Licea rugosa Nannenga-Bremekamp & Yamamoto (1987: 326) Fig. 17 .

Description:—Sporocarps black (267), stalked, about 140–270 µm in total height. Sporotheca 90–140 µm in diameter. Inner peridium warted, dehiscence along preformed lines into irregular fragments. Stalk about 70–150 µm, thick, wrinkled. Spores dark brown to black in mass, dark olivaceous (108) by transmitted light, paler on one side, (10.7–) 12.5–15.7 (–17.2) µm in diameter, smooth.

Material examined:— LOC 2 (MYX 11295, MYX 11301, MYX 11307), LOC 10 (recorded only by photo), LOC 11 (MYX 10196, MYX 10202, MYX 10209), LOC 16 (MYX 10147), LOC 37 (MYX 10028) .

Habitat:—bark of living trees ( Acer mandshuricum , Chosenia arbutifolia , Kalopanax septemlobus , Quercus mongolica and Ulmus japonica ), pH: 6.40–7.27 (n = 9).

Notes:—This species has recently been found in the Russian Far East ( Novozhilov et al., 2017). The specimen MYX 10196 is identified as L. rugosa var. fujiokana . It has smaller (9.6–10.6 μm) and slightly light colored spores than L. rugosa var. rugosa , which is the main distinguishing feature of this variety (Wrigley de Basanta & Lado 2005) (compare Fig. 17 J and K ). L. rugosa var. fujiokana has sporocarps 120–195 μm in height, stalk 70–120 μm in height, and sporotheca 60–80 μm in diameter. The peridium surface in the dry state is more wrinkled than that the one in L. rugosa var. rugosa (compare Fig. 17 A–C and D–H ).
