摘要

与其他已知真菌相比，炮弹菌（Sphaerobolus）物种利用一种独特的扣压机制将孢子发射到更远的距离。在这里，我们通过使用高速视频捕捉发射过程、测量排出孢子的内杯产生的力，以及建立孢子排出的力和速度与其轨迹之间关系的模型，提供了有关孢子排出生物力学的新信息。相关计算显示，释放相同数量的孢子时，成片的炮弹菌所消耗的能量是单个带刺蘑菇的80倍。与传统蘑菇释放孢子的巨大损失相比，炮弹菌孢子囊中孢子的损耗相对较低，这可能抵消了这种昂贵机制的演变。

Mechanics of the artillery fungus

Species of artillery fungus, Sphaerobolus, use a unique, snap-through buckling mechanism to discharge their spores over a longer distance than any other known fungi. Here, we provide new information on biomechanics of glebal discharge by capturing the launch using high-speed video, measuring the force generated by the inner cup that expels the gleba, and modeling the relationship between the force and speed of the gleba to its trajectory. Associated calculations reveal that patches of the artillery fungus consume 80 times more energy than an individual gilled mushroom to release the same number of spores. The evolution of this costly mechanism may be counterbalanced by the relatively low wastage of spores carried in its sporangia compared with the greater losses of spores released from conventional mushrooms.
