Ethanolic extracts of oyster mushrooms (Pleurotus pulmonarius, P. ostreatus, P. djamor var. djamor and P. djamor var. roseus) and the split gill mushroom (Schizophyllum commune)were successfully investigated for their antioxidant properties. The study was carried out to determine the capability of the extracts to scavenge 2,2-diphenyl-1-picrylhydrazyl (DPPH) radicals, to determine its reducing ability towards ferricyanide complex (FRAP assay) and to determine the concentration of total phenolic content (TPC) and total flavonoids content (TFC) in the macrofungi ethanolic extracts. Inhibition concentration at 50% (IC50) for each extract to scavenge DPPH radicals was detected from 2.75 mg/ml to 12 mg/mlwhere S. commune from the fourth flush showed the lowest IC50 value among all tested mushrooms. The greatest ability to reduce ferricyanide complex to ferrous form was observed in P. djamor var. djamor at concentration 10 mg/ml in both first (1.23 ± 0.02) and second flushes (1.23 ± 0.00). Meanwhile, the highest TPC was determined in P. djamor var. djamor extract (51.94 ± 0.04 mg TAE/g dry weight of extract) whereas S. commune gave highest reading of total flavonoid content in TFC assay (29.80 ± 0.27 mg QE/g dry weight of extract). All the mushroom samples showed appreciable antioxidant properties which therefore, can be promoted as natural antioxidant preference in food and pharmaceutical industries.

7. Myxomycetes appearing in moist chamber cultures on four different types of dead leaves

Authors: Goad AE,Stephenson SL

Recieved: 22 May 2013, Accepted: 17 July 2013, Published: 30 July 2013

One of the microhabitats available for myxomycetes in temperate forests is represented by the layer of dead plant material that accumulates on the forest floor. This layer, referred to as the litter layer, consists mostly of dead leaves from the trees that make up the forest canopy. In the present study, leaves from four different species of trees (dogwood, red maple, sycamore and white oak) were collected from the upper portion of the litter layer and used to prepare moist chamber cultures to determine whether each type of leaf displayed evidence of supporting a different ecological assemblage of myxomycetes. Leaves were collected on two occasions, January 2012 and January 2013. Forty moist chamber cultures were prepared for each type of leaf on each date, for a total of 320 cultures for the entire study. Most of these (60.6%) yielded some evidence (either sporocarps or plasmodia) of myxomycetes, and 21 species in nine genera were represented among the 244 records of sporocarps recorded from the cultures. Members of the order Physarales made up 59% of all records, with members of the orders Stemonitales (30%) and Trichiales (11%) relatively less important. Major differences existed in the productivity of the two sets of leaf samples (with 2013 appreciably more productive than 2012) and for particular types of leaves (with dogwood characterized by an overall positive value of 92.5% and sycamore with an overall positive value of only 11.5%). Remarkably, the set of samples of sycamore leaves collected in 2013.

Antimicrobial activity of the acetone, methanol and ethanol extracts of some common lichen species such as Usnea longissima Ach., Everniastrum cirrhatum (Fr.) Hale, Peltigera polydactylon (Neck.) Hoffm. and Sulcaria sulcata (Lév.) Bystr. ex Brodo & D. Hawksw., were screened in vitro against six clinically important pathogenic bacteria, Staphylococcus aureus, Streptococcus faecalis, Bacillus cereus, Pseudomonas aeruginosa, Salmonella typhimurium and Escherichia coli by Kirby-Bauer technique of disc diffusion method. Minimum inhibitory concentration was taken out by Broth micro dilution method according to the NCCLS guidelines. Acetone, methanol and ethanol extracts of the investigated lichens showed relatively strong antimicrobial activity against all the gram positive bacteria and two gram negative bacteria.It was found that the inhibition zone of tested bacteria against lichen extracts varied between 7.6 – 30.7 mm diameters. The lowest MIC value was observed to be as low as 6.25 µg/ml against B. cereus of U. longissima. Generally the lichen extracts tested demonstrated antimicrobial effect which suggests a possibility of their use in treatment of various diseases caused by these and similar microorganisms.

12. Kamalomyces mahabaleshwarensis sp. nov. (Tubeufiaceae) from the Western Ghats, India

Authors: Dubey R, Neelima AM

Recieved: 16 April 2013, Accepted: 25 July 2013, Published: 12 August 2013

A new species of Kamalomyces was collected on an unidentified woody twig from Mahabaleshwar, situated in the northern part of Western Ghats of Maharashtra, India. The species belongs to the monotypic genus Kamalomyces which is represented by K. indicus. It can easily be differentiated from the type species of this monotypic genus by variations in the dimension of ascostroma, the spiral arrangement of ascospores in the asci, and the number of ascospore septa (upto 20). Thus Kamalomyces mahabaleshwarensis sp. nov. is introduced with a description and illustrations in this study.

14. The diverse habitats of Hygrocybe – peeking into an enigmatic lifestyle

Authors: Halbwachs H, Karasch P, Griffith GW

Recieved: 28 May 2012, Accepted: 20 June 2013, Published: 17 August 2013

The genus Hygrocybe (Fr.) P. Kumm. is globally distributed. Certain taxa occur on different continents, even in the northern and the southern hemisphere. In Europe grassland is the preferred habitat. The trophic ecology is still unclear. In this review studies and internet sources of about 65 locations distributed from high to low latitudes across all continents in which 16 Hygrocybe species (typically found in Europe) occur have been analysed with regard to habitat types, vegetation and soil properties. The analysis shows that several of the selected Hygrocybe species can cope with a very wide range of habitats. They appear to prefer soils with low fertility, grassland over forests and temperate/boreal climates. Most significantly, waxcaps are found in forest habitats in the absence of grasses, and in grasslands where woody hosts are absent. Mosses are not obligately associated. Their host associations are extremely flexible. A biotrophic lifestyle should be considered.
