Our specimens don't resemble C. japonica Yasuda in having the thick and furrowed pileus. We emphasize that the ascospores are regularly arranged or parallel, become multiseptate and bua in the asci. The paraphyses swell at their tips and are less branched compared to Yasuda's description (Yasuda, 1915). Navashin solution was suitable for maintaining the specimens. | |||
