Fulvifomes xylocarpicola sp. nov. is characterized by the perennial and sessile basidiocarps, woody context without a distinct crust, pores 4–6/mm, a dimitic hyphal system both in the context and t...

Type examinations were conducted for 32 species of polypores described by E.J.H. Corner. The following new combinations are proposed: Antrodiella subligativa, Coriolopsis albobadia, C. suberosifusca, Datronia perstrata, D. sepiicolor, Fomitella malaysiana, Fomitopsis subvinosa, Microporus affinis-microloma, M. subvernicipes, Nigrofomes nigrivineus,...

We present a taxonomic study of ‘group Favolus’ and related species in Polyporus. Phylogenetic analyses of nurLSU and ITS regions revealed that the infrageneric ‘group Favolus’ is divided into two main clades. Fungi within the group share laterally stipitate basidiocarps, with non-crustose stipe surfaces, and are distinguishable by the morphology o...

We reviewed the ecological characteristics of wood-inhabiting fungi in Malaysia in relation to the major threats to these fungi; we also examined the forest uses that would help to conserve them. Although wood-inhabiting fungi do not show high host specificity or preference in many tropical areas, several are specific to Dipterocarpaceae trees in M...

Biogeography of polypores distributed in the Malesian region is reviewed. Some of the species reported from this region are pantropical or paleotropical and widely distributed along the equator. Several species are restricted to lowland areas of Malesia and adjacent regions, and can be classified as Asian or Asian-Oceanian tropical species. Some sp...

Brown root rot disease (BRRD), caused by Phellinus noxius, is an important tree disease in tropical/subtropical areas. To improve chemical control of BRRD and deter emergence of fungicide resistance in P. noxius, this study investigated control efficacies and systemic activities of fungicides with different modes of action. Fourteen fungicides with...

The traditional medicinal fungus, Lingzhi, has long been considered to be Ganoderma lucidum, but was recently described as G. lingzhi based on both morphological and molecular data. Months earlier than this description, the species was identified as G. sichuanense by another research group. A sequenced epitype for G. sichuanense was selected that,...

The order Hymenochaetales of white rot fungi contain some of the most aggressive wood decayers causing tree deaths around the world. Despite their ecological importance and the impact of diseases they cause, little is known about the evolution and transmission patterns of these pathogens.

An unusual mortality of several woody plant species was recently found in the Ogasawara Islands. Here, we show that brown root rot caused by Phellinus noxius was the primary cause of this unusual tree death. Typical symptoms of the disease were confirmed on 41 plant species in 29 plant families. Among them, 23 were novel hosts of P. noxius, includi...

Phellinus noxius is a pathogenic fungus that causes brown root rot disease in a variety of tree species. This fungus is distributed in tropical and sub-tropical regions of Southeast and East Asia, Oceania, Australia, Central America and Africa. In Japan, it was first discovered on Ishigaki Island in Okinawa Prefecture in 1988; since then, it has be...

Trunk rot, caused by Fomitiporia torreyae, is one of the most economically important sap rot diseases on Cryptomeria japonica, especially on a cutting cultivar ‘Sanbu-sugi’. This disease had been reported only from Chiba and Ibaraki prefectures in Japan; however, a similar trunk rot on Japanese cedars was found recently in Kyoto prefecture. We iden...

We describe and illustrate two new species of Boletellus section Boletellus, B. aurocontextus sp. nov. and B. areolatus sp. nov., which are generally assumed to be B. emodensis. In this study, we reconstructed separate molecular phylogenetic trees of section Boletellus using the nucleotide sequences of the internal transcribed spacer (ITS) region o...

Dead wood is an important habitat for forest organisms, and wood decay fungi are the principal agents determining the dead wood properties that influence the communities of organisms inhabiting dead wood. In this study, we investigated the effects of wood decomposer fungi on the communities of myxomycetes and bryophytes inhabiting decayed logs. On...

An archaeological waterlogged polypore was found in the Final Jomon period (circa 2600 years ago) at the Neolithic site of Kitashirakawa in Kyoto, Japan. The fragile polypore was treated with the feather-keratin method that we developed for the preservation of wet organic archaeological materials. The method reinforced the polypore against the coll...

Unlike in temperate regions, few studies have examined the effect of sampling effort on the observed number of wood-decaying polypores in the tropics. We conducted field surveys at Pasoh Forest Reserve and Lambir Hills National Park, two primary lowland dipterocarp forests in Malaysia, to compare the numbers of observed and estimated species for ea...

A taxonomic study of poroid Asian species in the Auriculariales was conducted using phylogenetic and morphological methods. Phylogenetic analyses based on the LSU and ITS regions reveal that Elmerina was a polyphyletic genus. Moreover, E. hexagonoides collected from Malaysia and “E. hexagonoides” from Japan formed two distinct clades within a well-...

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...

Improvement cutting, which decreases tree density by cutting and thinning while leaving logging residues, has been practiced on Okinawa Island since the 1970s and changes not only the vegetation composition but also the amount and composition of woody debris on the forest floor. To quantitatively compare the effect of improvement cutting with the e...

Molecular phylogenies using 1-4 gene regions and information on ecology, morphology and pigment chemistry were used in a partial revision of the agaric family Hygro- phoraceae. The phylogenetically supported genera we recognize here in the Hygrophoraceae based on these and previous analyses are: Acantholichen, Ampulloclitocybe, Arrhenia, Cantharell...

The management of natural tropical production forests is charged to meet with mutually exclusive demands, that is, the production of wood materials and the conservation of biodiversity. One possible way of meeting both demands is to introduce improved management techniques such as reduced-impact logging. The effectiveness of reduced-impact logging...

Mushroom fruiting, the reproduction of fungi, has broad implications for forest health, terrestrial biomass turnover, and global carbon cycle. However, little is known about the difference in phenology and environmental drivers of mushroom fruiting between functional guilds, e.g., ectomycorrhizal (ECM) mutualists and saprotrophs (SAP). There is a r...

This study reports the frequency of decay (stem/butt rot) of Xylocarpus granatum trees at Hat Khanom-Mu Ko Thale Tai National Park, Nakhonsithammarat province, and other locations in Thailand, and the identification of purported causal basidiomycetes based on morphological and molecular analyses. Four survey plots at Hat Khanom-Mu Ko Thale Tai Nati...

Both planted and natural forests provide numerous different habitats for various types of organism. After clear-cutting, differences in the restoration process of forest ecosystems, in terms of vegetation structure and woody debris, will affect the community structure of wood-inhabiting aphyllophoraceous fungi. In this study, we conducted field sur...
