“…The actual distribution of the second haplotype is unknown, but Japan and Kamchatka are logical candidates for its distribution. These data resemble fi ndings by Aanen et al (2001) in European and American Hebeloma velutipes Bruchet, Matsumoto et al (2005) with Pleurocybella porrigens, and Terashima et al (2006) with Armillaria mellea subsp. nipponica Y.C.…”

The Pacifi c Ocean and the "Pacifi c Rim" include a vast geographic area and most categories of the earth's ecological niches. As could be expected, macrofungi conform to many distribution patterns, some of which are discussed in this article. An introduction to species concepts and some other ancillary methodological considerations is followed by examples of some distributional patterns: Gondwanan, Transberingian, and island biogeographic. Some considerations of changing distributional patterns are also discussed: widening distributions, probable human mediation, and some unique cases that seem not to conform to accepted patterns. Not surprisingly, we conclude that concerted future collecting and comparison of specimens using multiple methodologies offer the only hope for understanding mushroom distributions, regardless of the geographic area of interest.

“…The IGS domain, which evolved the fastest, was always applied for the analysis of the genetic diversity within species. In recent years, the IGS region has been successfully applied to study the genetic diversity of several edible mushrooms, such as Ferula sinkiangensis [11], Armillaria mellea [20], Pleurotus eryngii [21], Tuber borchii [12] and Rhodocollybia laulaha [13].…”

Background: For the crossbreeding of Auricularia auricula-judae, selecting the appropriated parents in hybridization is very important. However, the classification and diversity analysis of A. auricula-judae has been equivocal, due to the similarity of the fruiting body morphology and its susceptibility to environmental influences. For this purpose, the molecular diversity of 32 A. auricula-judae commercial cultivars in China was analyzed by using the nuclear ribosomal DNA intergenic spacer. Results: The complete nuclear rDNA gene complex of A. auricula-judae isolate is 11,210 bp long, and contains the 18S, 5.8S, and 28S rRNA gene as well as the ITS and IGS regions. Based on the sequence data, four more effective primer combinations for the IGS region of A. auricula-judae were designed. Nucleotide sequence variation in the IGS among 32 A. auricula-judae commercial cultivars in China sorted into three strongly supported clades, which is correlated with geographical regions. Most strains originated from the same area were with a narrow genetic basis and could possibly be domesticated from the local wild-type strains. Conclusion: The grouping information obtained in the present work provides significant information for further genetic improvement in A. auricula-judae, and suggested that the IGS region can be used as an excellent tool for identification of genetic variation.

“…Vos et al (1995) developed amplifi ed fragment length polymorphism (AFLP) analysis based on polymerase chain reaction (PCR) amplifi cation of DNA restriction fragments. AFLP analysis has been utilized to examine genetic differences among strains for a few mushrooms such as Armillaria species (Terashima et al 2001(Terashima et al , 2006a, L. edodes (Terashima et al 2002;Matsumoto et al 2003) and Tricholoma matsutake (S.
