Observation 79610: Leucoagaricus americanus (Peck) Vellinga
When: 2011-10-16
No herbarium specimen

Notes: This mushroom was part of a group of mushrooms that were small and large in size. It was freshly picked, about 30 minutes before the photo was taken, out of moist ground and growing just below a hugh bush of basil that was growing in my garden. I plant the basil on top of a mounded row covered by black plastic to prevent weeds. I wish I had taken a photo of them in the garden but did not realize it was so unique. It was definitely not very old and still moist but slightly leathery.

When I prepare my garden I amend the soil with mulch and this time it came from a 2 year old bed of bradford pear limbs that were chipped and piled on the foothills parkway so they they would start to rot and be a good nutrient for the garden.

There were lepotia under the other basil bush I planted about 8’ away growing at the same time and they looked totally different just like the ones in the Audubon book( Large, white, about 10" in size and made a white print.)I will upload a photo of this one also.

But, these were the same exact color of cocoa powder and looked like they had been dusted in it. I waited a few days to make a spore print so by that time it had dried too much.They did have an odd and unpleasant odor.

the brown mushroom seen in the top photos is the same type as the scaly white one seen below. The arrangement of the scales on the white one brings to mind L. americanus (formerly Lepiota americana). The spindle shaped stipe on the brown one is also a trait of L. americanus. Perhpas the brown one failed to mature in a normal fashion on account of unfavorable weather conditions. Or it may just be an old withered fruit body.
