Merulius Tremellosus is a very handsome plant with a whitish, 

 radiating, and toothed margin, and variously shaped, porous reticu- 

 lations of a reddish orange colour. It occurs occasionally on fir 

 stumps. M. Himantoides has given considerable trouble to some 

 of our neighbours by incrusting the club-mosses in their conserva- 

 tory with its thin, buff, and tawny folds, and although the boxes in 

 which it grew were destroyed, and new ones substituted, the 

 persevering pest soon reappeared, and proceeded afresh with its 

 work of devastation. M. Lacrymans is the terror of aU house- 

 owners, and avenges their neglect of fresh air by spreading through 

 the timbers, and at length reducing them to powder, thus often 

 causing a serious and hidden mischief where ventilation is prevented.
