This is one of the most variable I know (see my several previous observations of it). Specimens in this observation were collected at the same place, the first one only some centimeters apart from the others, they look very different from above and only the fact that they grew together and the similarity of the stem and hymenium led me to consider only one observation. The overall shape of everyone is that of a Psathyrella. However, the microscopic features are those of Parasola conopilus: Spores dark brown with central germ pore, average dimensions of ~ 15 × 8 um, pilleipellis with celular structure and presenting setae as a distinguish feature.
