Never thought I could really find this cute species in Shanghai!
I place the mushroom in mosses to take the last pic. Their real habitat: a small trunk hidden under layers of moist bamboo litter.

Some discussion:
Many believe that Cyptotrama chrysopepla is a synonym of this species (like Michael Kuo on his website). However, a paper about Cyptotrama species from Asia (Jiao Qin & Zhu-Liang Yang 2016, the latter is a famous mycologist in China) pointed out that the two might be different species since they cluster into different branches on maximum likelihood trees, though the two species have nearly identical macroscopic features. Probably another species complex...
Anyway, note that according to Jiao Qin & Zhu-Liang Yang's research, true chrysopepla only distribute in North & Central America, so all the 'Cyptotrama chrysopepla' in China should better be called C.asprata.
