    Hydnangium echinulatum, described originally from a single specimen collected in Malaysia, has been recollected, and based on morphological and molecular characters is recognized as representing a new gasteroid genus of boletes with affinities to the Boletineae, herein named Durianella. Diagnostic features include an epigeous, ovoid, pyramidal-warted, durian fruit-like basidiome with gelatinized glebal locules and a columella that turns indigo blue upon exposure, and subglobose basidiospores with long, curved, thin-walled and collapsible spines. A redescription, phylogenetic analysis and comparison with allied taxa are presented.

    Hydnum is a fungal genus proposed by Linnaeus in the early time of modern taxonomy. It contains several ectomycorrhizal species which are commonly consumed worldwide. However, Hydnum is one of the most understudied fungal genera, especially from a molecular phylogenetic view. In this study, we extensively gathered specimens of Hydnum from Asia, Europe, America and Australasia, and analyzed them by using sequences of four gene fragments (ITS, nrLSU, tef1α and rpb1). Our phylogenetic analyses recognized at least 31 phylogenetic species within Hydnum, 15 of which were reported for the first time. Most Australasian species were recognized as strongly divergent old relics, but recent migration between Australasia and the Northern Hemisphere was also detected. Within the Northern Hemisphere, frequent historical biota exchanges between the Old World and the New World via both the North Atlantic Land Bridge and the Bering Land Bridge could be elucidated. Our study also revealed that most Hydnum species found in subalpine areas of the Hengduan Mountains in southwestern China occur in northeastern/northern China and Europe, indicating that the composition of the mycobiota in the Hengduan Mountains reigion is more complicated than what we have known before.

    Three new and one previously described species of Physalacria (Physalacriaceae, Agaricales) are reported from China. Specimens of two additional species described from Malaysia and North America were studied for comparison. Placements of these species were corroborated based on morphological observations and molecular evidence from partial sequences of the nuc rDNA internal transcribed spacer regions (ITS) and the 28S D1-D3 region, and genes for translation elongation factor 1-α (tef1α) and the second largest subunit of RNA polymerase II (rpb2). These new species of Physalacria distributed in subtropical China were found on rotten wood of broadleaf trees or bamboo and possess stipitate-capitate basidiomata with four-spored basidia, clamp connections and smooth, inamyloid basidiospores. To facilitate studies of the genus in Asia, a key is provided for all Physalacria species reported from this region.

    Three new species and one new variety of bioluminescent Mycena collected from Peninsular Malaysia are described herein. All new species belong to Mycena sect. Calodontes in what is known as the Mycena pura complex. Comprehensive descriptions, photographs, illustrations and comparisons with phenetically similar species are provided. Molecular sequences data from the nuclear internal transcribed spacers (ITS-1 and ITS-2, including the 5.8S rRNA) were used to infer relationships within sect. Calodontes. Axenic cultures were obtained to provide data on culture morphology. This is the first published photographic documentation of bioluminescent basidiomes of members of Mycena sect. Calodontes. Also, this addition brings the total known bioluminescent fungi to 77 species.

    Mycena illuminans Henn. is described and re-evaluated based on recently collected material from peninsular Malaysia, providing comprehensive descriptions, illustrations and photographs. In addition to morphological data, axenic monokaryon and dikaryon cultures were established to provide data on culture morphology and the mating system of the species. Molecular sequences data from the nuclear large subunit (LSU) gene also are presented, confirming that M. illuminans is not a synonym of Mycena chlorophos.
