Sclerocystis liquidambaris Wu & Chen, Trans. Mycol. Soc. Rep. China 2: 73-83. 1987.

= Sclerocystis cunninghmia Hu, Quart. J. Chinese For. 21:45-72. 1988.

 Description: Sporocarps globose to subglobose, 300-600 × 370-680 μm, brown to dark brown, consisting of chlamydospores formed radially within the "paraphysis-like" structures. "Paraphysis-like" structures cylindrical, clavate to spathulate, yellow brown to dark brown, thick-walled, up to 200 μm long, protruding from the central plexus of hyphae or from the spore base. The apices of "paraphysis-like" structures tightly packed, forming a peridium enclosing the whole sporocarp. Chlamydospores cylindro-clavate to obvoid, (27.5-) 40-65 (-75) × (50-) 72.5-132.5 μm, brown to reddish brown, sometimes with a septum at the spore base. Chlamydospore walls brown to reddish brown, 7.5-25 μm thick at their apices, 6-10 μm thick at the base, and 2-5 μm thick at the sides. Sometimes, hyaline, thick-walled (up to 6 μm thick) structures with a membraneous outer coat are present within the chalmydospores

 Note: Sclerocystis liquidambaris produces two sizes of chlamydospores similar to those of S. clavispora (Fig. 19A). Spore size falls into two major categories, one 6000-7000 μm2and the other 2000-3000 μm2. Sclerocystis liquidambaris differs from S. clavispora mainly by its "paraphysis-like" structures which protrude out of sporal layer and form a "pseudoperidium". This species was also found in Korea (Koo et al., 1992; Eom et al., 1992).
