hemiboreaalisella

Hemiborealisella is a genus of fungi in the family Agaricaceae. It was circumscribed by mycologist Rolf Singer in 1951, and is characterized by its distinctive, often brightly colored, and typically small to medium-sized mushrooms. The genus is primarily found in the Northern Hemisphere, with a few species also occurring in the Southern Hemisphere.

Hemiborealisella species are typically agarics, meaning they have a cap, gills, and a stalk. They are often found growing in grasslands, meadows, and other open habitats. The genus is notable for its diversity of colors, with species ranging from white and cream to yellow, orange, and red. Some species also exhibit bioluminescence, emitting a faint glow in the dark.

The taxonomy of Hemiborealisella is complex, with many species described in recent years. Some species have been transferred to other genera, such as Lepiota and Leucoagaricus. Despite this, the genus remains an important one for mycologists studying the diversity and ecology of agarics.

Hemiborealisella species are not typically edible, and some are even toxic. However, they are of interest to mycologists and mushroom hunters for their distinctive appearance and the challenges they present in identification. The genus is a valuable resource for studying the evolution and ecology of agarics, and continues to be a subject of ongoing research.
