Notes: this one is odd, look like a tricholoma but have free gill and a nice amanitoid ring, i still have the specimen and i am trying to do a spore print, not sure if it will work however.

under human planted pine forest (probably around 60year old) single specimen found.

spores 8-9*5.5-6.5

I tryed with a ruler, and used an integrated progam, i get the same size each time, i guess it is due to a optical illusion.

this is obviously not an agaric with the white spore print , i don’t know any lepiota with that aspect , but i guess it could be Leucoagaricus rubrotinctus?

Your spore measurements do not seem to match the spore size….

in the microphotograph…given the size of the scale bar, they seem to be under 6 micrometers long.

Hello, Jonathan.

The spores are very, very small for an Amanita. Amanitas with such small spores only occur in tropical forest…as far as anyone knows. The cap surface also does not seem right for an Amanita. How about a lepiotaceous species? or an Agaricus?

Very best,

Rod
