Observation 4631: Lepiota magnispora Murrill
When: 2007-10-27
No herbarium specimen

Notes: Ok, two different ones here. The first one here I thought might be L. josserandii, but looking at the spore, that isn’t true. The stipe was smooth, but this was because it handled so much by many students. The stipe of the second one is more like L. magnispora, but it also looks just like L. spheniscispora. And as far as I can tell the spores on these two species are also the same. But also as far as I can tell, if you find it up north it is L. magnispora, so there you go. Used to be L. clypeolaria, but the stuff in CA was found to be L. magnispora. So, found in the north of CA with spores like this, that is the basis of the id.

The micro shot is at 400x, with 2.5 microns per division, mounted in Meltzer’s reagent. The red color is the dextrinoid reaction with the reagent. The spores here are about 17 microns long, magnispora is a good name for this one.
