It’s entirely plausible she didn’t, even though she found what she was looking for. You’ve really gotta catch inkcaps early in their life cycle, before they start to deliquesce. Otherwise they’re cool to look at but not really good for eating.

But also even if she did pick them, it would not have harmed the fungus in any way. Picking a mushroom is no more harmful to the organism than picking a fruit from a tree is. So long as you use a permeable container like a basket or mesh bag to carry them, you’re actually doing the fungus a favour by spreading its spores. It annoys me to no end when uneducated people assume that picking mushrooms is doing damage.
