Moist grassy places under trees. Washington, D.C. July. Mrs. E.M. Williams. Perhaps in the fresh state the pileus is not as distinctly rugulose as when dry. Peck, Bull. Torrey Bot. Club, Vol. 27, January, 1900.
ARMILLA´RIA Fr.
Armilla, a ring.
Armillaria mellea.
Pileus and Stem continuous. Veil partial, sometimes only indicated by the scales which clothe the stem terminating in the form of a ring. Spores white. On the ground or on stumps.
In the young plant the veil extends from the stem to the pileus, sometimes forming scaly patches upon it; below the ring it is attached to the stem often in scales.
But for the presence of the ring the species of this genus could be distributed in Tricholoma, Clitocybe and Collybia, with which they agree in all other characters.
