TI:Edible and poisonous mushrooms: an introduction.

AU:Hall-IR; Buchanan-PK; Yun-W; Cole-ALJ

SO:1998, 189 pp.; 170 col. pl.; 221 ref.

PB:Crop & Food Research; Christchurch; New Zealand

LA:English

AB:After an introductory chapter describing how mushrooms grow, their persity and nomenclature, one chapter each is dedicated to the cultivation of saprobic mushrooms (including Agaricus bisporus and A. bitorquis, Lentinula edodes, Pleurotus spp., Auricularia spp., Volvariella volvacea, Flammulina velutipes, Tremella fuciformis and Pholiota nameko) and mycorrhizal mushrooms. The remainder of the book is devoted to collection and identification of >200 edible and poisonous mushrooms commonly found in New Zealand and Australia. There is a subject index.

TI:Genetic homogeneity of cultivated strains of shiitake (Lentinula edodes) used in China as revealed by the polymerase chain reaction.

LA:English

AB:Nineteen strains, which are used for spawn production in farms throughout mainland China, were characterized by 3 arbitrarily-primed PCR profiles (AP-PCR), 7 RAPD profiles and 5 RFLP patterns of PCR-amplified rDNAs. For AP-PCR, 4-14 DNA bands were amplified for a particular strain while 1-9 DNA bands were amplified using RAPD. Among them only 3 of the strains tested showed different amplification profiles with most of the primers used. The other strains showed small differences in 3 or fewer DNA amplification profiles. All strains showed identical rDNA-RFLPs. The study indicated that cultivated strains of shiitake in China are genetically very homogeneous, a similar situation to that in cultivated Agaricus bisporus and Volvariella volvacea. However, this collection of L. edodes covers an enormous geographical area (?700 km N to S and 700 km E to W) further reinforcing the finding that the shiitake industry in China is based on an extremely small gene pool. In comparison, 3 wild strains collected in Fujian, SE China showed more variable amplification profiles.

AU:Singer,-R; Harris,-B

SO:1987, Ed. 2, 389 pp.; 17 pp. ref., many pl. Koenigstein, German Federal Republic; Koeltz Scientific Books.

LA:English

AB:The first part of the book was written by Rolf Singer and is based on the first edition. Titles of its 13 chapters include the following: Botany of mushrooms and truffles; Botany of the cultivated white mushroom and other cultivated species of Agaricus; Cultivation of Agaricus bisporus and related species; The paddy straw mushroom (a variety of Volvariella volvacea) and its cultivation in the tropics; Shiitake and its cultivation in East Asia; Truffles (including Tuber) and the cultivation of truffles in France; Wood-inhabiting basidiomycetes (9 species described) and other earth-inhabiting mushrooms; Weeds and weed fungi (in mushroom beds and truffle sites, and their control); Mushroom and truffle diseases (of cultivated white mushroom, paddy straw mushroom, shiitake and the mycorrhizal basidiomycetes, and their control); Pests; and Mushrooms and truffles for human consumption and other uses (e.g. as animal feed and in pharmacy).An appendix to the book (page 283), written by Bob Harris, is concerned with the developments, improvements and expansion (both commercial and in range of species) in mushroom culture which have occurred in the past 25 years. Its 10 chapters are entitled: Agaricus bisporus; Volvariella volvacea; Shiitake, Lentinus edodes [Lentinulus edodes] (on log and sawdust substrates); Truffles; Wood-inhabiting fungi; Virulence testing of wood-inhabiting fungi; Terricolous and litter fungi; Nutritional aspects of fungi; Medical aspects; and Economic aspects.

TI:Segregation of genotypically perse progeny from self-fertilized haploids of the Chinese straw mushroom, Volvariella volvacea.

AU:Chiu-SiuWai; Moore-D; Chiu-SW

SO:Mycological-Research. 1999, 103: 10, 1335-1345; 58 ref.

LA:English

AB:The electrophoretic karyotype of the Chinese straw mushroom, Volvariella volvacea, was determined. The haploid strain V34 of V. volvacea has 15 chromosomes ranging in size from 1.4 to 5.1 Mb. No chromosomal polymorphism in terms of size and number was seen in either of 2 growth stages: vegetative mycelia or fruit-body gill tissues. DNA fingerprints were prepared by the arbitrarily-primed polymerase chain reaction. Those obtained from different stages during fruit-body morphogenesis were identical. However, variation in DNA fingerprints was evident in protoplast regenerants derived from the same vegetative mycelium. Thus the haploid mycelium of strain V34 is heterokaryotic but the bulk genotype is stable during fruit-body development. F1 and F2 progenies germinated from the haploid, uninucleate basidiospores from self-fertilized fruit bodies also regularly segregate a range of mycelial morphological variants as well as phenotypic variation revealed by DNA fingerprints. The known mechanisms that generate genetic variation are reviewed and a novel mechanism that could account for the 1:1 segregation ratio of self-fertile to self-sterile progeny regularly obtained from selfed V. volvacea fruit bodies is proposed.

LA:English

AB:The topography and agro-climate of the Manipur State, India provide a conducive condition for the growth of different fleshy fungi. Some of these fleshy fungi are not only edible but have high food value as well as income generating potential for the local tribal inhabitants of the State. Intensive survey of the forests and local markets was conducted in all the districts of the State for two years (1997-1999). Altogether 33 species of wild edible fleshy fungi were collected and identified. The most common species were Auricularia delicata, A. polytricha, A. auricula, Agaricus campestris, Gomphus floccosus, Scleroderma verrucosum, Schizophyllum commune, Lentinula edodes, L. lateritia, Lentinus cladopus, L. tigrinus, L. sajor-caju, Termitomyces eurrhizus [T. eurhizus], T. robustus, T. clypeatus, T. microcarpus, Favolus spatulatus [F. spathulatus], Vascellum pratense, Volvariella volvacea, Tricholoma giganteum [Macrocybe gigantea], Ramaria sp., Pleurotus sp., Lactarius princeps, etc. Sixteen species were found in the markets during March to September. Two genera viz., Auricularia and Schizophyllum were available in the market in dried form throughout the year. The district-wise quantity and market prices are provided. Possibility of large-scale export of commercially important species such as Lentinula edodes (Japanese Shiitake) is envisaged.

AB:Pure cultures of the V. volvacea strain CI/70/52 were grown on test tube slants of potato dextrose sugar, and the inoculum was multiplied in large bottles filled with moistened paddy straw. The bottle inoculum was used to inoculate 3 layers of a four-tiered straw bed. The stages in the development of a carpophore were classified on the basis of the time sequence, length, breadth and length/breadth ratio. This classification may be used to provide a basis for harvesting the buttons at the most desirable stage.
