General Description:

They grow on organic matter: herbaceous of woody debris, and as far as sect. Coprophilae is concerned, on dung of herbivores. It also includes two species formerly placed in the genus Melanotus. Experimental studies have proved that these are closely related to Deconica, and must be considered pleurotoid members of that genus only.

Diagnostic Description:

1. Surface of pileus. Many species have a sticky, viscid surface. It is very important to know whether the cuticle can be lifted of entirely as a thin, transparent pellicle.

2. Presence or absence of veil which is visible in mature fruitbodies as fibrillose patches on the surface of the pileus, sometimes adhering as flocks along the margin of the pileus, and of a ring or ring-like zone on the stipe. Sometimes veil is present as a fine dusty layer on the entire surface of the pileus (D. castanella)

3. The color of the mature lamellae. sect. Deconica is divided in two subsections on account of the color of the lamellae and spores. The group of D. inquilina has thinwalled spores which are pale brown in mass. The lamellae in this group are generally pale when mature. The second group of D. montana has thick-walled spores and accordingly dark purple brown lamellae when mature.

4. Spores: apart from the size, the shape of the spores is very important. Many species have spores that are flattened: the side-view is much narrower than the frontal view. The more this difference, the stronger the spores are flattened. In those cases you will find many spores lying on the broadest side in a microscopic preparation In D. phyllogena this can be more than 90 % of the spores.
