“…Among them, A. gallica was the most common in Hokkaido, Japan (Cha and Igarashi 1995). This species is well known as a saprobe and produces abundant rhizomorphs in soil (Roll-Hansen 1985). Terashita and Chuman (1989) recognized five biological species (A. borealis, A. gallica, A. cepistipes, A. mellea, and A. tabescens) from Gaelola septentrionalis, an achlorophyllos Armillaria calvescens (AY213560) Armillaria calvescens (AY213561) Armillaria calvescens (AY213559) Armillaria gallica (AY213569) Armillaria gallica (AY213570) Armillaria gallica (AY213571) Armillaria gallica (AY213568) Armillaria sinapina AY213567) Armillaria sinapina ( Neighbor-joining phylogenetic tree showing relationship between symbionts isolated from P. umbellatus and North American Armillaria species based on DNA sequences of internal transcribed spacer 1, 2, and 5.8S rDNA.…”

The sclerotia of Polyporus umbellatus were collected from three locations in Japan and three locations in China. All the collected sclerotia were adhered to by rhizomorphs of the symbionts. When the sclerotium of P. umbellatus was cross sectioned, the internal part of the sclerotium was cream colored, and many black regions surrounding the invading rhizomorphs were observed. The surrounding zone contained string-like, gelatinous masses composed of hyphae, and its outside was brown in color. All isolates were similar in colony morphology and grew well on PDA medium with well-developed rhizomorphs. All the isolates showed typical morphology of Armillaria. The isolated fungi were identified via the ITS region of the nuclear ribosomal DNA sequence. Phylogenetic analysis based on the neighbor-joining method showed that all the isolates clustered with fungi belonging to Armillaria species. Among them, five species (A. sinapina, A. calvescens, A. gallica, A. cepistipes, and A. nabsnona) and the symbiont formed a highly supported clade. We report on the case where Armillaria has a relationship in the sclerotium of Polyporus umbellatus.

“…Biological species from Europe and North America have been identified (Anderson, 1986;Anderson and UIIrich, 1979;Anderson et al, 1980;Bdrub~ andDessureault, 1987, 1989;Hansen, 1985;Volk et al, 1996). In Japan, at least eight biological species have been reported (Cha and Igarashi, 1995a;Cha et al,1992Cha et al, , 1994Nagasawa et al, 1991).…”

Identification of Armillaria species from Hokkaido by analysis of the intergenic spacer (IGS) region of ribosomal DNA using PCR-RFLP

et al. 1998

The intergenic spacer (IGS) region, which is located between the 3' end of 26S ribosomal DNA (rDNA) and the 5' end of 5S rDNA, of six Armillaria species from Hokkaido was investigated using polymerase chain reaction-restriction fragment length polymorphisms (PCR-RFLP). Restriction with only Alu I could distinguish A. mellea subsp, nipponica from the other species. With Alu I and Dde I, A. ostoyae and A. gallica could be distinguished from the other species. Digestion with Alu I resulted in two patterns (types A and B) of A. singula and three patterns (types A, B, and C) of A.[ezoensis. One pattern (type B) of the former species and two patterns (types B and C) of the latter species were each different from those of the other species. Armillaria sinapina gave only one Alu I digestion pattern, which was identical to that of A. jezoensis (type A) and A. singula (type A). However, by digestion with Dde I, A. singula (type A) could be distinguished from A. jezoensis (type A) and A. sinapina.

“…Decay fungi of the genus Armillaria found in this part of Sweden include Armillaria borealis Marxmüller and Korhonen, Armillaria cepistipes Velenovsky, and Armillaria ostoyae (Romagnesi) Herink (Korhonen, 1978;Guillaumin et al, 1985;Roll-Hansen, 1985). In this study the genus Armillaria has not been determined to species.…”

The occurrence of fungi in the underground parts of 1-and 2-year-old conifer stumps (Pimis sylveslris and Picea abies) was studied in two clear-felled areas of eastern Uppland in Sweden, and most fungal isolates were identified to species.Decay fungi (Basidiomycetes) were more frequent in spruce stumps than in pine stumps, and their incidence was highest in 2-year-old stumps. The occurrence of blue-stain fungi and hyaline mycelia did not differ significantly between stumps of different species or age. Within stumps, decay fungi were most frequent in large roots close to the cut surface, whereas blue-stain fungi and hyaline mycelia were most abundant in small roots. The occurrence of yeasts, bacteria and fast-growing moulds was also recorded.
