Abstract

Serendipita is a prominent fungal genus associated with orchids. In this study, a new species of orchid mycorrhizal fungus, Serendipita officinale, is described and thoroughly studied using morphological and molecular approaches. The fungus was isolated from naturally occurring protocorms of Dendrobium officinale in Chongqing Province, China. S. officinale has been observed to actively promote the germination of seeds and facilitate the seedling development of D. officinale, forming typical mycorrhizal pelotons within protocorm cells. This species is characterized by its characteristics on PDA medium, including the presence of abundant villiform and felty aerial mycelium, uninucleate hyphal cells, and the highest growth rate in terms of colony diameter (78 mm diam. in 2 weeks). Furthermore, analyses of ITS rDNA and LSU sequences also provide additional support for the novelty of this new plant symbiont.

Serendipita officinale sp.

Serendipita 是一种与兰花相关的重要真菌属。本研究描述了兰花菌根真菌的一个新种 Serendipita officinale，并利用形态学和分子方法对其进行了深入研究。该真菌是从中国重庆市自然生长的 officinale 铁皮石斛原球茎中分离出来的。据观察，S. officinale 能积极促进种子萌发，并能在原球茎细胞内形成典型的菌根球团，促进 officinale 的幼苗发育。该菌种在 PDA 培养基上的特征包括存在丰富的长绒毛状和绒毛状气生菌丝、无核的菌丝细胞以及菌落直径最大的生长速度（2 周内直径达 78 毫米）。此外，ITS rDNA 和 LSU 序列分析也为这种新型植物共生体的新颖性提供了更多支持。

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.
