Observation 70000: Bolbitius reticulatus (Pers. :Fr.) Rick.
When: 2011-06-22
Herbarium specimen reported

Notes: (I apologize in advance for the not-so-great macro photos)

I didn’t get a chance to write a description for this one…

Structures on gill’s edge: Balloon-like (?), some are small and round and some are large and elongated.

I believe pileocystidia are present.

The pileipellis had odd structures protruding from it…there was a lot going on up there so I didn’t really know what I was looking at.

Spores:
Spore Measurements will be posted tomorrow (hopefully)
Thick-walled

Would this be a pileocystidium?

more pileocystidia (?)

Cross-section 100x, I put a drop of 5% KOH on it the soaked some of it up, then applied a drop of Lactophenol Cotton Blue. Some parts didn’t get stained like I wanted but it’s all good.

400x, vein-like structures in the area of the cap before you get to the piliepellis, I forgot what this area is called…(damn, I need to study more often!)

I think this shows the pileipellis but I’m not sure… but there are the “vein-like structures” again…

Thanks Alan!
I’ll check into it a little more, but it appears that it could very well be B. reticulatus.

I’ve never heard of brachybasidioles before.
Is there a reason that the brachybasidioles were only on the edge of the gill?

Your cheilocystidia might be brachybasidioles.
