A.K.A. Japanese Umbrella Inky. A very common, small, very fragile mushroom found on lawns the day following soaking rains in summer. It appears early in the morning, but shrivels up and is gone within a few hours. The very thin, fragile stem is hollow, but this is difficult to determine unless you cut it with a very thin, sharp knife. Spore print is very dark, and relatively easy to obtain. Is similar to C. lagopus, but the latter has spores that are not as broad, and is a woodland species. Close examination by Dr. Methven (see annotation above) combined with the 2015 DNA analysis confirmed that this specimen is Parasola plicatilis. For further information on this species, not this exact specimen, go to Michael Kuo's website: http://www.mushroomexpert.com/parasola_plicatilis.html
