Tricholoma murrillianum is a species of mushroom belonging to the genus Tricholoma. It is part of the fungal family Tricholomataceae. This species is found in North America, where it forms symbiotic relationships with coniferous trees, particularly under pines. It is one of the many species of mushrooms that are not only integral to forest ecosystems for their roles in nutrient cycling and as mycorrhizal partners but also of interest to mycologists and mushroom foragers.

Description

Tricholoma murrillianum mushrooms have a distinctive appearance that can aid in their identification. They possess a cap that is typically broad and convex, with a smooth, often sticky surface when wet. The color of the cap can vary but often exhibits shades of grey or brown. The gills are white to light grey, crowded, and attached to a stout stem that shares the cap's coloration but may be paler.

The flesh of the mushroom is white and does not change color upon being cut or bruised. Tricholoma murrillianum has a mild to slightly floury taste and odor, characteristics that are common within the Tricholoma genus.

Habitat and Distribution

Tricholoma murrillianum is primarily found in coniferous forests across North America. It forms ectomycorrhizal associations with pine trees, facilitating the exchange of nutrients between the soil and its host. This ecological relationship is crucial for the survival and growth of both the mushroom and the tree. The species tends to fruit in the late summer to fall, often appearing after rainfall.

Edibility

The edibility of Tricholoma murrillianum is a subject of debate among foragers. While some Tricholoma species are considered edible, others are known to be toxic. Therefore, without specific, reliable information on the edibility of Tricholoma murrillianum, it is recommended to err on the side of caution and not consume this mushroom.

Conservation

As of now, there is limited information on the conservation status of Tricholoma murrillianum. However, like many fungi, its existence is closely tied to its habitat. The preservation of coniferous forests is essential for the survival of this species. Changes in forest management practices, deforestation, and climate change could potentially impact the populations of Tricholoma murrillianum.
