Habitat:—bark of living trees ( Abies holophylla , A. nephrolepis , Acer ukurunduense , Alnus hirsuta , Betula schmidtii , Phellodendron amurense , Pinus koraiensis , Quercus mongolica , Taxus cuspidata and Tilia amurensis ) and plant litter (in mixed forest), pH: 4.13–6.42 (n = 72).

Notes:— Licea operculata is the most common species of the genus Licea in KPSNBR. It is easily recognized by large stalked sporocarps that dehisce with a distinct operculum. Spores appear smooth or slightly rough by transmitted light, however SEM shows that the spores are densely covered with small warts. Under SEM, the inner peridium is covered with two types of warts: smaller simple ones and larger complex ones that consist of several warts clustered together, like raspberries.
