Basidiomes of homothallicArmillaria mellea complex were discovered in the forests of Hokkaido. Their monosporous isolates showed partial compatibility with North AmericanA. mellea s. str. haploid testers. The morphological characteristics of basidiomes differed from other temperateA. mellea s. str. in several aspects. Here, JapaneseA. mellea s. str. is reclassified asA. mellea subsp.nipponica and its basidiome morphologies and habitats are described. 
Seven Armillaria species identified from Hokkaido Island, northern Japan
Sixty-two isolates from basidiocarps of Armillaria spp. were obtained from Hokkaido Island, northern Japan. Six species (Armillaria cepistipes, A. gallica, A. nabsnona, A. ostoyae, A. sinapina, and
Armillaria species associated with Gastrodia elata in Japan
Clear isozyme profiles of esterases were obtained with all isolates except one and could be used for identification of the Armillaria species in Hokkaido as a useful complement to the mating-type method.
Armillaria jezoensis, a new symbiont ofGaleola septentrionalis (Orchidaceae) in Hokkaido
NineArmillaria isolates obtained from the roots of Galeola septentrionalis in Hokkaido were identified as A. jezoensis by means of mating tests, showing better mycelial growth and rhizomorph formation on GDA medium.
Genetic variation in Armillaria mellea subsp. nipponica estimated using IGS-RFLP and AFLP analyses
The results suggest that the large distribution of the isolates within the same subgroup were established via the basidiospore from a common parental strain.
A study on intersterility groups of Armillaria in China.
Mating tests were used to identify 282 basidiocarp specimens of Armillaria collected in 15 Chinese provinces, mostly in northern and southwestern parts of the country, and the sexual system of 13 taxa is tetrapolar heterothallism.
The phylogenetic position of an Armillaria species from Amami-Oshima, a subtropical island of Japan, based on elongation factor and ITS sequences
An undetermined Armillaria species was collected on Amami-Oshima, a subtropical island of Japan and the phylogenetic analyses showed that this species differs from known Japanese taxa of Armillsaria.
Biological Species of Armillaria in Japan.
The existence of 10 intersterile groups of Armillaria was determined by pairing haploid single spore isolates obtained from 20 basidiocarps from a wide geographic distribution in Japan and compatibility reactions were used to identify these to species.
The nonheterothallic life cycle of Japanese Armillaria mellea
The life cycle ofJapanese Armillaria mellea was studied with regard to basidiomata formation from monosporous cultures, the nuclear behavior during basidiospore formation and germination, and DNA
Population Structure of Basidiomycetes
Despite a common ancestry, it takes a critical microscopic or biochemical examination to recognize the relationship between these groups; they differ radically in gross morphology, life history, and population structure.


Biological species and morphological characteristics ofArmillaria mellea complex in Hokkaido:A. sinapina and two new species,A. jezoensis andA. singula
Three intersterility groups ofArmillaria mellea sensu lato were discovered by examining all pairwise combinations of monosporous isolates of basidiomes collected in Hokkaido. One of them, group IV,
Biological Species and Morphological Characteristics of Armillaria mellea Complex in Hokkaido:A. ostoyae and A. bulbosa
The different morphological forms of Armillaria mellea (V AHL; FR.) KUMMER complex collected in Hokkaido were found to be composed of four intersterility groups or biological species by using all

Identification of Kenyan Armillaria isolates by cultural morphology, intersterility tests and analysis of isozyme profiles
Three groups of morphologically distinct isolates were observed among nine Kenyan Armillaria isolates based on their mycelium and rhizomorphs characteristics, and it was shown that morphologically similar isolates had similar isozyme profiles of esterases but their profiles however differed from those of the European A. ostoyae.
