing fungal associations in relatively small, fossil plants, preparing similar maps for larger and more complex fossils would certainly be difficult and extremely arduous.

Investigation Period

Air borne fungi of Hill fort region of Channagiri is studied with help of Petriplate exposure method using Pottato dextrose agar media, petriplate exposure time is 15min. Sampling is taken in the month of  January 2013 total 74 fungal colonies represented 07 fungal types were observed during the present investigation period. Environmental condition plays an importance role in the distribution of the fungal spores. Out of 07 fungal species most numbers of fungi are anamorphic groups. The fungal species were Aspergillus, Pencillium, Curvilaria, Cladosporium, Fusarium Rhizopus, Alternaria species were identified. Aspergillus species (47.2%) showing maximum contribution is observed where as Rhizopus shows minimum contribution.DOI: http://dx.doi.org/10.3126/ijasbt.v1i2.8203 Int J Appl Sci Biotechnol, Vol. 1(2): 60-62

ABSTRACTThis survey presents the first high-throughput characterisation of fungal distribution based on ITS2 Illumina sequencing of uncultured microbiome from a 1500 years old perennial ice deposit in Scărișoara Ice Cave, Romania. Of the total of 1 751 957 ITS2 sequences, 64% corresponded to 182 fungal operational taxonomic units, showing a low diversity, particularly in older ice strata, and a distinct temporal distribution pattern. Ascomycota was the major phylum in all ice samples, dominating the 400 and 1500 years old ice strata deposited during the cold Little Ice Age (LIA) and Dark Ages Cold Period, while Basidiomycota was mostly present in 900-years old ice formed during the Medieval Warm Period (MWP). Chytridiomycota and Mucoromycota phyla were present in recently formed and 400-years old ice, respectively. Among the 80 identified genera, Cryptococcus victoriae, commonly found in glacial habitats, was identified in all strata. A positive correlation between fungal distribution and ice conductivity, Ca, Na and Sr concentrations was observed across the ice block, with pH values trailing climate variations during LIA and MWP, respectively. Our record highlighted the presence of a complex climate and environmental-driven fungal community in perennial ice strata accumulated during the last 1500 years in Scărișoara Ice Cave.

Coniferous Needles

Dematious hyphomycetes such as Verticicladium trifidum and Thysanophora penicillioides are examples of equivalent species occupying the same ecological niche in different fungal successions. These two species fructify through the stomata of coniferous needles a few months after litter fall. Litter samples of 23 coniferous species from different European sites were examined to explain the fungal distribution. Thysanophora penicillioides colonized Abies, Picea, Pseudotsuga, and Tsuga needles, whereas V. trifidum was restricted to Pinus and Cedrus. Sometimes other fungal species occupied the stomata: on Pinus pinea needles, the niche was occupied by Cladosporium spp. and Alternaria alternata; Chaetopsina fulva have been found only on Pseudotsuga needles and Thysanophora canadensis on Picea. Verticicladium trifidum was apparently absent on Pinus litters from cold climates (high altitude or latitude) and probably from warm mediterranean regions, suggesting a climatic determinism. However, coexistence of Verticicladium and Thysanophora in some samples or colonization of some Pinus litter by Thysanophora suggests that these distributions result from competition rather than strict host specificity. Key words: ecological niche, equivalent species, conifers, needles, Verticicladium trifidum, Thysanophora penicillioides.
