Abstract
Botany, Ahead of Print. We contest the recently reported findings that suggest the presence of female gametangia in the North American range of the invasive macroalga Nitellopsis obtusa (Harrow-Lyle, T.J., Ginn, B.K., Kirkwood, A.E., and Melles, S.J. 2023. First report of female gametangia in the invasive macroalga starry stonewort (Nitellopsis obtusa) in North America. Botany, 101: 61–64. doi:10.1139/cjb-2022-0096). The claims do not clearly show identifying morphology of N. obtusa female gametangia, are inconsistent with known characeaen developmental biology, and do not provide the evidence commensurate with such a claim. More convincing observational data are required. To date, only male thalli of N. obtusa have been confirmed either with herbarium vouchers or clear images. The appearance of female gametangia would have significant implications for the invasion biology of N. obtusa as well as approaches to managing its spread.
我们没有发现北美 Nitellopsis obtusa (Desvaux) J. Groves 中存在雌配子器（卵孢子）的证据。
植物学》，打印前。 最近有报道称，入侵大型藻类星石草（Nitellopsis obtusa）的北美分布区存在雌性配子器（Harrow-Lyle, T.J., Ginn, B.K., Kirkwood, A.E., and Melles, S.J. 2023.北美入侵大型藻类星石草（Nitellopsis obtusa）雌配子器的首次报告。doi:10.1139/cjb-2022-0096）。这些说法没有清楚地显示 N. obtusa 雌配子器的识别形态，与已知的characeaen 发育生物学不一致，也没有提供与这种说法相称的证据。需要更有说服力的观察数据。迄今为止，只有标本馆的凭证或清晰的图像证实了 N. obtusa 的雄蕊。雌配子器的出现将对欧鼠李的入侵生物学以及管理其扩散的方法产生重大影响。
