Errr… where are pleurocystidia found? Let me see if I have all this straight: caulocystidia are at the top of the stipe, cheilocystidia are on the edge of the gills, chrysocystidia are… what, yellow? I’m sure I’m missing a few.

I did not see any gelatinous matrix in the cuticle, it was a tightly packed brickwork of rectangular cells. I presume the hyphae would appear more sparse under LM if they were in a gelatinous matrix? I’ll upload a better drawing a made a few days ago.

I really need to get a book describing all these terms and techniques, don’t I? Any suggestions, or as in lichenology, does every mycologist define these things slightly differently, and as a result no authoritative manual exists?

Thanks for all the comments on this. I’m learning a lot.
