3. Type study of Calvatia lachnoderma from Brazil

Authors: Cortez VG, Alves CR

Recieved: 09 October 2012, Accepted: 10 October 2012, Published: 09 November 2012

Calvatia lachnoderma was described by Patouillard in 1907 based on material collected by P.F. Noack, in the State of São Paulo, southeast Brazil. The species was not considered in accounts of gasteroid fungi from Brazil, nor in recent monographs on the genus. We examined type material from Farlow Herbarium and concluded that it is a good species in the genus, based mostly on peridium texture, basidiospore size/shape and ornamentation under scanning electron microscopy (SEM). The holotype is the only available material. A description of the microscopic features is provided, as well as SEM analysis of the basidiospores and brief taxonomic discussion.

Keywords: Agaricomycetidae – gasteromycetes – puffball – taxonomy

 

4. Biodiversity of laccase producing fungi in Egypt

Authors: Abdel-Azeem AM, Salem Fatma M

Recieved: 08 September 2012, Accepted: 30 October 2012, Published: 15 November 2012

Laccase enzyme (EC 1.10.3.2) is a benzenediol, a multi-copper enzyme, and one of the three main ligninases that differs from the others in its ability to catalyze the oxidation of lignin components. It is widely distributed in fungi and because of its importance in bioremediation; the search for fungal laccases with different properties and potential applications is still on-going. In view of its importance in large scale application, the present endeavor is to search for highly efficient laccase producing fungi from different environmental habitats in Egypt. Cultural conditions such as temperatures, pH, carbon sources and nitrogen sources were optimized for the production of high extracellular laccase activity. By screening sources under investigation namely: soil, wood, seaweeds, sponge, ascidia, drifted decaying wood, plants and miscellaneous materials it was possible to encounter as many as 60 species belonging to 33 genera. Zygomycota represented by six species (10.16% of the total species number), teleomorphic Ascomycota (9 species, 15.25%), anamorphic Ascomycota (44 species, 74.57%) and Basidiomycota (1 species, 1.69%). Soil showed the highest Simpson’s species diversity index of 0.83 while contaminated wax samples and Adiantum capillus-veneris showed the lowest value (0). All isolated taxa were tested for laccase production using a qualitative plate assay method by using guaiacol as color indicator. Sixteen isolates showed positive reaction indicating a lignin-degrading potentiality and out of them eight measured the highest zone diameter with high oxidation scale. The most promising taxa were endophytic namely: Chaetomium globosum, Phoma exigua, Thanatephorus cucumeris and Sordaria fimicola. pH 7, incubation temperature 30oC, 1% maltose and 0.3% peptone supported the highest biomass and laccase production for Chaetomium globosum.

6. Optimal growth conditions for basidiospore germination and morphogenesis of Philippine wild strain of Lentinus tigrinus (Bull.) Fr

Authors: Dulay RMR, Cabrera EC, Kalaw SP, Reyes RG

Recieved: 04 September 2012, Accepted: 08 November 2012, Published: 19 November 2012

Lentinus tigrinus is a basidiomycetous fungus that is usually found growing in clusters on fallen logs of the forest. This mushroom is considered as the local counterpart of shiitake (L. edodes), since it is endemically growing in the tropical countries such as the Philippines. In our intention to develop production technology for this mushroom, we determined the influence of nutritional (local culture media) and physical (pH, aeration, illumination and temperature) factors for basidiospore germination and morphogenesis of wild strain of L. tigrinus. Basidiospores of L. tigrinus germinated efficiently in a submerged culture with potato sucrose broth (pH 7.5) incubated in a lighted air-conditioned room (23˚C) with a mean of 91.33% after 10h of incubation. A peculiar type of germination process was evident as the spore coat was retained, elongated and eventually became part of the hypha. A sequence of significant developmental stages; mycelial coat thickening, swelling formation, browning and primordial initiation arises prior to basidiomata maturation and basidiospores liberation. L. tigrinus is a further addition to the list of Philippine wild edible mushrooms with great potential for cultivation.

Keywords: basidiospores – Lentinus tigrinus – morphogenesis – nutritional requirement

8. Myxomycetes of Stewart Island, New Zealand

Authors: Stephenson SL, Stephenson BC, Stephenson RJ

Recieved: 25 October 2012, Accepted: 30 October 2012, Published: 23 November 2012

Records of myxomycetes obtained as a result of field surveys carried out on Stewart Island in February and April of 1998 were supplemented with records of species appearing in moist chamber culture on samples of various types of dead plant material collected during the field surveys and a small set of samples collected in 2006. In addition, previously published records and all known herbarium records of these organisms were compiled in an effort to produce a comprehensive checklist of the myxomycetes for this region of New Zealand. The assemblage of 51 species reported from Stewart Island is more diverse than that of any of the subantarctic islands or island groups (Macquarie, Campbell, Auckland and Snares) but is much less diverse than mainland New Zealand.
