taken in bright of day, with a black background. all were shaded with lighting umbrellas. i also used a reflector so shine on the pileus because the angle was no good for natural light

I would like to know how photo #1 was taken. The cap shines with almost metallic sheen.

Thank you

I will do that when i get the chance, great idea. Let me know if you think of anything else, looks like I will be doing many observations like this in the future.

When posting individual spore sizes, its easier to read and work with if you post them in order from smallest to largest. :)

But you’ve seen nothing yet’

probably the most photos in an observation right now, and will be when im done…
still lots more of the High mag macro to edit and upload, and I have more Micro to post.
=)

Thanks.

I’m pretty convinced this one is one of the best Panaeolus cinctulus observations at MO.

… points in the direction of P. cinctulus. P. fimicola is solitary to gregarious in habit. P. olivaceus can have a cespitose habit but I only saw it once; it is almost always solitary to gregarious.
