Field Notes
Description:
Measuring 3–7 cm (1.2–2.8 in) in diameter, the greyish or brownish-grey cap is initially bell-shaped, is furrowed, and later splits. The colour is more brownish in the centre of the cap, which later flattens before melting. The very crowded gills are free; they are whitish at first but rapidly turn black and easily deliquesce. The short stipe measures 7–17 cm (2.8–6.8 in) high by 1.5 cm in diameter, is grey in colour, and lacks a ring. The spore print is dark brown, and the almond-shaped spores measure 8–11 by 5–6 μm. The flesh is thin and pale grey in colour
Habitat:
Coprinopsis atramentaria occurs across the Northern Hemisphere, including Europe, North America, and Asia, but has also been found in Australia, where it has been recorded from such urban locations as the Royal Botanic Gardens in Sydney and around Lake Torrens, and also in South Africa.
Like many ink caps, it grows in tufts. It is commonly associated with buried wood and is found in grassland, meadows, disturbed ground, and open terrain from late spring to autumn. Fruiting bodies have been known to push their way up through asphalt and even tennis courts. It is also common in urban areas and appears in vacant lots, and tufts of fungi can be quite large and fruit several times a year. If dug up, the mycelium can often be found originating on buried dead wood

Coprinus atramentarius (Bull. ex Fr.) Fr. Common Inkcap, Tippler's Bane, Grauer Faltentintling, Coprin noir d'encre, Ráncos tintagomba. Cap 3-7cm high, ovoid at first, then broadly conical when expanded, with the margin irregularly puckered at first, then becoming split; gray to gray-brown; dry, smooth or silky with minute scales or veil remnants, especially near the center. Gills free, crowded, broad; white then lavender-gray then inky black and soon deliquescing. Stem 70-170 x 9-20mm, hollow; whitish; dry, silky-fibrous; fibrous white partial veil leaving ring zone near base. Odor faint and pleasant or none. Spores ellipsoid, smooth, with pore at tip, 7-11 x 4-6µ. Deposit black. Habitat usually in clusters on the ground near rotting or buried wood or in grass. Found widely distributed throughout North America and Europe. Season May-September (November-April in California). Edible but dangerous because it causes alarming symptoms (nausea, palpitations) when taken in conjunction with alcohol; indeed, it has been given to alcoholics to cause these symptoms and eventually cure their habit. Comment Good black drawing ink used to be made from the deliquesced caps by boiling the black "ink" with a little water and cloves.
