Bolete species known from china

Abstract: 397 species or varieties of 28 genera of Chinese tubular and lamellate boletes so far known by the authors are listed and their distributions are indicated They are offered in the hope that the information will be helpful to better understanding the Chinese bolete mycoflora and diversity, and the lists will be integrated by the users of insight

Prized edible Asian mushrooms: ecology, conservation and sustainability

Abstract: Mushrooms can be found in forests worldwide and have long been exploited as resources in developed economies because of their important agro-industrial, medicinal and commercial uses. For less developed countries, such as those within the Greater Mekong Subregion, wild harvesting and mushroom cultivation provides a much-needed alternative source of income for rural households. However, this has led to over-harvesting and ultimately environmental degradation in certain areas, thus management guidelines allowing for a more sustained approach to the use of wild mushrooms is required. This article addresses a selection of the most popular and highly sought after edible mushrooms from Greater Mekong Subregion: Astraeus hygrometricus, Boletus edulis, Morchella conica, Ophiocordyceps sinensis, Phlebopus portentosus, Pleurotus giganteus, Termitomyces eurhizus, Thelephora ganbajun, Tricholoma matsuake, and Tuber indicum in terms of value, ecology and conservation. The greatest threat to these and many other mushroom species is that of habitat loss and over-harvesting of wild stocks, thus, by creating awareness of these issues we wish to enable a more sustainable use of these natural products. Thus our paper provides baseline data for these fungi so that future monitoring can establish the effects of continued harvesting on mushroom populations and the related host species.

Zangia , a new genus of Boletaceae supported by molecular and morphological evidence

Abstract: A new distinct genus of Boletales, Zangia, with phenotypic similarities to the genus Tylopilus, is proposed based on molecular and morphological data. The monophyly of Zangia was highly supported using two nuclear and three mitochondrial genes based on Maximum Parsimony, Maximum Likelihood and Bayesian analyses. Morphologically, Zangia is distinguished from other boletoid lineages by its combination of rugose pileus, pinkish to pink hymenophore, pink to pinkish brown spore deposit, pink scabrous squamules on the stipe, chrome yellow to golden yellow stipe base, chrome yellow to golden yellow mycelia on the base of the stipe, ixohyphoepithelium pileipellis, glabrous spores and bluish colour changes in the stipe in some species. Geographically, Zangia is currently only known from southern, southeastern and southwestern China under forests dominated by Fagaceae mixed with Pinaceae. Six species, including 4 new ones and 2 new combinations, are fully documented with taxonomic descriptions and illustrations. A key to the species in Zangia is provided. It is suggested that some of the species might have started diverging from each other relatively recently with the uplifts of the eastern Himalayas and Hengduan Mountains, and both the mycorrhizal host specificity or preference and geographic separation could contribute to their ongoing divergence.

Corneroboletus, a new genus to accommodate the southeastern Asian Boletus indecorus

Abstract: Corneroboletus was erected in the Boletaceae to accommodate Boletus indecorus originally described from southeastern Asia. The mucilaginous surface of the basidioma, the ixohyphoepithelium pileipellis and the irregularly warty to irregularly bacillate ornamentation of basidiospores distinguish this fungus from other described species in Boletaceae. Phylogenetic placement of this fungus was investigated further with molecular data including LSU rRNA and concatenated alignment of nrLSU, 5.8S rRNA and rpb2 genes, and an independent lineage among existing genera of Boletaceae was suggested by our phylogenetic results. Consequently a description, illustrations and a comparison of Corneroboletus with allied taxa are presented.

Porcini mushrooms (Boletus sect. Boletus) from China

Abstract: Porcini mushrooms (Boletus sect. Boletus) have both economic and ecological importance. Recent molecular phylogenetic study has uncovered rich species diversity of this group of fungi from China. In this study, the Chinese porcini were characterized by both morphological and molecular phylogenetic evidence. 15 species were recognized, including nine new species, namely B. botryoides, B. fagacicola, B. griseiceps, B. monilifer, B. sinoedulis, B. subviolaceofuscus, B. tylopilopsis, B. umbrinipileus and B. viscidiceps. Three previously described species, viz. B. bainiugan, B. meiweiniuganjun and B. shiyong, were revised, and B. meiweiniuganjun is treated as a synonym of B. bainiugan. A key to the Chinese porcini mushrooms was provided.

Three new species of Boletaceae from the Heishiding Nature Reserve in Guangdong Province, China

Abstract: Based on morphological evidence and DNA sequencing, we propose three new species of the basidiomycete family Boletaceae, namely Aureoboletus venustus, Leccinellum onyx, and Pulveroboletus sinensis. The species were collected from the Heishiding Nature Reserve in Guangdong Province, China. The descriptions are illustrated by photographs and line drawings, and comparisons were made with related species. Morphologically, A. venustus is characterized by its mucilaginous pileus with red to reddish orange color, a vivid yellow hymenophore surface, and small ellipsoid basidiospores (7) 7.5–10.5 (12) × 5–6 (7) μm in size. Leccinellum onyx is characterized by its slightly areolating pileus with grayish orange to brownish orange color, a grayish brown to light grayish orange hymenophore surface, short yellowish white tubes, a yellowish white to brownish gray stipe covered with dark brown warts, and small ellipsoid basidiospores with a size of (8) 9–11 (12) × (4) 5–6 μm. Its nucleotide sequence of the internal transcribed spacer (ITS) region is particularly long (1080 bp) in comparison to related species. Pulveroboletus sinensis is characterized by its yellow to vivid yellow pulverulent pileus covered with deep orange to brownish orange conico-pyramidal scales, an appendiculate margin, greenish yellow tubes easily becoming cyanescent upon bruising, a yellow to vivid yellow stipe covered with yellow to brownish orange conico-floccose scales, and small smooth ellipsoid basidiospores with a size of (6) 6.5–8.5 (11) × (4.5) 5–6 (6.5) μm. Phylogenetic analysis of nucleotide sequences of the ITS region and the nuclear large subunit ribosomal RNA gene (nrLSU) provided further evidence that the described mushrooms represent new species.
