新疆小圆孔壳属，锥毛壳属及座坚壳属的分类研究

本文报道了新疆子囊菌小圆孔壳属(Amphisphaerella),锥毛壳属(Coniochaeta)和座坚壳属(Rosellinia)的7个种及1个变种,即:忍冬小圆孔壳(A.xylostei),梭梭锥毛壳(C.haloxylonis),木生锥毛壳(C.ligniaria),粉被锥毛壳(C.pulveracea),毛锥毛壳(C.sordaria),附孢座坚壳(R.aquila),乳头座坚壳(R.thelena)及尖孢座坚壳大孢变种(R.apiculata var.macrospora)。其中,梭梭锥毛壳为新组合种。忍冬小圆孔壳,木生锥毛壳,乳头座坚壳及尖孢座坚壳大孢变种为我国新记录(属)种。这3个属的真菌新疆过去均未报道过,为新疆新记录属。

STUDIES ON THE GENERA AMPHISPHAERELLA,CONIOCHAETA AND ROSELLINIA OF XINJIANG,CHINA

Seven species and one variety in the three genera,Amphisphaerella Coniochaeta and Rosellinia,occurring in Xinjiang,China were treated in this paper.Coniochaeta haloxy- lonis (B.Kravtz.) Z.Q.Yuan & Z.Y.Zhao com.nov.,a new combination based on Rosellonia haloxyli B.Kfaxtz.,is characterized by having oblong cylindrical ascospores with a length/ width ratio of 2.5,lacking setae on perithecium and associating with desert plants.Amphis- phaerella xylostei,Coniochata ligniria,Rosellinia thelena and R.apiculata var.macrospora are recorded for the first time from China. All specimens metioned in this paper are deposited in the Herbarium of Mycology,August 1st Agricultural College (HMAAC),Xinjiang,China.
