Mycena purpureofusca – Purple edge bonnet

Synonyms: Agaricus purpureofuscus, Prunulus purpureofuscus.

Common name: purple edge bonnet.

Russian name: Mitsena temno-purpurnaya.

Extract from Wikipedia article: Mycena purpureofusca, commonly known as the purple edge bonnet, is a species of agaric fungus in the family Mycenaceae. First described by Charles Horton Peck in 1885, the species is found in Europe and North America, where it grows on the decaying wood and debris of conifers, including cones. Fruit bodies have conical to bell-shaped purple caps up to 2.5 cm (1 in) set atop slender stipes up to 10 cm (4 in) long. The mushroom is named for the characteristic dark greyish-purple color of its gill edges. In the field, M. purpureofusca mushrooms can usually be distinguished from similar species by characteristics such as the dark purple gill edges, the deep purple cap center, and its cartilagineous consistency. The fungus contains a laccase enzyme that has been investigated scientifically for its potential to detoxify recalcitrant industrial dyes used in textile dyeing and printing processes.

AI-generated description

Mycena purpureofusca is a species of mushroom that belongs to the family Mycenaceae. It has a small to medium-sized cap, typically 1-3 cm in diameter, with a bell-shaped or conical shape and a distinctive purple-brown color. The stem is slender and hairy, often with a pinkish-purple tint. In St. Petersburg, Leningrad Oblast, and north-western Russia, Mycena purpureofusca has been found growing in moist, shaded areas, particularly in deciduous and mixed forests, often associated with mosses, ferns, and other vegetation. Fruitings typically occur from late summer to early autumn, with a peak in September. The species is considered rare in the region, but can be locally abundant in suitable habitats.

AI-generated summary of observations

Observations of Mycena purpureofusca in Leningrad Oblast and north-western Russia reveal that the fungus grows in various locations, including Sosnovka Park and areas near Saint Petersburg. The mushrooms were found on rotten wood, logs, and birch trees, indicating a preference for decaying organic matter. They were observed in different stages of growth, from young to mature, and often in association with other fungi, such as bonnet mold fungus Spinellus fusiger. The mushrooms were typically pinkish or purple in color, with some variations in hue. Observations were made during the summer months, from July to September, suggesting that this is the peak growing season for Mycena purpureofusca in the region. The fungus appears to be widespread in the area, with sightings reported in multiple locations over several years.
