cystidia

In the family called Hymenomycetes there are mixed with these, and closely packed together, one-celled sterile structures named cystidia.

The = gills = are free, with a clear white space between stem and rounded edges, crowded, narrow (about 3 -- 4 mm. broad) edge finely fimbriate, probably formed by numerous bottle-shaped cystidia on the edge, and which extend up a little distance on the side of the gills, but are not distributed in numbers over the surface of the gills;

The dark color of the lamellæ in _L. corrugis_ is due to the number of brown cystidia or setæ, in the hymenium, which project above the surface of the gills, and they are especially abundant on the edge of the gills.

The surface of the gills as well as the edges is provided with clavate = cystidia = which are filled with a yellow pigment, giving to the gills the bright yellow color so characteristic.

Lamellæ or gills radiating from the point of attachment of the pileus with the stipe or with the substratum in the sessile forms; lamellæ simple or branched, rarely anastomosing behind, clothed externally on both surfaces with the basidia, each of which bears four spores (rarely two), cystidia often present.

Where the cystidia are fewer in number or are lighter in color the lamellæ are lighter colored.

The long, dark cells are brown cystidia, termed spicules by some to distinguish them from the colorless cystidia.

One very characteristic feature of the plant is the presence of = cystidia = in the hymenium on the gills.

The = cystidia = are fulvous, fusoid, 75 -- 90 µ long.

Fruiting surface, or hymenium, formed of numerous crowded perpendicular basidia, the apex of the latter bearing two to six (usually four) basidiospores, or the basidiospores borne laterally; in many cases cystidia intermingled with the basidia.
