Licea pedicellata ( Gilbert 1934: 153) Gilbert in Martin (1942: 702). Fig. 11 .

Description:—Sporocarps black (267), about 450-520 µm in total height, stalk thick, wrinkled. Stalk continuous with outer peridium. Inner peridium surface warted. Dehiscence into irregular platelets. Spores yellowish brown (74 to 76) by transmitted light, (10.2–) 10.9–11.8 (–12) µm in diameter, minutely rough by transmitted light, densely covered by small warts under SEM.

Material examined:—LOC 22 (MYX 10485).

Habitat:—bark of living trees ( Quercus mongolica ), pH: 5.84 (n = 1).

Notes:—The shape of sporocarps of Licea pedicellata is similar to L. rugosa but differs from the former by its finely and densely warted spores ( Novozhilov et al. 2017; Figs. 15 ), which are completely smooth ( Fig. 17 J, M ) in L. rugosa . Additionally, our specimen of L. pedicellata has larger sporocarps than was noted in the description of L. rugosa ( Nannenga-Bremekamp & Yamamoto 1987; Wrigley de Basanta & Lado 2005). This species was previously found in Primorsky Krai ( Russia) in the Sikhote-Alin State Nature Biosphere Reserve ( Novozhilov et al. 2017).
