Inocybe salicis is an uncommon species of fungus found in association with willow in Europe. The species produces small, brown or yellow mushrooms with caps up to 2.5 centimetres (1.0 in) across, with stems up to 3.5 centimetres (1.4 in) long. The species is similar in appearance to several other closely related species in the genus Inocybe that also associate with willow, and so is most reliably differentiated microscopically.

Taxonomy and phylogeny

Inocybe salicis was

Salix
, the generic name for willow.

Within the genus Inocybe, I. salicis belongs to the section Marginatae, which also includes I. obtusiuscula, I. dunensis, I. salicis-herbaceae, I. substellata, I. praetervisa, I. saliceticola and I. mixtilis. These species are all known to associate with willow, and all have macroscopic similarities. As such, they are best differentiated microscopically.[1]

Description

Inocybe salicis
mycorrhizal
Edibility is unknown

Inocybe salicis mushrooms have

cap cuticle forms a cutis. The gills are almost free, meaning that they only just connect to the stem, and are initially a pale grey, becoming an ochre-grey (or brownish) as they age. The stem has a white to honey-coloured surface entirely covered in powdery granules. The stem is 1.5 to 3.5 centimetres (0.6 to 1.4 in) long by 0.4 to 1 centimetre (0.2 to 0.4 in) thick. There is a well-defined "bulb" at the base of the stem. The white flesh smells spermatic, but the scent is not distinctive.[4]

Microscopic characteristics

Inocybe salicis produces

cystidia on the face and edge of the gills measure 50 to 70 by 12 to 25 μm with a cell wall 2 to 3 μm thick, and either taper at each end, or are shaped like swollen bottles, with the cheilocystidia (cystidia on the gill edge) more variable. The circumcystidia (cystidia on the margin of the cap) are club- or balloon-shaped, and caulocystidia can be found all the way down the stem.[4]

Distribution and habitat

Inocybe salicis favours wet land in willow woodland and clearings. Although widespread throughout its range in Europe, it is not commonly encountered.[4]
