Polyporus accommodates morphologically heterogeneous species and is divided into six infrageneric groups based on macromorphological characters. On the other hand allied genera have macro- and microscopic characters similar to those of Polyporus. The phylogenetic relationships of Polyporus and allied genera were established from sequences of RNA polymerase(More)
Results On the T2-T3 continuum Chinese: the perceptual boundary is distinct and there is a significant tendency of the interaction between tone contexts and the identification of T-2 and T-3 (FT2 (1, 7) = 6.44, p<0.05; FT3 (1, 7) =6.10, p<0.05). To make it more concise, the perceptual boundary between T2 and T3 emerges later along the continuum when the(More)
Tricholoma matsutake (S. Ito & S. Imai) Singer and its allied species are referred to as matsutake worldwide and are the most economically important edible mushrooms in Japan. They are widely distributed in the northern hemisphere and established an ectomycorrhizal relationship with conifer and broadleaf trees. To clarify relationships among T. matsutake(More)
The phylogenetic relationships of two Japanese Heterobasidion species, H. annosum sensu lato and an undetermined species, were revealed based on three gene loci, glyceraldehyde 3-phosphate dehydrogenase (gpd), heat shock protein (hsp) and elongation factor 1-alpha (ef). The tree, based on combined data of gpd, hsp and ef, showed that Japanese H. annosum(More)
Tricholoma matsutake is the most commercially important edible mushroom in pine forests in Japan. Tricholoma bakamatsutake and T. fulvocastaneum, species closely related to T. matsutake, occur in Fagaceae forests. We examined ectomycorrhizal (EM) formation by these Tricholoma species by in vitro synthesis among seven strains (two of T. matsutake, four of T.(More)
“Matsutake” mushrooms are formed by several species of Tricholoma sect. Caligata distributed across the northern hemisphere. A phylogenetic analysis of matsutake based on virtually neutral mutations in DNA sequences resolved robust relationships among Tricholoma anatolicum, Tricholoma bakamatsutake, Tricholoma magnivelare, Tricholoma matsutake, and(More)
The distribution of Phellinus noxius is currently limited to tropical and subtropical regions of Southeast and East Asia, Oceania, Central America, and Africa. The ability of this pathogen to produce disease in temperate climates is unknown. We examined the pathogenicity of Phellinus noxius on four important conifer plantation species grown under temperate(More)
We analyzed the sequences of three DNA regions-the translation elongation factor-1 alpha (EF-1 alpha) gene and the internal transcribed spacer (ITS) and intergenic spacer (IGS) regions of ribosomal DNA-to compare their accuracy in identifying species of Japanese Armillaria. We studied 49 isolates of eight Armillaria species, A. mellea, A. ostoyae, A.(More)
Relationships among East Asian, North American and European Laetiporus sulphureus s. lat., a cosmopolitan brown rot species complex, were assessed with phylogenetic analyses and incompatibility tests. Three East Asian taxa, Laetiporus cremeiporus sp. nov., Laetiporus montanus and Laetiporus versisporus, are described and illustrated as well as compared with(More)
Trunk rot poses a substantial threat to Sanbu-sugi, one of the most economically important cultivars of Japanese cedar (Cryptomeria japonica). The etiology of this disease, including its main agents, is incompletely known. This trunk rot was attributed to Fomitiporia (Phellinus) hartigii or F. (Phellinus) punctata. Here we phylogenetically analyzed DNA(More)
