Taxonomic reevaluation on (, ) and reclassification of species based on phylogenetic and type studies.

We reevaluated the species belonging to the genus that were collected from Japan and Malaysia based phylogenetic analyses and morphological investigations. We found that is distinct from . species with setal hyphae include , , , and .

Notes on section in Hainan Island, China.

Hainan is the second largest island in China with the most extensive and well-preserved tropical forests and is also the largest island of the Indo Burma Biodiversity Hotspot. It provides conservation for the unique ecosystem of the island. Recent studies have shown that there are diverse fungal species in Hainan.

in the Malay Peninsula: Masquerading within .

In 1994 Corner published five new species within the genus , all having been collected on the Malay Peninsula between 1929 and 1930. Three of these species belong to the genus and with their vinaceous colored lamellae and spore print, when fresh, they belong to H. sect.

Notes on Amanita section Caesareae from Malaysia.

Some Amanita specimens collected from Malaysia are critically investigated by morphological examination and molecular analysis of two gene fragments, the nuc rDNA partial 28S (28S) gene and the internal transcriber spacer (ITS1-5.8S-ITS2 = ITS) regions. Six phylogenetic species of Amanita section Caesareae are recognized among the studied collections.

Taxonomy and phylogenetic position of Fomitiporia torreyae, a causal agent of trunk rot on Sanbu-sugi, a cultivar of Japanese cedar (Cryptomeria japonica) in Japan.

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.

Two species of Strobilomyces (Boletaceae, Boletales), S. seminudus and S. hongoi sp. nov. from Japan.

We describe and illustrate two Strobilomyces species, S. seminudus and S. hongoi sp.

Nitrogen nutrition and isotopic discrimination in tropical ectomycorrhizal fungi.

It is known that many ectomycorrhizal (EcM) fungi are able to utilise complex organic sources of nitrogen. Two hypotheses were tested using isolates of tropical EcM fungi grown in vitro: (i) EcM fungi isolated from mineral soils of tropical rain forests are less able to utilise organic sources of nitrogen than mineral sources; and (ii) nitrogen isotope discrimination patterns follow those of the nitrogen source utilised. Pisolithus albus and Tomentella sp.
