small parasol mushrooms

Thank you, Mariana. I agree with you. These mushrooms were beautiful, like snowflakes, and like snowflakes, they melted away in the hot sun.

In another forum, Agaricaceae Chevall has been suggested for this spotting.

Leuba - thanks for the suggestion. I checked my primary reference, Mushrooms of Hawaii by Hemmes and Desjardin. This spotting does bear some resemblance to some of the Leucoagaricus species described in that book, but it also differs from all of them because it lacks an annulus on the stipe. However, the book is not encyclopedic, nor does it claim to be, so your hunch may be spot on. I returned to the spotting site today and found only remains. It looked as if the specimens had melted. There had been some overnight rain. I don't know if there is a connection. Certainly, I heard no cries of "I'm melting . . ." Despite having only goo to work with, I brushed back to leaves to check on whatever was left of the base of the stipe. It appears as though it may have been bulbous. Conclusion: none. This spotting may be Leucoagaricus sp, or not.
