1. Myxomycetes of Maharashtra: two new species of Diderma Pers

Authors: Mishra RL, Phate PV, Ranade VD

Recieved: 02 August 2013, Accepted: 21 August 2013, Published: 31 December 1969

The present paper provides the description and illustrations of two new species of Diderma (D. non-columellata sp. nov. and D. physarinum sp. nov.) that are characterized by the absence of columella in the first instance and the presence of a large columella bearing a number of peg-like protuberances running through the sporangial cavity up to the peridium in the second instance. The latter condition is similar to what is found in the genus Physarina respectively.

Recieved: 05 August 2013, Accepted: 22 August 2013, Published: 07 September 2013

In this paper, an annotated checklist of macrofungi from Őrség National Park, West Hungary, is provided. A total of 726 macrofungi taxa representing 214 genera, 84 classes and 2 phyla (Asco- and Basidiomycota) were revealed. Sixty-one macrofungi species were new to the mycobiota of Hungary. Sporocarps were collected three times (in May, August and September–October) between 2009 and 2010 in 35 (40 m × 40 m) forest stands with different tree species compositions. Preferred tree species compositions and substrata of registered macrofungi are also listed.

8. Plant signalling and the role played by photosynthates in mycorrhizal recruitment

Authors: Thomas PW, Jones CL

Recieved: 22 August 2013, Accepted: 10 September 2013, Published: 27 September 2013

Previous research into the recruitment and regulation of ectomycorrhizal partnerships have found both secondary compounds such as IAA and hypaphorine and the physical limitation of nutrient exchange to play important roles. In this study, Quercus robur seedlings displaying a normalized growth pattern and mutant individuals lacking photosynthetic apparatus were inoculated with a sporal treatment of Tuber aestivum in order to elucidate a role for photosyntheticly induced signals in mycorrhizal recruitment. We found that Quercus robur that lacked an above-ground stem system and therefore the apparatus for photosynthesis recruited no Tuber aestivum, while those with a stem complex showed normal-high mycorrhizal recruitment therefore leading to the conclusion that photosynthates and photosynthetically induced signalling compounds such as phytohormones play an important role within the initial recruitment of mycorrhiza to plants.

Keywords: ectomycorrhiza – hypaphorine –IAA – mutualism – Photosynthates – Quercus robur – Tuber aestivum syn – uncinatum

 

9. Determination of heavy metals in Pleurotus ostreatus (Oyster mushroom) and Termitomyces clypeatus (Termite mushroom) sold on selected markets in Accra, Ghana

Authors: Quarcoo A, Adotey G

Recieved: 01 August 2013, Accepted: 29 August 2013, Published: 30 September 2013

This study was conducted to determine the presence and concentration of heavy metals Cd, Fe, Pb, As, and Hg in Pleurotus ostreatus (oyster mushroom), and Termitomyces clypeatus (termite mushroom) from markets in Greater Accra region (Kaneshie market, Madina market and Makola market), Ghana by using VARIAN AA240 FS- Atomic Absorption Spectroscopy (AAS). The levels of heavy metals in the P.ostreatus, and T.clypeatus ranges from 0.35 to 0.57mg/kg for Cd, 43.77 to 65.19 mg/kg for Fe, 0.04 to 0.23mg/kg for Pb, 0.04 to 0.10mg/kg for As and 0.04 to 0.04mg/kg for Hg. T.clypeatus was observed to have the highest concentration of all the heavy metals. While cadmium and mercury were above the recommended limits set by organizations like the European Commission and the WHO/FAO Expert Committee on Food Additives, none of the values obtained here are considered health risks because of the large amounts of these mushrooms that must be consumed for heavy metal toxicity to kick in.

Keywords: atomic absorption – spectroscopy – heavy metals – mushrooms – Pleurotus ostreatus – Termitomyces clypeatus

 

10. The international conservation importance of Welsh 'waxcap' grasslands

Authors: Griffith GW, Gamarra JGP, Holden EM, Mitchel D, Graham A, Evans DA, Evans SE, Aron C, Noordeloos ME, Kirk PM, Smith SLN, Woods RG, Hale AD, Easton GL, Ratkowsky DA, Stevens DP, Halbwachs H

The large decline in plant and animal diversity of semi-natural grasslands resulting from the introduction of modern agricultural practices in the 1940’s has been well documented and such changes are also suspected of causing the decline in the abundance and diversity of macrofungi in these habitats. We conducted repeated surveys at 48 selected grassland sites around Wales to record the presence and abundance of fruitbodies (FBs) of grassland macrofungi belonging to the taxa Clavariaceae, Hygrocybe, Entoloma, Geoglossaceae, Dermoloma (also Porpoloma and Camarophyllopsis spp.) which are grouped collectively as “CHEGD” fungi (acronym of group names) and considered typical of nutrient poor ‘waxcap’ grasslands. A total of 111 CHEGD species (of the ca. 200 species previously found in UK/Ireland) were recorded. That these included one species unknown to science, 14 new to Wales including two new to the UK attests to the extent of past under-recording. Phenological differences in fruiting were found between Entoloma and Hygrocybe spp., and patterns of occurrence at the sites correlated well with numbers of records from the Fungal Records Database of Britain and Ireland. The recent post-glacial history and high human population densities have generally resulted in lower levels of biological diversity in north-western Europe than in other parts of the world. Compared with current data from other European countries and globally, Welsh grasslands host particularly diverse macrofungal communities, yet the organisms continue to attract little attention from mainstream conservation bodies, whilst much conservation effort is lavished on species which are relatively common elsewhere.

11. A new non-isidiate Leptogium species with transverse septate ascospores from Southeastern Brazil

Authors: Kitaura MJ, Marcelli MP, Hora BR, Jungbluth P

Recieved: 28 June 2013, Accepted: 12 September 2013, Published: 08 October 2013

A non-isidiate Leptogium species with transverse septate ascospores is described as new. The species was collected in Serra da Mantiqueira and initially identified as L. megapotamicum, but the study of the type specimen demonstrated differences in the tissues of the apothecia, which supported the observed morphological variations of the thalli and apothecia found by our descriptive protocol.

Keywords: amphithecia – columnar hyphae – section Leptogiopsis – subhymenial tissue

15. Indonesian oleaginous yeasts isolated from Piper betle and P. nigrum

Authors: Kanti A, Sukara E, Kadarusman L, Sukarno N, Boundy-Mills K

Recieved: 01 July 2013, Accepted: 06 October 2013, Published: 23 October 2013

In this study, 71 strains of yeast were isolated from Piper betle and P. nigrum. Isolates were identified using sequence analysis of the D1/D2 region of large 26S ribosomal subunit rDNA. They belong to 25 species in 11 genera. Strains Cryptococcus luteolus InaCC Y-265, Candida orthopsilosis InaCC Y-302, and Candida oleophila InaCC Y-306 could accumulate more than 40% of lipid per g of cell biomass on a dry weight basis. The fatty acids observed were primarily palmitic acid (C18:1), palmitoleic acid (C16:1), stearic acid (C18:0), oleic acid (C18:1) and linolenic acid (C18:2). The fatty acid profiles suggest that these yeasts may be good candidates for biodiesel production, as they are similar to the fatty acids of plant oils currently used for biodiesel.

Keywords: Candida orthopsilosis – Candida oleophila– Cryptococcus luteolus–fatty acid
