Phlegmacium caesiocolor

Ciri dan struktur

The cap (pileus) of Phlegmacium caesiocolor measures 5–9 cm in width and develops from hemispherical to convex, eventually becoming flattened-convex. It has a slightly sticky surface with natural fibrous patterns that become more pronounced toward the margin. The cap displays a bluish-violet to violet-brown colouration. The gills (lamellae) are notched where they meet the stem, closely spaced, and undergo a colour transformation from pale greyish-brown with bluish tints when young to pale brown or brown as they mature. The stem (stipe) is 6–10 cm long, measuring 1–2 cm thick at its top and widening to 2–3.5 cm at its base, giving it a club-like shape. It appears primarily whitish with subtle bluish tints at the apex. The universal veil (the protective tissue covering the immature fruiting body) is initially pale blue before transforming to brown, and is present in sparse amounts. The flesh (context) displays blue colouration throughout or may be partially whitish while maintaining blue areas near the gills. The fungus has no distinctive odour. When potassium hydroxide (KOH) solution is applied to the flesh, it produces a yellow reaction. Dried herbarium specimens (Latin: specimina exsiccata) appear pale greyish-brown to violet-brown in the cap region, with the stem showing pale greyish-brown colouration that darkens to brown at the base. Microscopically, the spores measure approximately 9.9 micrometre (μm) in length by 5.8 μm in width, with a ratio of length to width averaging 1.70. They have a weakly lemon-shaped appearance, sometimes featuring a slight depression on the side facing the attachment point.

Reproduksi

Microscopically, the spores measure approximately 9.9 micrometre (μm) in length by 5.8 μm in width, with a ratio of length to width averaging 1.70. They have a weakly lemon-shaped appearance, sometimes featuring a slight depression on the side facing the attachment point. The spores are dark-coloured, moderately reactive with Melzer's reagent (dextrinoid), and distinctly warty with interconnected surface projections. The spore-producing cells (basidia) measure 30–41 μm by 7.5–9.0 μm, are club-shaped with four spores each, and contain reddish-brown pigmentation often with red particles.
