Tricholoma vaccinum

Ciri dan struktur

The cap of T. vaccinum is initially broadly conical, then convex and finally flattened; its diameter is usually between 2.5 and 8 cm. The cap margin is initially curved inwards, and shaggy from hanging remnants of the partial veil. The partial veil is cotton-like, and does not leave a ring on the stipe. The fibrous to scaly cap surface ranges in color from reddish-cinnamon to brownish-orange to tan. The gills have an adnate to sinuate attachment to the stipe, and are crowded closely together. There are between three and nine tiers of lamellulae—short gills that do not extend completely from the cap edge to the stipe. The gills are dingy white, and frequently stain reddish brown. The stipe is 3 to 8 cm long and 1 to 2 cm thick, and becomes hollow in age. It is roughly equal in width throughout its length and ranges in color from whitish to the same color as the cap, but lighter, and sometimes with reddish-brown stains; it is lighter in color near the apex. Like the cap, the stipe surface is fibrous to scaly. The odor of the fruit bodies is unpleasant. The mushrooms produce a white spore print, and the spores are broadly elliptical, smooth, hyaline (translucent), inamyloid, measuring 6–7.5 by 4–5 μm. The basidia (spore-bearing cells) are four-spored, without clamps, and measure 17–32 by 6.0–7.5 μm. The hymenium lacks cystidia. The arrangement of the hyphae in the cap cuticle ranges from a cutis (with hyphae that run parallel to the cap surface) to a trichoderm (hyphae perpendicular to the cap surface); these hyphae are roughly cylindrical, and measure 3.5–8.0 μm wide, with roughly cylindrical to club-shaped ends that are 6.0–11.0 μm wide.

Habitat dan peran ekologis

Tricholoma vaccinum is a mycorrhizal species, and grows in association with coniferous trees, especially pine and spruce. It forms ectomycorrhizae that have been called "Medium-Distance fringe exploration type", indicative of the ectomycorrhiza's ecological role in space occupation in the soil, their possible reach regarding nutrient acquisition and their demand of carbohydrates that have to be invested by the trees for their fungal partners. Fruit bodies usually appear in groups or clusters on the ground, sometimes with moss. The fungus fruits in late summer and autumn. It is found in northern Asia, Europe, and, in North America, is widely distributed in the United States and Canada, and has also been recorded in Mexico. It is one of the most common species of Tricholoma in Central Europe, and is often found in large groups in spruce forests. It is rare in the United Kingdom, and most records have been from Scotland. The fungus may be extinct in the Netherlands. The ectomycorrhizae of T. vaccinum has been the subject of considerable research. Ectomycorrhizae of Tricholoma species can vary considerably among species in the genus, and differences in the structure of rhizomorphs (a cordlike fusions of hyphae resembling a root) have been used to key out species.

There are no clamp connections in the hyphae of T. vaccinum.
