Iodine Bonnet Mycena filopes (Bull.) P. Kumm. syn. M. iodolens S. Lundell (illustrated 65% life size) Cap 0.5–2cm across, conical, expanding to bell-shaped; dark grey-brown with sepia flush, whitish at margin. Stem 10–40×1–3mm, base sometimes rooting; lighter than cap; base covered in fine, white hairs. Flesh pale greyish; thin; smell like iodine, especially when dried. Gills adnate with a decurrent tooth; pale grey with white edge. Spores 9–11×5-7¼, ellipsoid; amyloid. Spore print white. Basidia 4-spored. Cheilocystidia sac-like with granular warts. Habitat in deciduous woods or with pine and spruce, often on buried bark; autumn. Common. Not edible. Note in my first book this fungus was identified as M. sepia syn. M. filopes; this taxon has always been a muddle, but it has now been sorted out. It has been found that, like most of the British collections, my specimens were in fact of M. filopes; this has been re-determined by E. Emmett.
