Common names: pleated inkcap, Japanese Umbrella Inky.
Extract from Wikipedia article: Parasola plicatilis is a small saprotrophic mushroom with a plicate cap (diameter up to 35 mm). It is a widely distributed species in Europe and North America. This ink cap species is a decomposer which can be found in grassy areas, alone, scattered or in small groups. The fruiting bodies grow at night after rain, and will self decompose after spore dispersion is achieved. Otherwise, they are quickly dried up in morning sunlight, or will eventually collapse beneath the weight of their caps.
Parasola plicatilis is a small to medium-sized fungus with a bell-shaped cap that ranges in color from light brown to grayish-brown, often with a distinctive umbo. It has a slender stem and gills that are crowded and free from the stem. In East and Central Texas, Parasola plicatilis typically fruits in late spring to early fall, often in fields, meadows, and along roadsides, particularly in areas with rich soil and abundant organic matter. It can be found growing solitary or in small groups, and is sometimes associated with the roots of grasses and other herbaceous plants.
