Macrolepiota zeyheri

Macrolepiota zeyheri is a species of mushroom belonging to the genus Macrolepiota, within the family Agaricaceae. This species, like others in its genus, is characterized by its large size, prominent cap, and distinctive stalk. Macrolepiota zeyheri is primarily found in woodland and grassland habitats, where it forms a symbiotic relationship with the roots of various plants, facilitating nutrient exchange in a mycorrhizal association.

Description

Macrolepiota zeyheri features a large, umbrella-like cap that can range in color from light brown to a more greyish hue. The cap surface is typically smooth, with a characteristic pattern of scales towards the center. The gills are free from the stalk and are white to cream in color, becoming more crowded as the mushroom matures. The stalk is tall, slender, and bears a ring, which is a remnant of the partial veil that covers the gills during the early stages of development. The base of the stalk may be bulbous or taper smoothly into the ground.

Habitat and Distribution

This species is found in various parts of the world, thriving in both temperate and subtropical regions. It prefers well-drained soils in open woodlands, parks, and natural grasslands. Macrolepiota zeyheri is a saprotrophic fungus, meaning it derives nutrients from decomposing organic matter, playing a crucial role in its ecosystem by recycling nutrients.

Culinary and Medicinal Use

While many species within the Macrolepiota genus are considered edible and are sought after for their nutty flavor, caution is advised when foraging for Macrolepiota zeyheri due to the potential for confusion with toxic look-alikes. Proper identification by an experienced mycologist is recommended before consumption. There is limited information on the medicinal properties of Macrolepiota zeyheri, but research into the genus suggests potential antibacterial and antioxidant activities.

Conservation

The conservation status of Macrolepiota zeyheri has not been extensively studied. However, like many fungi, it may be susceptible to habitat loss due to deforestation, urbanization, and changes in land use. Conservation efforts for mushrooms and fungi are crucial for maintaining biodiversity and the health of ecosystems.
