Suggestion and question…

If you have regular tincture of iodine, this might work like Melzer’s. If you find something common from subgenus Lepidella like flavoconia or bisporigera or a rubescens-like taxon or a lepidella, you could try for a spore print, scrape some of the spores into a pile (make it big enough to see) on a piece of glass or pale colored glazed pottery and see if the tincture of iodine will turn the pile of spores dark black or blue black. If this works for you, you can do this kind of a test to check amyloidity of spores without having Melzer’s.

If you try this, let us know what the reaction was like via a pic of the darkened spore pile. It’s curious, but I’ve suggested this many times; and no one has ever shown me a picture of the result. Also curious is that with Melzer’s at hand, I’ve never tried tincture of iodine myself and haven’t had any in the house for years.

No I do not, KOH reaction was negative though

Pictured here is the smallest one, I found two growing close to each other. The larger one was badly bug eaten so I had to dispose of it, the one pictured was taken home and allowed to mature a bit. I placed the small specimen in a sealed mason jar for a day and it has grown a good bit, now I am drying it. I tried to get the dirt from the cap with a small brush but only got some of it.

Upon maturing some there is an area in the center of the cap that is depressed.

Do you have Melzer’s?

Because the margin is not striate…

and the cap is white, I’m inclined to hold back a bit on an ID to section. Melzer’s reagent on the spores will be useful. Possibilities would include species from sect. Validae or even sect. Lepidella.
