Some similarities to :
Firerug Inkcap which is larger at 4cm across than the 3cm of Glistening Inkcap and also has larger flecks of a frosty-looking substance upon its elongated egg-shaped creamy ochre cap.
Firerug Inkcap is also of a lighter colour than Glistening Inkcap, and doesn't grow in large colonies, but singly or in small groups, sometimes arising from burnt ground on buried wood.
Glistening Inkcap has an egg-shaped brown cap, initially covered in frost-like white flecks that look superficially like mica flakes but they soon fall off. The body or cap is indistinctly striated below the apex and at first is ovate, but the edges start to curl upwards and the body split as it turns black. The stem or stipe is off-white, narrow and slightly yellowish. It grows in clusters preferentially on dead deciduous wood, but can also grow on dead coniferous wood. The gills, white at first, like most inkcaps, deliquesce within a day turning into an oozy black liquid which contains the black spores.
Micaceol, a steroid named after this species of mushrooms, exhibits slight anti-bacterial activity. It is a yellow amorphous solid.
(Z,Z)-4-Oxo-2,5-HeptadieneDioic Acid is an unusual un-saturated di-carboxylic acid, and exhibits
Glutathionine S-Transferase inhibition (a GST inhibitor).
Found clustered on decayed stumps or buried wood of deciduous trees, rarely on coniferous wood.
Some similarities to other Inkcaps such as :
Firerug Inkcap (Coprinellus domesticus) which is also reddish brown and also has small whitish scales on the cap that soon fall off, but the white scales are larger than those on Glistening Inkcap and do not glisten like frost.
There are two distinct populations of Inkcap, this one and others are in the Brittlestem Family [Psathyrellaceae], whereas
Shaggy Inkcap is in the Agaricaceae Family. Both dissolve themselves into a black liquid.
