Hemileccinum subglabripes

Boletus subglabripes 318865

Hemileccinum subglabripes is a species of bolete fungus belonging to the family Boletaceae. It is found in North America, where it grows in a mycorrhizal association with hardwood trees, particularly with oaks (Quercus spp.). This species is characterized by its brown to reddish-brown cap, its stalk which is typically adorned with a fine network or reticulation at the top, and by the fact that it does not change color or stain significantly when cut or bruised. The pores of the mushroom are small and round, and they are initially white before turning a more yellowish color as the mushroom matures.

Description

Hemileccinum subglabripes features a cap that can range from 4 to 15 cm in diameter, initially hemispherical before flattening out with age. The surface of the cap is smooth to slightly velvety, and its color can vary from light brown to a darker reddish-brown. The stalk is typically 5 to 12 cm long and 1 to 2.5 cm thick, more or less equal in width along its length but sometimes enlarged at the base. It is adorned with a fine white to yellowish network at the top, becoming more smooth and reddish towards the base.

The spore print of Hemileccinum subglabripes is olive-brown. Its spores are elliptical, smooth, and measure approximately 10 to 15 by 4 to 6 micrometers. The flesh of the mushroom is white and does not change color upon exposure to air, a characteristic feature that helps in distinguishing it from similar species.

Habitat and Distribution

Hemileccinum subglabripes is primarily found in the eastern and central parts of North America, thriving in deciduous forests dominated by oaks. It forms symbiotic relationships with the roots of these trees, facilitating nutrient exchange in a mycorrhizal association. The fungus prefers well-drained soils and is typically found fruiting from late summer to fall.

Edibility

The edibility of Hemileccinum subglabripes is reported as edible, though it is not considered among the most desirable of the bolete mushrooms due to its texture and flavor. As with all wild mushrooms, caution is advised when foraging for Hemileccinum subglabripes, as it can be confused with other less palatable or potentially toxic bolete species.

Taxonomy

The taxonomy of Hemileccinum subglabripes has undergone revisions over time. Initially classified within the genus Boletus, it has been moved to the genus Hemileccinum based on molecular data which revealed distinct genetic differences from other groups within the Boletaceae family. This reclassification is part of ongoing efforts to better understand the phylogenetic relationships within this diverse group of fungi.

Conservation

There are no specific conservation concerns for Hemileccinum subglabripes at this time. It appears to be relatively widespread and common within its habitat range. However, like many fungi, it could be susceptible to changes in forest management practices, pollution, and climate change, which could impact its mycorrhizal host trees and, by extension, the populations of the fungus itself.
