Abstract

ABSTRACT Three novel species of Russula Pers. subg. Compactae (Fr.) Bon from southern China are described with morphological evidence and phylogenetic analyses based on ITS and the concatenated partial LSU, mtSSU, rpb1, rpb2 and tef1 gene sequences. All three species possess sparse and broad lamellae. Russula latolamellata Y.Song & L.H.Qiu, sp. nov., is characterized by its cracking, black-tan pileus, scarlet-turning context on bruising and absence of pileocystidia and caulocystidia. Russula nigrocarpa S.Y.Zhou, Y.Song & L.H.Qiu, sp. nov., can be distinguished by its off-white lamellae, small basidiospores, hymenial cystidia and pileocystidia of various forms, often with forked apices and by its gelatinous pileipellis. Russula ochrobrunnea S.Y.Zhou, Y.Song & L.H.Qiu, sp. nov., is characterized by its cracking, grayish brown pileus with striate margin, light-brown lamellae whose edges turn dark-brown when mature, small basidiospores and slightly flexuous ormoniliform hymenial cystidia. Their detailed morphological features and phylogenetic positions are discussed and compared among closely related species.

标题紫果属三新种。Subg。华南鼎湖山生物圈保护区的柏属植物

摘要/ ABSTRACT摘要:树菇属三新种。subg。基于ITS和部分LSU、mtSSU、rpb1、rpb2和tef1基因序列的串联，对中国南方的Compactae (Fr.) Bon进行了形态证据和系统发育分析。这三种都有稀疏而宽阔的片层。Russula latolamellata Y.Song & L.H.Qiu, sp. nov.，其特征是其开裂，黑棕色的毛，瘀伤时变红的背景，以及没有毛囊和根囊。乌苏娜·黑卡帕(Russula nigrocarpa)，周素英，宋玉英，邱立红，等，可通过其灰白色的片层，小的担子孢子，各种形式的膜囊胞和毛囊胞，通常具有分叉的顶端和凝胶状的绒毛来区分。黄褐褐孢，周顺英，宋勇，邱立红，等。其特征为裂孔状，菌毛呈灰褐色，边缘有条纹，浅棕色，成熟后边缘变成深褐色，孢子小，包膜囊体呈球状，微弯曲。讨论了它们的详细形态特征和系统发育位置，并在密切相关的物种中进行了比较。

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).
