But what were they?
At first I thought they were The Miller and was looking forward to having a mushroom pasta supper but I did a spore print just to be sure and it was white so not the Miller (Pink). I checked with an expert and it was suggested they were Trichomnas sp., aka Knights. Now it didn't look like a knight to me so without a 100% positive identification, no mushroom is worth eating.
This print is made using wild mushrooms picked sustainably in the garden. The frame (purchased) is 50cm high x 70cm length x 4cm deep which can be hung. I used black mount board card and a black deep-set frame with perspex.
