Fourteen species of the genus Polyporus were identified based on the collection from lowland and mountain areas of south Western Siberia. The list of identified species are presented. Key to identification of fungi is given. Pictures of fruit bodies are given. The analysis of the substrate, habitat and zonal distribution was carried out. Substrate of fungi represented 13 species of angiosperms, 3 species of gymnosperms woody plants and steppe grasses. The largest number of species growing on willows, aspen and birch. Ten species were found in the plain area, 14 species were found in the mountain systems. Most diversity of species observed in the aspen-fir forests “Chernevaya taiga”.

The present investigation focuses on the evaluation of fungicidal potential of a foliose lichen Heterodermia leucomelos (L.) Poelt against five strains of phytopathogenic fungi. Acetone, methanol and chloroform extracts of test lichen were screened against pathogens Aspergillus niger, Aspergillus flavus, Fusarium oxysporum, Fusarium solani, Colletotrichum falcatum by the Disc – Diffusion Assay. MIC values of the extracts were determined by Broth tube dilution method. Among the three solvents acetone and methanol exhibited highest activities. Mean diameter of zones of inhibition for acetone and methanol extracts ranged from 18.0±0.0 to 28.6±0.3 mg/ml and 12.3±0.6 to 24.6±1.2 mg/ml. respectively with MIC values ranging from 0.19 to 1.56 mg/ml. Tukey’s multiple comparison test provides significant differences (at p<0.05 and 0.01) in the activity of the extracts towards different phytopathogens. The results proved that the lichen holds high medicinal properties and can be a rich source of potential natural antimicrobial agents.

Soil microfungal diversity was studied with the objective to investigate variations in fungal communities along 12 diverse vegetation zones located at different altitudinal gradients in Arunachal Pradesh and to check whether the environmental conditions have an effect on the soil fungal community. Ten soil samples were collected from 0-30cm depth in each forest type and their physico-chemical properties such as pH, temperature, bulk density and organic carbon content analyzed using standard techniques. Serial dilution methodology was used for the isolation of soil fungi in Rose Bengal agar media. A total of 112 fungal types under 59 genera and 88 species were recorded from the selected soils. Altitudinal gradient and bulk density was found to have a negative effect, while soil temperature and soil pH had positive effects on the soil fungal communities. Sub-tropical evergreen forests showed maximum fungal diversity followed by tropical evergreen forests. Overall, Oidiodendron followed by Acremonium, Cladosporium, Humicola, Aspergillus and Penicillium were found dominant fungal genera in majority of soil samples. Distribution of Beauveria, Blastomyces, Cercospora, Metarrhizium and Rhizomucor were limited to particular soil type. Altitudinal gradient together with associated vegetation and soil physico-chemical parameters determine soil fungal distribution.

Trichoderma is reported to be one of the most widely distributed soil fungi and the biocontrol potential of Trichoderma has been studied against a wide range of plant pathogenic fungi. In the present study T. erinaceum was screened for antifungal activity against seven selected plant pathogenic fungi and for chitinase and glucanase production. In antifungal assays highest mean percent inhibition was observed against the pathogenic fungus Rhizoctonia solani (72.66 % ±7.6). Molecular characterization of rDNA of ITS region was made for identification and it was identified as Trichoderma erinaceum.
Keywords: biocontrol – chitinase – glucanase – ITS

This paper gives an account of five Psathyrella species from Punjab state in India along with key for their identification. The collections of the identified taxa were obtained from a variety of coprophilous habitats having different herbivorous dung types. These belong to Psathyrella kauffmanii var. kauffmanii, P. vanhermanii, P. fimicola, P. sphaerocystis and P. flocculosa. For all the taxa, dung types on which they were found growing are mentioned. Psathyrella kauffmanii var. kauffmanii, P. vanhermanii, P. sphaerocystis and P. flocculosa are new fungus records for India. The taxonomy of all these 04 new records is discussed along with the drawings of morphological and anatomical features and their distinctive characters are described and compared with similar taxa.

10. Ecological niche modeling of some Costa Rican myxomycetes

Ecological niche modeling has not been used extensively in studies of myxomycetes but can provide important information for research efforts to develop a better understanding of the ecology of these organisms. With a dataset of myxomycete records for the five most commonly recorded species in Costa Rica, a series of probability distribution models was generated using the maximum entropy technique. The latter was carried out with the objective of evaluating the usefulness of such protocols to provide feedback for future research. Models showed Arcyria cinerea and Didymium iridis to have wider but more moderate probability distributions in comparison with Physarum compressum, Didymium squamulosum and Hemitrichia calyculata. Elevation was the variable that contributed the most to all ecological niche models, but a greater number of studies have been carried out in Costa Rica at high elevations. As such, it seems that the models showed the need for low elevation systematic surveys more realistically than providing a representation of the niche and distribution for the species being considered. However, this study does serves as baseline for future assessments of myxomycete distribution patterns in the framework of climate change.
