Põiksime

Põiksime is a genus of fungi belonging to the family Hydnangiaceae. The genus was described in 1966 by mycologists Rolf Singer and Alfred Richard. Species within the genus Põiksime are characterized by their small to medium-sized basidiocarps, which are typically gilled and have a powdery or granular surface. The gills are often adnate or decurrent and can be free in some species. Spore prints are usually white.

The distribution of Põiksime species is primarily in temperate and subtropical regions. They are often found growing terrestrially, typically in association with trees, suggesting they may be ectomycorrhizal. This means they form a symbiotic relationship with the roots of plants, exchanging nutrients. However, the exact ecological roles and host preferences of many Põiksime species are still under investigation.

Morphologically, Põiksime can be distinguished by a combination of features including the shape and color of the cap, the attachment and spacing of the gills, and the characteristics of the spores. Microscopic examination of spores, basidia, and other hyphal structures is often necessary for accurate identification to the species level.

Current research on Põiksime focuses on its phylogenetic relationships within the Hydnangiaceae family, exploring its ecological significance, and documenting its biodiversity. As with many fungal genera, further taxonomic and ecological studies are needed to fully understand the diversity and distribution of Põiksime species worldwide.
