Ciri dan struktur

The fruit bodies of Lepiota castaneidisca have white, bell-shaped to convex caps 0.8 to 3.2 cm in diameter, with an orange-reddish to pale orange-brown center. Mature specimens fade and lose the reddish shades. The cap surface develops small pale pink or cream patches (especially on the outermost zone) on a white background that has radially arranged fibrils. The gills are somewhat crowded to moderately distant, with typically 40–45 full length gills, and 1–5 tiers of interspersed lamellulae (short gills that do not extend fully from the cap margin to the stem). They are slightly ventricose, measuring 2.5–5 mm wide, and have a white fringed or irregular edge. Whitish when young and cream-colored in age, they have a free gill attachment to the stem. The stem is 25 – 65 mm long by 2 – 6 mm thick, cylindrical, slightly widened at the base, hollow, and fibrillose. Its color is pinkish in the lower part, and it stains reddish where damaged, especially in older specimens. The flesh is whitish, sometimes with cream tones, or reddish-brown in mature specimens. There is a ring that points upward in young specimens, but in maturity it degrades to remnants that are left behind on the stem. It has a sharp odor similar to rubber or cod liver oil. The mushroom is not known to be poisonous, but consumption is not recommended due to the risk of possible confusion with Lepiota species that contain deadly amatoxins. The smooth, dextrinoid spores are in side view triangular with a spurred base, in frontal view oblong, and typically measure 5–9 by 3–4 μm. Staining with Cresyl blue shows them to be somewhat metachromatic, and binucleate.

02 / Kehidupan

Habitat dan peran ekologis

Lepiota castaneidisca is a saprobic fungus. Fruit bodies appear in the late fall and winter (November to February), where they grow gregariously near cypress, redwood or in mixed coast live oak forests. The fungus is common in coastal and northern California, and is often found in the San Francisco Bay Area. The northern limit of its distribution is Washington state and southern British Columbia, and it has been recorded as far south as Mexico.

Reproduksi

The smooth, dextrinoid spores are in side view triangular with a spurred base, in frontal view oblong, and typically measure 5–9 by 3–4 μm. Staining with Cresyl blue shows them to be somewhat metachromatic, and binucleate. Cystidia on the gill edge (cheilocystidia) are club-shaped to cylindric or sometimes spheropedunculate (somewhat spherical with a stem), and have dimensions of 20–44 by 6.5–13.5 μm. Basidia are 18–30 by 5–8 μm, mostly four-spored, and are absent on the gill edge. Pleurocystidia (cystidia on the gill face) are absent. The cap cuticle is a hymeniderm (lengthened cells arranged side by side) with mostly colorless elements of different lengths, measuring 16–62 by 8–18 μm. The stipitipellis (outer covering of the stem) comprises a layer of colorless hyphae measuring about 2–3 μm wide.

Ringkasan sumber

Lepiota castaneidisca is a species of agaric fungus in the family Agaricaceae. Formally described in 1912, it was for a long time considered the same species as the similar Lepiota cristata until molecular analysis reported in 2001 demonstrated that it was genetically distinct. It is most common in coastal and northern California, and has also been recorded in Mexico. A saprobic species, it is usually found under redwood and Monterey cypress. Its fruit bodies (mushrooms) have white caps with an orange-red to orange-brown center that measure up to 3.2 cm wide.
