The fruiting body has an agreeable odor when young but when old and in the stages of decay emits foul odors and in- jurious gases and an excessive amount of water may be exuded by the diseased Fig. 122.—The dry-rot fungus (Merulius lacrymans). Later decay stages than that shown in Fig. 121. From the board shown on the left, the mycelial felt has been removed and the checked portion of the board is seen. This appearance is caused by the drawing of the tissues in drying after the decay has been well started. The removed mycelial felt is shown in Fig, 5. The board shown on the right is in a still further stage of decay and the wood under the mycelium is reduced to friable punk. Original.
