<正>1 INTRODUCTION Wood-inhabiting fungi from northern China were investigated extensively during last ten years, and the species in the area are relatively well known (Dai 2000; Dai et al. 2006, 2007; Wei et al. 2005;     

Three new species of Inonotus (Basidiomycota, Hymenochaetaceae) from China

Three new species of Inonotus are described and illustrated. Inonotus acutus sp. nov. is characterized by having small, thin basidiocarps with a strongly contracted base, a sharp and undulate pileus margin, ventricose hymenial setae, and ellipsoid, yellowish to yellow-brown, slightly thick-walled basidiospores. Inonotus chrysomarginatus sp. nov. differs in having an annual to perennial growth habit, pileate basidiocarps with a distinctly yellowish buff to golden-yellow margin, distinct setal hyphae and hooked hymenial setae, and broadly ellipsoid to subglobose, pale yellowish, slightly thick-walled and weakly cyanophilous basidiospores. Inonotus rigidus sp. nov. is distinguished by its resupinate and hard rigid basidiocarps, the honey-yellow pore surface, and smaller pores; microscopically, it has ellipsoid, yellowish brown and thick-walled basidiospores, and lacks both setal hyphae and hymenial setae. An identification key to the Chinese species of Inonotus sensu stricto is provided.

Two new setae-lessPhellinus species with large coloured spores (Fungi,Hymenochaetaceae)

Two new species ofPhellinus rimosus complex are described, viz.Phellinus coffeatoporus Kotl. etPouz. from Florida (U.S.A.) characterized by globose spores andPhellinus resinaceus Kotl. etPouz. from Papua-New Guinea and Australia which is distinguished by a very thick and faintly yellowish tinted spore wall.     

Morphological and molecular identification of two new species of Tubulicrinis (Hymenochaetaceae,Hymenochaetales) from southern China

Two new wood-inhabiting fungal species, Tubulicrinis xantha and T. yunnanensis spp. nov., are described based on morphological and molecular characters. Tubulicrinis xantha is characterized by resupinate, furfuraceous basidiomata with buff to yellowish hymenial surface, amyloid lyocystidia and cylindrical to allantoid, hyaline, thin-walled, smooth basidiospores (5.3–6.3 × 1.2–1.6 μm). Tubulicrinis yunnanensis is characterized by pruinose basidiomata with primrose to olivaceous hymenial surface and encrusted lyocystidia and cylindrical, hyaline, thin-walled, smooth basidiospores (4.2–6.2 × 1.2–2 μm). Sequences of ITS and LSU nrRNA gene regions of the studied samples were generated, and phylogenetic analyses were performed with maximum likelihood, maximum parsimony and bayesian inference methods. The phylogenetic analyses based on molecular data of ITS and ITS + nLSU sequences showed that T. xantha grouped with T. martinicensis, and T. yunnanensis grouped with T. glebulosus.

Inonotus tenuicontextus sp. nov. (Hymenochaetaceae) from Guizhou, southwest China with a preliminary discussion on the phylogeny of its kin

Inonotus tenuicontextus collected from Guizhou, southwest China was described and illustrated as a new species based on a combination of phylogenetic and morphological evidence. It is characterized by perennial and effused-reflexed to pileate basidiocarps; duplex and very thin context; a monomitic hyphal system in context; a dimitic hyphal system in trama; and broadly ellipsoid, hyaline and thick-walled basidiospores. Phylogenetically I. tenuicontextus clustered within Inonotus s. s. clade; moreover, it formed a well supported monophyletic subclade with Inonotus baumii, I. linteus, I. lonicericola, I. vaninii and I. weirianus. In morphology I. tenuicontextus distinguishes from I. linteus, also a species with duplex context, by its smaller basidiospores, while its duplex context makes it different from the other four species with homogeneous context. We proposed this subclade as a medicinal group for most of its members with medicinal functions. The phylogeny of the six species in this medicinal group was briefly discussed based on our results. An identification key to them is also provided.     

New and interesting species of Hymenochaetaceae from the Brazilian Amazonia

Coltricia globispora sp. nov. is described as new based on specimens collected in the Parque Natural Municipal de Porto Velho, in the state of Rondônia, Brazilian Amazonia. It is characterized by small pores (7–8 per mm), monomitic hyphal system, and globose, smooth and guttulate basidiospores (5.5–6.6 (?7) μm). Phellinus griseoporus has been found for the first time in Brazil, and Cyclomyces iodinus, P. merrillii, P. membranaceus and P. umbrinellus in the Brazilian Amazonia. Coltricia cinnamomea, P. calcitratus and Phylloporia chrysites are new occurrences to the state Rondônia, while C. hamata and Phylloporia spathulata to the state of Pará. The knowledge about Hymenochaetaceae in the Brazilian Amazonia is briefly discussed, and a key to the neotropical species of Coltricia is provided.     

A new Mantalania species (Rubiaceae) from Madagascar

Mantalania longipedunculata De Block & A.P. Davis, a new species of Rubiaceae (Gardenieae) from Île Sainte Marie, Madagascar, is described, illustrated, and compared with the three other species in the genus. An extinction risk assessment is given, using the categories and criteria of the World Conservation Union (IUCN).  © 2006 The Linnean Society of London, Botanical Journal of the Linnean Society , 2006, 151 , 421–424.     

A new species ofThottea (Aristolochiaceae) from India

Thottea ponmudiana sp. nova from Kerala (India) can readily be distinguished from its closest allyTh. siliquosa and all the other known species of the genus by its yellow flowers with purple eyes, deeply lobed perianth with strongly reflexed margins, uniseriate stamens united in three bundles and strongly 4-angled, green, glabrescent fruits.     

A new species ofLiparis (Orchidaceae) from India

Liparis indiraii spec. nova from India is close toL. alata A. Rich. andL. atropurpurea Lindl.     

A new species ofAdenophora (Campanulaceae) from Korea

Adenophora erecta S. Lee, J. Lee et S. Kim, is described as a new species from an open north-facing mountain slope on the coast of Sukpo-Dong, Ullungdo Is., Kyungsangbukdo, Korea. This species resemblesA. remotiflora Miq., but is well separated by having the leaves compactly arranged along the upper part of the stem, condensed raceme, distinct veins on the corolla and especially shallow dome-shaped epigynous nectar disc.
