These two pictures are the same mushroom, taken seven days apart.
All micrographs except the first one are of the gill edge showing cheilocystidia, micrograph numbers 6,8,10 and 11 show the distinct bifurcate or irregularly branched cheilocystidia common in this species, I was unable to locate any pleurocystidia on the gill surface.
The long flexuous neck of the cheilocystidia, up to 12.5microns long is also visible!
