Marginate-bulbed Armillaria.

Figure 41.—Armillaria bulbigera. Reddish-gray caps and short bulbous stems.

Bulbigera is from bulbus, a bulb, and gero, to bear.

The pileus is fleshy, three to four inches across, convex, then expanded, obtuse, even, brownish, gray, sometimes reddish, dry, fibrillose near the margin.

The gills are notched at the stem, pallid, crowded at first, at length rather distant, becoming slightly colored.

The stem is distinctly bulbous, two to three inches long, stuffed, pallid, fibrillose, ring oblique, fugacious. The spores are 7–10×5µ.

I have found some very fine specimens in Poke Hollow, near Chillicothe. The stems were short and very bulbous, having hardly any trace of the ring on the older specimens. The caps were obtusely convex and of a grayish rufescent color. This species can readily be distinguished by the distinctly marginate bulb at the base of the stem. The specimens in Figure 41 were found in Poke Hollow, near Chillicothe, October 2d. I have no doubt of their edibility but I have not eaten them.
