Wood-rotting fungi were collected from two forest stands - a disturbed (Lower Kitsubozou) and an undisturbed forest stand (Mount Puliebadze) of Kohima, Nagaland in India. A survey and collection of wood-rotting fungi were done during the months of October and November, 2013 (Autumn); January and February, 2014 (Winter); March and April, 2014 (Spring). A total of 32 species belonging to 18 families were identified based on the macro and micro morphology of the fruiting bodies. Three species belong to phylum Ascomycota and 29 species belong to phylum Basidiomycota. More wood-rotting fungi were collected from the undisturbed forest stand, Puliebadze than from the disturbed forest stand, Lower Kitsubozou. Of the total species of woodrotting fungi collected, 68.96% species occurred on logs, 17.24% on tree stumps, 15.51% on twigs and 12.06% on living trees. More wood-rotting fungi were collected in Autumn season. Ganoderma applanatum, Microporus affinis and Trametes versicolor were collected in all three seasons.

Gurguripal is a forest based rural area situated in Paschim Medinipur District, West Bengal, India. It is located at 22°25" - 35°8"N latitude and 87°13" - 42°4"E longitude, having an altitude about 60 M. This area represents tropical evergreen and deciduous mixed type of forest dominated mainly by ‘Sal’. The present study deals with the status of mushroom diversity and productivity in Gurguripal Eco-forest. Field survey has been conducted from May 2014 to October 2015 and a total of 71 mushroom species of 41 genera belonging to 24 families were recorded including 32 edible, 39 inedible and altogether 19 medicinally potential mushrooms. The genus Russula exhibited the maximum number of species and the family Tricholomataceae represented the maximum number of individuals.  According to Simpson’s index of diversity, the calculated value of species richness was 0.92 and as to Shannon’s diversity index, the relative abundance of species was found to be 2.206. Evenness of the mushrooms was also calculated as 0.333. The mushroom genera Termitomyces heimii, Astraeus hygrometricus, Leucopaxilus sp., Amanita vaginata, Volvariella volvacea, Agaricus campestris are found as potential food sources to the Santal livelihood in Gurguripal Eco-forest. Wild mushrooms have immense importance in the maintenance of forest ecology and act as an indicator of forest management. In this context the present study opens up new possibilities regarding the exploitation and utilization of wild mushrooms in India.

Indiscriminate disposal of engine oil is considered a serious threat to the environment due to its chemical composition. Pleurotus tuber-regium, an edible mushroom has been implicated in bioremediation and bioaccumulation of compounds from its environment. The study was to assess the effect of engine oil on molecular finger prints of Pleurotus tuber-regium Fr Sing. Loamy soil contaminated with spent and non- spent engine oil at the rate of 2, 4, 6, 8 and 10% concentrations respectively was inoculated with 30g sclerotia. DNA was extracted only from sporophores grown at 2 and 4% oil contamination. Two ITS primers (ITS 1/ITS 4B and ITS 1/ITS 4A) with six RAPD primers (OPM 14, OPL 20, OPK 01, OPA 04, OPD 07 and OPD 11) were used to elucidate variations in the genomic profiles. ITS 1/ITS 4B primer amplified a single band at 600 bp from the fragments while RAPD primers showed PCR product amplifications of variable sizes (500 bp–800 bp). Although similarity existed among fragments from the same contamination level, the dendrogram revealed one major cluster which deviated according to contamination levels irrespective of type of oil; 4% fragments were more closely related than 2%. This indicates that exposure to different doses of oil could affect the molecular finger prints of P. tuber-regium. The implication is that engine oil could cause variations in DNA profile.

Authors: Çolak ÖF, Kaygusuz O, Işıloğlu M

Recieved: 05 February 2017, Accepted: 10 March 2017, Published: 13 March 2017

In this study, two Lactarius species are reported which form mycorrhizal associations with Cistus laurifolius. Of these, Lactarius tesquorum is a rare species in the mycota of Turkey, and L. cistophilus is a new record. Microscopic drawings and detailed descriptions of the taxa are given together with morphological photographs.

5. Soil physicochemical properties and its relationship with AMF spore density under two cropping systems.

Authors: Nongkling P, Kayang H

The objective of the study was to determine the soil physicochemical properties and its relationship with AMF spore population associated with upland rice grown under mixed and mono cropping systems. The rhizosphere soil of upland rice from the two cropping systems were collected for analysis of soil moisture content, soil temperature, pH, organic carbon, total nitrogen, available phosphorus, exchangeable potassium and AMF spore population. For isolation and enumeration of AMF spores, wet sieving and decanting method was followed. Mixed cropping harboured higher AMF spore population relative to mono cropping. Soil moisture content, total nitrogen and organic carbon was higher in mixed cropping system, whereas soil temperature, pH, available phosphorus and exchangeable potassium were higher in mono cropping system. Among the soil properties analysed, significant negative relationship of spore density with soil pH, available phosphorus and exchangeable potassium was observed in both the cropping systems and a significant positive relationship of spore density with moisture content and organic carbon was observed only in mixed cropping system. The present study suggests that cropping systems and its associate soil physicochemical properties influenced the spore population of AMF in the rhizosphere soil of upland rice.

7. How many myxomycete cells are there in wood?

Authors: Taylor KM, Feest A, Stephenson SL

Recieved: 19 August 2016, Accepted: 15 March 2017, Published: 22 March 2017

Following proof that myxomycetes are to be found within wood we have counted the minimum numbers of cells in four surveys including wood that has not been in contact with the ground (three sites and two species of tree; one site samples from the ground and aerial).  We found that 1). Numbers of cells increased with decay as measured by the C:N ration; 2). The largest population density was >64,000 cm-1; 3). The preponderance of protists in wood that had not touched the ground were myxomycetes and the aerial dispersal of dry spores gives a colonization advantage to myxomycetes and 4). It is possible to find widely differing densities of myxomycetes in the same piece of wood.

Keywords: aerial dispersal – protozoa – slime moulds – wood decay
