Weird spores

The spores either look normal, or weirdly twisted with prominent septa creating a chain-like structure. If the pressure of the cover slip caused the weird appearance, I would expect intermediate forms, in-between “not squashed” and “badly squashed”. Who knows.

Any chance

the mounting medium collapsed those weird spores?
They are kind of beautiful in their own way.
