Added micrographs of spores stained with methylene blue.
They seem to have isolated warts.

This could be S umbrorum but it is vital to be able to see the type of ornamentation on the spores and it is only visible when using a stain like Lactophenol Cotton Blue. It is very easy to confuse the droplets in the spores with ornamentation without the stain. They do look to have large warts but are they isolated or connected with each other?
