Mycena atkinsoniana

Ciri dan struktur

The cap is 1 – 30 mm broad, initially obtuse to convex, later becoming broadly umbonate. Eventually the cap flattens, sometimes with the disc (the central region of the cap) slightly depressed. The cap margin initially touches the stem; as it expands it becomes somewhat wavy. The extreme margin is marked by small lines, grooves or ridges when the cap is moist. The cap is initially covered with white powdery granules, but this later sloughs off to leave a smooth surface. The disc is brownish when young, but soon develops reddish tones; older specimens are bay to Isabella, with lighter-colored margins. The flesh is buff-colored, and oozes an orange-yellow juice when cut. The gills have an adnate attachment to the stem. They have a close to moderately crowded spacing, with between 23 and 26 gills reaching the stem. The gills are narrow to moderately broad, chamoisee when young, somewhat darker in age, with edges that are maroon, and either crenulate (finely scalloped) or even. The stem is 2 – 4 cm long, 2–3 mm thick, and more or less equal in width throughout. The stem base is rooted among the leaves and debris, and the base is covered with short stiff hairs pressed flat against the surface. Its surface is covered sparsely with minute purplish brown fibrils. The stem is dull reddish brown overall, but the color fades near the top. When mushroom tissue is cut or injured, it oozes a dull reddish-brown juice or, in old specimens, a dull orange juice. M. atkinsoniana mushrooms have no distinctive taste or odor. The spores are narrowly to broadly ellipsoid, amyloid (staining black to blue-black in Melzer's reagent), and measure 7–9 by 4–5 μm.

Habitat dan peran ekologis

The fungus is saprobic, and so derives nutrients from breaking down dead plant material, such as leaves, bark, needles, and twigs, that has fallen to the ground. Fruit bodies are usually found growing in groups or scattered on leaf litter in beech and beech-hemlock forests during the summer and autumn, although it has been recorded growing on lawns. It is also often found under eastern North American oaks. The distribution includes the US states Connecticut, New York, Ohio, Michigan, and Vermont. It has also been collected in Quebec, Canada.

Reproduksi

The spores are narrowly to broadly ellipsoid, amyloid (staining black to blue-black in Melzer's reagent), and measure 7–9 by 4–5 μm. The basidia (spore-bearing cells) are four-spored and measure 28–30 by 6–7 μm. Cheilocystidia are plentiful, and arranged so as to form a sterile band on the edge of the gill. Measuring, they are narrowly fusoid (tapered at each end), smooth, and have dark reddish contents. The pleurocystidia (cystidia on the gill face) similar in appearance to the cheilocystidia but far less abundant. Gill tissue is yellowish to very faintly vinaceous-brown when stained with iodine. The tissue of the cap consists of several layers. The outer surface comprises a thin cuticle made of narrow hyphae filled with dark-reddish material.
