is a wood-destroying parasitic edible mushroom growing on diverse broad-leafed trees in New Zealand and other Pacific areas. Recent molecular systematics of European , a newly delimited Asian phylum and of related species, corroborated the distinction of the chiefly saprobic cultivated edible mushroom from . Here, we show that exhibits a morpho-physiological trait characteristic to its European cousin, i.e., monokaryotic fruiting (basidiome formation without mating). Monokaryotic fruiting structures formed by ICMP 11668-derived monokaryons were categorized into four phenotypes. One of them displays ulcer-like structures previously reported from bracket fungi. Histology of dikaryotic and monokaryotic fruiting structures revealed anatomical commonalities and differences between them, and towards monokaryotic fruiting structures of . Mating experiments with strains representative of each fruiting phenotype identified compatible sibling monokaryons. Given reports on hypothetically monokaryotic basidiome field populations of '', it seems worthwhile to prospectively investigate whether monokaryotic fruiting s.str. occurs in nature. Sampling from such populations including karyotyping, comparative -omics, and competition assays may help to answer this question and provide evidence whether this trait may confer competitive advantages to a species capable of it.
是一种生长在新西兰和其他太平洋地区多种阔叶树上的破坏木材的寄生食用菌。欧洲近期对一种新划定的亚洲门类及其相关物种的分子系统学研究，证实了主要腐生的栽培食用菌与……的区别。在此，我们表明……表现出与其欧洲同类相似的形态生理特征，即单核结实（无需交配形成担子果）。由源自ICMP 11668的单核体形成的单核结实结构被分为四种表型。其中一种表现出先前在多孔菌中报道过的溃疡样结构。双核和单核……结实结构的组织学揭示了它们之间以及与……单核结实结构之间的解剖学共性和差异。对每种结实表型的代表性……菌株进行交配实验，确定了相容的同胞单核体。鉴于有关“……”假设单核担子果野外种群的报道，前瞻性地研究单核结实狭义种是否在自然界中出现似乎是值得的。从这些种群中取样，包括核型分析、比较组学和竞争试验，可能有助于回答这个问题，并提供证据证明这种特征是否可能赋予具有该特征的物种竞争优势。
