摘　　要：本文报道云南省西双版纳的小煤炱科(Meliolaceae)4个新种和1个新变种.它们分别是:桑寄生针壳炱Irenopsis Loranthi Y.x.Hu,八宝树小煤炱Meliola duabangaeY.X.Hu,青藤生小煤炱Meliola illigericola Y.X.Hu et B.Song,大叶藤生小煤炱Meliola tinomsciicola Y.X.Hu et Y.S.Ouyang,红光树生小煤炱细小变种Meliolaknemicola Hansf.var.minor B.Song et Y.S.Ouyang.桑寄生针亮炱的文字描述和显微结构图.模式标本藏于广东省微生物研究所.This paper reported four new species and one new variety of Meliolaceae which are collected by the authors from Xishuanbanna of Yunnan. The new species are Irenopsis loranthi Y. X. Hu parasitic on Loranthus pentapetalus Roxb. (Loranthaceae). This species is close to Meliola loranthi Gaill on loranthus sp. from Borneo, but differs from it in lacking mycelial setae and in having perithecial setae. It is only one species of Irenopsis parasitic on Loranthaceae. Meliola duabangae Y. X. Hu on Duabangae grandiflora (Roxb. et DC.) Walp. (Sonneratiaceae), Sonneratiaceae is a new host family Meliolaceae. Meliola illigericola Y. X. Hu et B. Song on Illigera celebica Miq. (Hernandiaceae). This new species mixed with M. illigerae Stev. et Rold ex Hansf., but mainly differs from it in having smaller capitate hyphopodia, head cells ovoid and 5% oppositate hyphopodia. Meliola tinomisciicola Y. X. Hu et Y. S. Ouyang is close to M. cissampeli var. tiliacorae Hansf. et Deight., but differs from it in having 30%～40% opposite capitate hyphopodia, head cells globose, ovoid and mycelial setae acute. The new varity is Meliola knemicola Hansf. var. minor B. Song et Y. S. Ouyang, it differs from the M. knemicola Hansf. in having smaller capite hyphopodia, ascospores and mycelial setae acute. All species are deposited in Guangdong Institute of Microbiology Guangzhou.
