vastinparilla

Vastinparilla is a genus of fungi in the family Inocybaceae. These fungi are known for their small to medium-sized fruiting bodies, which are typically umbrella-shaped with a prominent cap and a stem. The cap surface can vary in texture, often being smooth or slightly fibrillose. Gills are generally attached to the stem and can be crowded. The color of vastinparilla species ranges widely, from pale browns and grays to darker earthy tones. Spore prints are typically rusty brown.

Species within the vastinparilla genus are often found growing in soil or on decaying wood in forests, forming mycorrhizal associations with trees. They are distributed globally, though their specific habitats and host preferences can vary. Many vastinparilla species are considered saprotrophic, contributing to the decomposition of organic matter. However, some members of the Inocybaceae family, to which vastinparilla belongs, are known to contain toxins, making identification and edibility a significant concern for mushroom foragers. Due to the potential for toxicity and the difficulty in distinguishing between species, caution is advised when encountering vastinparilla mushrooms. Further research is ongoing to fully understand the ecological roles and chemical properties of the various species within this genus.
