Extract from Wikipedia article: Chroogomphus vinicolor, commonly known as the wine-cap Chroogomphus or the pine spike, is a species of mushroom in the family Gomphidiaceae. Found in North America and the Dominican Republic, mushrooms grow on the ground under pine trees. Fruit bodies have reddish-brown, shiny caps up to 7.5 cm (3.0 in) wide atop tapered stems up to 7.5 cm (3.0 in) long. The gills are thick, initially pale orange before turning blackish, and extend a short way down the length of the stem. Although the mushroom is edible, and sold in local markets in Mexico, it is not highly rated. Distinguishing this species from some other similar Chroogomphus species is difficult, as their morphology is similar, and cap coloration is too variable to be a reliable characteristic. C. vinicolor is differentiated from the European C. rutilus and the North American C. ochraceus by the thickness of its cystidial walls.
