Merulius corium. Fr.
Resupinate, effused, soft, papery, circumference at length free, reflexed, white, villous below. Hymenium netted, porus, pallid, tan-color.
Found on decaying-branches. Quite common.
Merulius lacrymans. Fr.
Resupinate, fleshy, spongy, moist, tender, at first very light, cottony and white; when the veins appear they are of a fine yellow, orange or reddish-brown, forming irregular folds, so arranged to have the appearance of pores (but never anything like tubes), distilling when perfect drops of water which give rise to the specific name "weeping."
Dr. Charles W. Hoyt of Chillicothe, brought to my office two or three plants of this species that had grown on the under side of the floor in his wash-house. When he took up the floor the workmen discovered a number of pendant processes, some oval, some cone-shaped. Some were eight inches long, very white and beautiful but clearly illustrating the weeping process. The doctor called them white rats suspended by their tails.
Dædalea. Pers.
Dædalea is used with reference to the labyrinthiform pores; so named after Dædalos, the builder of the labyrinth of Crete.
The hymenophore descends into the trama without any change, pores firm, when fully grown sinuous and labyrinthiform, lacerated, and toothed. The habits of Dædalea are very much the same as Trametes, but they are inodorous. Care should be taken not to confound them with the species of Polyporus that have elongated curved pores.
