Cyclocybe erebia, also known as the dark fieldcap, or sometimes Agrocybe erebia, is a species of brown-spored agaric with a wide distribution. It occurs in the Americas, Europe, and parts of Oceania. It is a member of the family Strophariaceae.
Description
[edit]Appearance
[edit]The color of the cap can range from a light brown color to a darker brown color. When wet, it is slimy, or viscid. The cap can range from 1.5 to 5 cm (0.59 to 1.97 in), with younger caps being very round. The edge of the cap is often frilled or wrinkly, and more lightly colored. Decurrent gills are present underneath the cap. They are whitish at first, but they become brown with maturity. The stipe is whitish, browning with age, 4–8 cm (1.6–3.1 in) long, and 3–10 mm (0.12–0.39 in) thick. The flesh does not stain.[1]
When young, a partial veil is present, covering the hymenium. It later separates from the margin, sometimes leaving behind a white ring.[1]
Microscopic features
[edit]The spores measure 10 μm–15 μm × 5 μm–7 μm (0.00039 in–0.00059 in × 0.00020 in–0.00028 in), and are ellipsoid or subellipsoid, often with a snout-like end, and are brown or yellow-brown.
The basidia are 2-sterigmate.
Taxonomy
[edit]Cyclocybe erebia was once considered to be in the genus Agrocybe, but recent DNA sequencing has shown that it is not, instead placing it in Cyclocybe.[2]
