A new species of Inonotus (Hymenochaetaceae) from Scandinavia

The new species Inonotus ulmicola belongs to the Inonotus obliquus complex. It is separated by the presence of solitary tramal setae, and by growing on Ulmus , and is reported from Denmark and Sweden. A survey is presented of the species of Inonotus growing in trunk cavities and beneath the bark, and a classification of the setae is proposed.

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 species of Ulota (Orthotrichaceae,Bryopsida) with multicellular spores,from the Hengduan Mountains,Southwestern China

Abstract

Two new species, Ulota yunnanensis and Ulota gigantospora, are described from Yunnan and Sichuan Provinces, China. Both have multicellular spores, a relatively uncommon character in the genus. Differences between the species include growth form and habit, leaf areolation, capsule shape, peristome structure and ornamentation, operculum shape and colour, as well as vaginula and calyptra hairiness. These characters and those discriminating the new species from other ones with similar spore type are discussed and illustrated.     

Two new species of myrmecophytic Tococa (Melastomataceae) with unusually large floral bracts

Two new species ofTococa with large bracts and ant domatia are described.Tococa leticiana has caducous acuminate floral bracts that enclose the young inflorescence and is known only from Leticia, Colombia.Tococa costoides has persistent broadly ovate floral bracts and is known from Amazonas State in Brazil.

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.     

基于形态和分子数据的中国锈迷孔菌属一新种

结合形态学特征和分子序列分析发现采自内蒙古自治区和黑龙江省兴安落叶松树上一新种——蒙古锈迷孔菌,对此种进行了形态描述和特征图示,并讨论了该新种与其近缘种之间的异同。     

Two new species of Phoridae (Diptera) whose larvae associate with large spiders (Araneae: Theraphosidae)

Two new species of Megaselia Rondani, M. dinwrphica Disney and M. praedafura Disney, are described from South America. Their larvae crawl around on the bodies and exuviae of Theraphosidae. Larvae of M. praedafura were observed moving on to the spider's prey while it was engaged in feeding from the same prey.     

Two new DorvNea species (Polychaeta, Dorvilleidae) with obligate asexuaI reproduction

Two new species, Dorvillea bermudensis sp.n. and D. albomaculata sp.n., with obligate asexual reproduction are described. Both are closely related to sexually reproducing members of the same genus. The new species undergo repeated fission of the architomy type, with the rate of regeneration and subsequent production of segments being positively correlated with the energy content of the fragments. Regeneration and reproductive potentials vary between head and tail fragments with tail lineages producing higher rates than head lineages. Both species are very tolerant of starvation which may cause considerable degrowth and initiation of dispersal behavior.     

Two new maastrichtian species ofSerpentipora (Bryozoa)

Two new species are described of the cyclostomatous bryozoan genusSerpentipora Brood.S. germanka is not uncommon in the White Chalk of Northern Europe andS. rugosa occurs in the Upper Maastrichtian of the Netherlands. Fossil species ofSerpentipora have not been reported previously from Europe.     

New species of Hypocreales (Fungi,Ascomycetes)

The new ascomycetes Hypomyces succineus, Podostroma eperuae, and Nectria phialotrichi are proposed. Hypomyces succineus occurs on basidiomata of Pholiota sp. in New York; its anamorph is described as the new species Cladobotryum succineum. Podostroma eperuae occurs on decaying pods of a species of Eperua found in French Guiana and Guyana. Its anamorph is unknown. Nectria phialotrichi occurs on perithecia of Nectria sp. and bark in Guyana; its anamorph is referred to the anamorph genus Onychophora.
