Hello, I am experimenting with king oysters and I have a 10 bag batch going on. I have split the batch into 2 groups of 5 blocks each. In one group (say group A) I have opened the top of the bag and left the block to pin in my FC and in the second group (say group B) I have opened the top of the bag, put on a humidity tent with about 6cm squared of holes and put into the FC. Group B pinned a week before group A so the fruitbodies are more mature at this point. However I have noticed that that for group B (the ones with the tent) the stipe looks kind of wrinkled just below the gills. the stipes of group A look smoother however the fruitbodies are younger. Any ideas of what it could be? the below picture is of a young mushroom from group B.
