context_page_description: 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 across, and tall, thin stems up to 62 millimetres 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.
context_section_description: The irregularly shaped spores measure from 7.2 to 11.6 by 5.1 to 7.9 micrometres (μm), each featuring a few thick protusions. Abnormal spores of a different shape, sometimes with protrusions more distinct from the actual spore than is typical, can sometimes form; this is perhaps due to poor weather. The club-shaped basidia measure 25 to 40 by 9 to 14 μm, and each basidium bears four spores. The yellowish pleurocystidia (cystidia on the face of the gill) are ventricose or occasionally club-shaped, measuring 41 to 89 by 12 to 23 μm, including a cell wall up to 4.5 μm thick. The tip often bends and is encrusted with crystal-like structures, while the base tapers, or narrows into a small stalk. The cheilocystidia (cystidia on the edge of the gill) are much the same, but they are typically somewhat shorter and stouter. The longer caulocystidia (cystidia on the stem) occur all the way down the stem and measure up to 99 μm in length with a more variable shape. The mushrooms also feature "paracystidia", club-shaped cystidia-like structures on the gills lacking crystals, as well as "cauloparacystidia" on the stem. In Inocybe saliceticola, the paracystidia are fairly abundant, with thin cell-walls, while the abundant cauloparacystidia can have slightly thicker walls and are often arranged in clusters.
