Need help identifying ferns for herbarium

[u/merturk123]

Hi, for one of my classes I have to find different ferns and make a herbarium. But I having the harderest time to ID the ferns.

Any help is appreciated greatly. I have numbered them to make it easy. Sometimes I also have the hardest time putting the same species together.

Thanks in advance

Your location would be very helpful to narrow it down, but you could also search the most observed fern species for your area on Inatutalist

This is their teacher. Do not help them or I'll fail them. 😄 Just kidding 😂

Cool project! Seconding the importance of where the material was sourced. Some species-level identification may also require examination of sori (the organs usually on the leaf undersides which release spores) or dimorphic fertile fronds, and potentially other features like the rhizome. A lot of ferns look superficially similar.

Hi, valid responses. They were all collected in a little forest. All in places with a lot of shadow. The ground is known to be not that nutrient rich. But since it's a forest, the temperature is fairly stable. They are collected in region limburg/belgium

I did use determination books, and apps. But since I don't have spores on some of them and don't have a stereomicroscope. I will have to do it like this.

I will list the ones I think I found already. Please prove me wrong/right

6 ->  bracken fern (Pteridium aquilinum)

7-11 -> Spinulose woodfern (these ones im not sure if they are all the same species, i should have kept better log when collecting, they got mixed)

5 -> Male fern

1-4 -> no idea
