sporule

The orange protoplasm passes along the colourless tubes to the terminal sporule at the end of its vegetation.

This sporule of the second generation ordinarily detaches itself from its support before germinating.

At the same time a terminal sporule generally appears on the threads.

I wonder what sort of floating sporule carries the infection—reaching the brain by the nose, I fancy.

An invisible sporule in the air may do it, or a lesion no bigger than a pin's point.
