Cyptotrama asprata

Ciri dan struktur

The cap is 0.6 to 2.7 cm in diameter, convex to cushion-shaped. The cap surface is dry, and younger specimens are covered with characteristic spikes; as the spikes break up with age, they tend to look more hairy or woolly. Older specimens typically have the surface features worn off. The cap margin tends to be rolled inwards when young, gradually becoming straight with maturity. The color of the cap is bright or pale yellow, increasing in intensity towards the center of the cap. C. asprata has a web-like ring that soon disappears. The gills, pale yellow to white in color, are distantly spaced and have an adnate (squarely attached) or short decurrent (running down the length) attachment to the stem; they feel greasy when dried and crushed. The stem is 1 to 6.7 cm long by 0.2 to 0.4 cm thick at the stem apex; the stem is slightly thicker towards the base, and may be covered with hyphae that appear woolly (flocculose) or hairy (fibrillose). The surface of the stem may also be scaly – especially towards the base – or it may be covered with very small particles (granular). The flesh of this mushroom is white or pale yellow, with no distinctive taste or odor. Spores are thin-walled, smooth, and ellipsoidal or oval in shape. Viewed with a microscope, they appear translucent (hyaline), and stain red or blue with Melzer's reagent (inamyloid). Their dimensions are typically 7–10 by 5–7 μm; the spores contain a single large oil droplet. The spore-bearing cells, the basidia, are club-shaped, two- to four-spored, and 25–30 by 5–7 μm. The presence of sterile cells called pleurocystidia (large cells found on the gill face in some mushrooms) is uncommon; specimens may contain few or abundant cheilocystidia (large sterile cells found on the gill edge) that are club-shaped, thin-walled and 39–87.5 by 8.5–16 μm in size.
