Abstract

Six new species and two new records of Crepidotus are described from Thailand. Macroscopic and microscopic descriptions with photoplates, as well as a multigene phylogeny, are provided. Crepidotus chiangraiensis sp. nov. is recognized as densely velutinous with white hairs longer near the point of attachment, not striate margin, and not hygrophanous. Crepidotus- flavocarpus sp. nov. is recognized by yellow to yellowish pileus basidiomata, margin discolorous paler yellow, densely velutinous with white hairs near the point of attachment, smooth globose basidiospores, and inverse hymenophoral trama. Crepidotus thailandicus sp. nov. is recognized by a tomentose surface with white hair when primordial to early stages and then disappearing with age when mature present long translucent-striate reward to the point of attachment becoming fade away at central. Crepidotus roseocarpus sp. nov. is recognized by large basidiomata, pileus, lamellae, and context are pastel pink, concolorous darker pink at the margin, hymenophoral trama convergent, with cylindrical terminal elements. Crepidotus-ungulatus sp. nov. is recognized by ungulate basidiomata, brownish orange near the point of attachment, the basidiomata color changed to light brown in three hours, and the margin is concolorous to the surface of the pileus. Crepidotus viscidus sp. nov. is recognized by white semicircular pileus, translucent-striate with gray to dark grey margin, lamellae pale orange to orange-white, glutinous context, smooth basidiospore and hymenophoral trama present regular form. Crepidotus lateralipes and C. striatus are reported as new records to Thailand.

新增 Crepidotus 种类（担子菌纲）：泰国的六个新种和两个新记录

该研究描述了泰国的六个新种和两个新记录。文章提供了宏观和微观描述，并附有图片以及多基因系统发育。Crepidotus chiangraiensis sp. nov.被确认为茸毛密布，附着点附近的白毛较长，边缘无条纹，无嗜水性。Crepidotus- flavocarpus sp. nov.的特征是黄色至淡黄色的绒毛基部，边缘褪色呈浅黄色，密被茸毛，附着点附近有白色绒毛，基部有光滑的球状孢子，以及反向的膜柄。Crepidotus thailandicus sp. nov.的识别特征是：原始至早期阶段表面被绒毛，有白色绒毛，成熟后随着年龄的增长绒毛消失，附着点处有长长的半透明条纹状奖励，中心逐渐消失。Crepidotus roseocarpus sp. nov.的特征是基部基瘤较大，绒毛、薄片和上下文呈粉红色，边缘呈深粉红色的同色系，处女膜瓣收敛，顶端呈圆柱形。Crepidotus-ungulatus sp. nov.的识别特征是：基原体为单胃，靠近附着点处呈棕橙色，基原体颜色在三小时内变为浅棕色，边缘与绒毛表面同色。Crepidotus viscidus sp.nov.的特征是：白色半圆形绒毛，半透明条纹状，边缘灰色至深灰色，薄片淡橙色至橙白色，有糯性背景，基生孢子光滑，菌膜呈规则形状。据报道，Crepidotus lateralipes 和 C. striatus 是泰国的新记录。

期刊介绍： Phytotaxa is a peer-reviewed, international journal for rapid publication of high quality papers on any aspect of systematic and taxonomic botany, with a preference for large taxonomic works such as monographs, floras, revisions and evolutionary studies and descriptions of new taxa. Phytotaxa covers all groups covered by the International Code of Nomenclature foralgae, fungi, and plants ICNafp (fungi, lichens, algae, diatoms, mosses, liverworts, hornworts, and vascular plants), both living and fossil. Phytotaxa was founded in 2009 as botanical sister journal to Zootaxa. It has a large editorial board, who are running this journal on a voluntary basis, and it is published by Magnolia Press (Auckland , New Zealand). It is also indexed by SCIE, JCR and Biosis. All types of taxonomic, floristic and phytogeographic papers are considered, including theoretical papers and methodology, systematics and phylogeny, monographs, revisions and reviews, catalogues, biographies and bibliographies, history of botanical explorations, identification guides, floras, analyses of characters, phylogenetic studies and phytogeography, descriptions of taxa, typification and nomenclatural papers. Monographs and other long manuscripts (of 60 printed pages or more) can be published as books, which will receive an ISBN number as well as being part of the Phytotaxa series.
