Hygrophorus eburneus – ivory woodwax

Synonyms: Agaricus eburneus, Agazicus jozzolus, Gymnopus eburneus, Limacium eburneum.

Common names: ivory woodwax, Cowboy's Handkerchief.

Extract from Wikipedia article: Hygrophorus eburneus, commonly known as the ivory waxy cap or the cowboy's handkerchief, is a species of edible mushroom in the waxgill family of fungi. It is widespread in Europe and North America, and has also been collected in northern Africa. The fruit bodies are medium-sized, pure white, and when wet are covered in a layer of slime thick enough to make the mushroom difficult to pick up. The gills are broadly attached to the stem or running down it; as the family name suggests, they feel waxy when rubbed between the fingers. Like all Hygrophorus species, the fungus is mycorrhizal—a symbiotic association whereby the underground fungal mycelia penetrate and exchange nutrients with tree roots. They are common in a variety of forest types, where they grow on the ground in thickets or grassy areas. Hygrophorus eburneus is the type species of the genus Hygrophorus. A number of biologically active chemicals have been purified from the fruit bodies of the fungus, including fatty acids with bactericidal and fungicidal activity.

AI-generated description

Hygrophorus eburneus is a small to medium-sized mushroom with a white to ivory cap, typically 2-5 cm in diameter, and a stout stem. It grows in association with oak trees, often in clusters, and is found in East and Central Texas from September to November. The fungus has a waxy texture and a mild, sweet odor. In Texas, it tends to favor well-drained soils and can be common under live oaks and other deciduous trees in woodland areas.

AI-generated summary of observations

Observations of the fungus Hygrophorus eburneus in East and Central Texas reveal its presence on well-drained slopes near water sources. On January 20, 2021, specimens were found near a small creek crossing on Sand Branch Loop Trail in Sam Houston National Forest near Montgomery, Texas. The cap surface of the mushroom was observed to be white, while the underside had a light orange coloration. A cross-section of the mushroom was also examined, providing further insight into its internal structure. The habitat of the mushroom suggests it thrives in areas with adequate moisture, but well-drained soil, allowing it to grow on slopes near creeks and water crossings. These observations contribute to a better understanding of the fungus's ecology and distribution in East and Central Texas. The specific location and timing of the observation provide valuable context for future studies.
