Abstract:
A new myxomycete species, Arcyria similaris, was reported herein. The specimens were found and collected in the field on dead bark from Jingangtai National Geopark in Henan Province of China. This species has distinct and unique morphological characteristics, including dark grayish olive sporothecae that fade to smoke gray with age, shallow saucer-shaped cups with marked reticulations and thick papillae on the inner surface, a netted capillitium with many bulges, uniformly marked with low, dense, and irregular reticulations, and spores (8.0-)9.3-10.1(-10.9) μm in diameter, marked with sparse small warts and grouped prominent warts. Apart from a comprehensive morphological study, partial sequences of the nuclear 18S rDNA and elongation factor-1 alpha (EF-1α) genes were also provided in this study. This new species was described and illustrated morphologically. The specimens are deposited in the Herbarium of Fungi of Nanjing Normal University (HFNNU).
摘要:
一种新的粘菌,类似的Arcyria,在此报告。这些标本是在中国河南省金刚台国家地质公园的死树皮上发现和收集的。该物种具有独特而独特的形态特征,包括深灰色橄榄孢子囊,随着年龄的增长逐渐变灰,浅盘形杯,内表面有明显的网状和厚的乳头,有许多凸起的网状毛细血管,统一标记为低,密集,和不规则的网状结构,孢子直径(8.0-)9.3-10.1(-10.9)μm,标有稀疏的小疣和成组的突出疣。除了全面的形态学研究,本研究还提供了核18SrDNA和延伸因子1α(EF-1α)基因的部分序列。对这一新物种进行了形态学描述和说明。标本保存在南京师范大学真菌标本室(HFNNU)。
