The genus Castanea (Fagaceae) is widely distributed in the deciduous forests of the Northern Hemisphere. The striking similarity between the floras of eastern Asia and those of eastern North America and the difference in chestnut blight resistance among species has been of interest to botanists for a century. To infer the biogeographical history of the genus, the phylogeny of Castanea was estim...
Neem (Azadirachta indica) seedlings were found infested by the brown burrower bug, Scaptocoris castanea Perty, in December 2009, in the county of Tupaciguara, Minas Gerais state. Symptoms observed varied from leaf yellowing and stem drying, reduction in root size and number to plant death. This is the first report of S. castanea attacking neem plants.
The Asiatic oak weevil, Cyrtepistomus castaneus Roelofs (Coleoptera: Curculionidae), is a nonnative defoliator of trees in the Fagaceae family in the United States but has not been studied on Castanea species in the southern Appalachian Mountains. Planted trees of Castanea dentata (Marsh.) Borkh. (Fagales: Fagaceae), Castanea mollissima Blume (Fagales: Fagaceae), and four hybrid breeding genera...
Species in the genus Castanea Mill. are one of the worthwhile species in the Hyrcanian forest of west Guilan (N Iran) with low region such as Siahmazgi, Ghalerodkhan and Visrod. that do not have good condition by reason of human interfering and disease. They have varying economic importance as nut tree crops, therefore, DNA barcoding technique can be a straightforward method for taxonomic statu...
The genus Ivalia Jacoby, 1887 is recorded from Australia for the first time with descriptions of three new species, Ivalia reidi sp. nov., Ivalia iridescens sp. nov., and Ivalia lescheni sp. nov., from Queensland and New South Wales. A check-list of 66 species of Ivalia and a key to the Australian species are provided. New replacement names proposed are Ivalia samuelsoni nom. nov. for Ivalia be...
Two filamentous fungi with different phenotypes were isolated from crushed healthy spores or perforated dead spores of the arbuscular mycorrhizal fungus (AMF) Scutellospora castanea. Based on comparative sequence analysis of 5.8S ribosomal DNA and internal transcribed spacer fragments, one isolate, obtained from perforated dead spores only, was assigned to the genus Nectria, and the second, obt...

Heterochelamon tessellatum n. sp. and H. castanea n. sp. are described trom the Guangxi Zhuang Autonomous Region, southern China. Heterochelamon tessellatum n. sp. and H. castanea n. sp. are morphologically most similar to H. yangshuoense Türkay & Dai, 1997, and H. guangxiense Türkay & Dai, 1997, respectively. The new species can be differentiated from these allied species by differences in the...
Using a dataset comprising 5.8S rDNA sequences from a wide range of fungi, we show that some sequences reported recently from the arbuscular mycorrhizal (AM) fungus Scutellospora castanea most likely originate from Ascomycetes. Other ITS and 5.8S sequences which were previously reported are confirmed as being clearly of mycorrhizal origin and are variable within one isolate of S. castanea. Howe...
