The mating systems operating in seven species of Marasmius collected recently in northern Thailand were determined. Marasmius cremeus belonging to sect. Sicci subsect. Siccini ser. Leonini, and Marasmius straminiceps belonging to sect. Marasmius subsect. Sicciformes are described as new species. Five members of sect. Marasmius were tetrapolar (bifactorial), viz. M. apatelius, M. guyanensis, M. nigrobrunneus, M. ruforotula, and M. straminiceps. Two members of sect. Sicci were bipolar (unifactorial), viz., M. corneri (syn. M. incarnatus) and M. cremeus. Our data support the hypothesis that the mating system is consistent within infrageneric taxa. The seven species that are herein described, illustrated, and compared with phenetically similar species represent the first reports for this genus in Thailand.
我们确定了最近在泰国北部采集的七种小皮伞属物种的交配系统。属于丝盖伞组干丝盖伞亚组淡黄丝盖伞系的淡黄小皮伞和属于小皮伞组丝盖伞形亚组的草黄小皮伞被描述为新物种。小皮伞组的五个成员是四极性的(双因子的),即阿氏小皮伞、圭亚那小皮伞、黑褐小皮伞、红棕小皮伞和草黄小皮伞。丝盖伞组的两个成员是双极性的(单因子的),即科氏小皮伞(同义名肉色小皮伞)和淡黄小皮伞。我们的数据支持这样一种假设,即交配系统在亚属分类群内是一致的。本文描述、图示并与形态相似物种进行比较的这七个物种代表了该属在泰国的首次报道。
