mm broad, thin, somewhat intervenose, and whitish, with edges that are the same color as the gill faces. Takahashi's description does not include any discussion of the mushroom's edibility. Microscopic characteristics The basidiospores are roughly ellipsoid and measure 7.5–8.5 by 5–6 μm. They are thin-walled, smooth, colorless, and inamyloid to weakly amyloid—indicating a weak ability to absorb the iodine in Melzer's reagent. The spore-bearing cells, the basidia are 22–31 by 5.5–7 μm, club-shaped, and mostly two-spored. The cheilocystidia (cystidia on the gill edge) are 27–40 by 3–6 μm, abundant, and form a sterile gill edge. They are irregularly cylindrical to constricted, smooth, colorless, and thin-walled. Pleurocystidia (cystidia on the gill face) are absent. The hymenophoral tissue is made of thin-walled hyphae that are 5–18 μm wide, cylindrical, smooth, colorless, and weakly dextrinoid. The cap cuticle is made of parallel, bent-over hyphae that are 2–6 μm wide, cylindrical, and densely covered with warty or finger-like thin-walled diverticulae that are colorless and inamyloid. The layer of hyphae underneath the cap cuticle are parallel, olive-brown, and weakly dextrinoid, with short and inflated cells up to 22 μm wide. The stem cuticle is made of parallel, bent-over hyphae that are 2–4 μm wide, cylindrical, smooth to sparsely diverticulate. These hyphae curve outward to form club-shaped or irregularly shaped caulocystidia (cystidia on the stem) that are olive-brown, inamyloid, and thin-walled. They measure 13–29 by 3–7 μm, and are broadly club-shaped to irregularly shaped, and often have one to three knob-like excrescences. The stem tissue is made of longitudinally running, cylindrical hyphae that are 5–12 μm wide, smooth, colorless, and have a weakly dextrinoid in Melzer's reagent. Clamp connections are absent in all tissues of M. intersecta. Similar species The European species Mycena viridimarginata is somewhat similar to M. intersecta in appearance, but may be distinguished by its greenish-edged gills, cheilocystidia with abruptly tapering points, and clamp connections. Habitat and distribution Mycena intersecta is known only from Kanagawa, Japan. The fruit bodies are found solitary or scattered, on dead leaves in lowland forests dominated by the oak trees Quercus myrsinaefolia and Q. serrata.
