Solved ID please for a corm I’m finding with ground elder

I’m currently hand weeding an area under 2 Douglas fir trees, as it has a heavy GE infestation. I’m finding a lot of dark red corms and really don’t know if these should be left be or weeded out too.
Any thoughts what they are? I’m getting no luck with Google, it thinks it’s a chrysalis.

 

The one in the first picture looks like a chrysalis to me and the ones in the other picture appear to be covered in mould.

 

I think they are beetle pupae. possibly chafer beetle , stag beetle or similar. Can you give a scale to help identity?


Edit.
In the light of re-submitted evidence, I withdraw from this discussion!

 

No, surely not, they snap easily.
the first pic is a washed one. They second is how they appear in the ground covered in soil.

I’ll get more pics.

 

More pics.

 

Could they be tubers from Celandine?

 

No, only because I know what they look like. These are bigger, and don’t really hang in bunches like celandine.

 

I thought it was some sort of oxalis.

 

Wouldn't they be in active growth now.

 

Just googled winter aconite and got this picture.

 

That does seem a very likely plant to be in this position, and a good match for what I am seeing.
If I google them for sale, they are more like round blobs, but perhaps they are desiccated when sold.
I feel more confident leaving them be and I’ll look forward to seeing them next year.
Thanks.
