[Illustration: Plate VI. AGARICUS (ARMILLARIA) MELLEUS. Group from Hynesboro Park, Md., U. S. K. MAYO, del.] PLATE VI. =Ag. (Armillaria) melleus= Vahl. "_Honey-Colored Armillaria._" EDIBLE. Cap fleshy, rather thin at the margin, at first subconical, then slightly rounded, or nearly plane, clothed with minute hairy tufts; margin sometimes striate, color varying, usually a pale-yellowish or honey color or light reddish brown; flesh whitish. Gills whitish or paler than the cap, growing mealy with the shedding of the profuse white spores, and often spotted with reddish-brown stains, adnate, ending with decurrent tooth. Stem fibrillose, elastic, stuffed or hollow, ringed, and adorned with floccose scales which often disappear with age; in some varieties distinctly bulbous at the base, in others showing tapering root. Specimens occur in which the ring is wanting or only traces of it appear in the form of scales encircling the stem. Veil usually firm, membraneous, and encircling the stem in a well-pronounced ring or collar, but sometimes filmy as a spider's web, in very young specimens hiding the gills, but breaking apart as the cap expands. Manner of growth caespitose, generally on decayed tree stumps, although the group figured in the plate was found growing on moist sand, mixed with clay, on a roadside in Hynesbury Park. Authors differ widely as to the value of this species as an esculent. I have only eaten the very young and small specimens when cooked, and found them very palatable. A Boston mycophagist records it as "very good," fried after five minutes' boiling in salted water. Prof. Peck, having tried it, considers it "a perfectly safe species, but not of first-rate quality." It is very common in Maryland and Virginia, and in the mountain districts prolific. I have talked with Bohemians and with Germans who have gathered it in basketfuls in the vicinity of the District of Columbia, who speak well of it, considering it a valuable addition to the table. Its prolific growth makes it valuable to those who like it. There are no species recorded as dangerous in this group. Ag. (Armillaria) robustus, a very stout species, with a fleshy, compact, smooth cap, bay color or tawny, occurs in the Maryland woods, and in the open woods of the Massachusetts coast. AGARICINI. Fries.
