Inocybe saliceticola

Inocybe saliceticola is a fungus found in moist habitats in the Nordic countries. The species produces brown mushrooms with caps of varying shapes up to 40 millimetres (1.6 in) across, and tall, thin stems up to 62 mm (2.4 in) long. At the base of the stem is a large and well-defined "bulb". The species produces unusually shaped, irregular spores, each with a few thick protrusions. This feature helps differentiate it from other species that would otherwise be similar in appearance and habit. Inocybe saliceticola grows in mycorrhizal association with willow trees, and it is for this that the species is named. However, particular species favoured by the fungus are unclear and may include beech and alder taxa. The mushrooms grow from the ground, often among mosses or detritus. I. saliceticola was first described in 2009, and within the genus Inocybe, the species is a part of the section Marginatae. The species has been recorded in Finland and Sweden and is relatively common in some areas.......read more on Wikipedia.
