Abstract

ABSTRACT During surveys in the Brazilian Amazon, Atlantic Forest and Caatinga, several species of poroid Hymenochaetaceae were collected. Of the collected specimens, ITS and LSU sequences were generated and phylogenetic analyses performed. From morphological and phylogenetic inferences, Sclerotus Xavier de Lima, gen. nov. is described based on collections of Phellinus extensus, while Inonotus parvisetus V.R.T. Oliveira, Xavier de Lima & Gibertoni, sp. nov., Tropicoporus flabellatus V.R.T. Oliveira, J.R.C. Oliveira-Filho, Xavier de Lima & Gibertoni, sp. nov and T. nullisetus Xavier de Lima, V.R.T. Oliveira & Gibertoni, sp. nov. are described as new species. Sclerotus gen. nov. is characterized by the strongly ventricose hymenial setae and the black line that is exposed as a dark crust. Inonotus parvisetum can be differentiated from similar species of the genus by the smaller tramal setae. Tropicoporus flabellatus sp. nov. produces the thinnest basidiomata in the genus, and does not develop a dark crust in the pileus surface, while in T. nullisetus sp. nov. hymenial setae is absent. The other specimens clustered within I. micantissimus (Rick) Rajchemb., I. rickii (Pat.) Reid, T. linteus (Berk. & M.A.Curtis) L.W.Zhou & Y.C.Dai, T. stratificans G.Coelho & Yurchenko and T. tropicalis (M.J.Larsen & Lombard) L.W.Zhou & Y.C.Dai. Here T. stratificans is recorded for the first time outside the type locality. Illustrations of the species and keys for Inonotus sensu lato are provided.

文章标题巴西膜毛藻科Inonotus s.l.的分类及系统发育分析

摘要在巴西亚马逊河流域、大西洋森林和卡廷加等地的调查中，收集到几种多孔膜毛科植物。采集标本，生成ITS和LSU序列，并进行系统发育分析。从形态学和系统发育的推断来看，Sclerotus Xavier de Lima, gen11 .是基于Phellinus extensus的资料描述的，Inonotus parvisetus V.R.T. Oliveira, Xavier de Lima & Gibertoni, nov, Tropicoporus flabellatus V.R.T. Oliveira- filho, Xavier de Lima & Gibertoni, nov和T. nullisetus Xavier de Lima, V.R.T. Oliveira & Gibertoni, nov被描述为新种。巩膜刚毛呈强烈的心室状，黑线呈黑色外壳。小野藜可以通过较小的绒毛与同类区分开来。flabellatus sp. 11 .的担子毛是属中最薄的，并且在毛表面不形成深色的外壳，而在T. nullisetus sp. 11 .中没有膜层刚毛。其他标本聚在I. micantissimus (Rick) Rajchemb中。I. rickii(帕特)里德，T. linteus(伯克)。周立伟和戴永昌，T. stratiologist G.Coelho和Yurchenko, T. tropical alis (M.J.Larsen和Lombard)周立伟和戴永昌。这是第一次在模式地点以外记录到层状石。提供了Inonotus sensu lato的种类图和分类键。

期刊介绍： Cryptogamie is divided into three sections, each published as an individual publication: Cryptogamie, Bryologie, Cryptogamie, Algologie and Cryptogamie, Mycologie. Cryptogamie is a French journal of international scope publishing in several European languages. It accepts original papers and review articles on the systematics, biology and ecology of all cryptogams (algae; bryophytes; fungi and lichens, respectively).
