Tests of species concepts of the small,white, European group of <Emphasis Type="Italic">Tuber</Emphasis> spp. based on morphology and rDNA ITS sequences with special reference to <Emphasis Type="Italic">Tuber rapaeodorum</Emphasis>

Several taxonomic problems arise in the group of small, white European truffles, probably due to the over-emphasized significance of certain morphological features of ascomata. The distinction between Tuber rapaeodorum Tul. & C. Tul. and Tuber borchii Vittad. and Tuber puberulum Berk. & Broome has not been accepted in several recent studies. Furthermore, the existence of T. rapaeodorum been questioned in some recent synopses of the genus. We conducted microscopic and ITS sequence investigations of 31 herbarium specimens. Using morphological features such as peridium structure, form and size of spores and dermatocystidia and spore numbers per ascus, we could distinguish T. borchii, T. foetidum Vittad., T. maculatum Vittad., Tuber puberulum, and T. rapaeodorum. Analysis of whole ITS sequences showed sharp differences among the morphologically separated groups. Neighbour-joining and parsimony methods produced highly supported branches and confirmed the identity of these species.     

Pink root rot,a revised name of brown root rot of gentian,and the causal fungi,Pyrenochaeta gentianicola sp. nov. andP. terrestris in Japan

Cultivated gentian (Gentiana scabra var.buergeri) has been seriously damaged by pink root rot since the 1970s. Diseased plants finally collapse after wilting and stunting. More than 40 fungal genera were found to be associated with roots of mature and immature diseased plants or seeds. Among these fungi,Pyrenochaeta gentianicola sp. nov. andP. terrestris were almost always associated with the diseased plants. Their morphologies and temperature responses were compared, and their pathogenicity was also demonstrated by artificial inoculation tests.Part of this work was conducted at the National Institute of Agricultural Sciences (presently National Institute of Agro-Environmental Sciences), Tsukuba S.C., Ibaraki 305, Japan by T. Watanabe.

苦苣苔科吊石苣苔属一新异名

2017年，印度学者Joe等基于采自中国藏东南地区的植物标本，发表了合萼吊石苣苔的一新变种Lysionotus gamosepalus W. T. Wang var.biflorus A. Joe, Hareesh&M. Sabu,并且认为该新变种与原变种的主要区分特征包括叶缘稍具锯齿、每个腋生花序仅有2朵花、花冠被毛、具2枚卷曲的退化雄蕊。然而，近年来，笔者基于查阅大量标本和野外考察工作，认为所谓变种的形态特征是在合萼吊石苣苔(Lysionotus gamosepalus W. T. Wang)的变异范围之内，加之分布区完全重叠，生长环境类似，物候期一致，不宜作为变种等级处理。故在此将该变种处理为合萼吊石苣苔的异名。

Typification,taxonomy, and worldwide distribution of Braunia secunda (Hook.) Bruch & Schimp. (Hedwigiaceae)

Diagnosis and illustrations are given for Braunia secunda (Hook.) Bruch & Schimp., and a Humboldt and Bonpland specimen (BM) is selected as the lectotype. Also a collection by Arséne (BM) is designated as the lectotype for B. secunda var. crassiretis Thér. This variety is retained as synonym of B. secunda. The species concept of B. secunda is revised and a provisional key is provided to help in the identification of 23 species of Braunia, based on examination of herbarium specimens worldwide. About half of specimens from Mexico actually represent another species, B. andrieuxii Lorentz. All material examined from India, previously identified as B. secunda belongs to B. macropelma (Müll.Hal.) A.Jaeger, whereas collections from Africa are actually B. rupestris (Mitt.) A.Jaeger, B. entodonticarpa Müll.Hal., or B. diaphana (Müll.Hal.) A.Jaeger. These and other species should no longer be considered synonyms of B. secunda. The worldwide distribution of the species is documented for the United States, Mexico, Guatemala, Dominican Republic, Haiti, Venezuela, and Bolivia.
