Plant diseases; Parasitic plants. 274. — Polt/jioruK ilri/adeux and Poll/- porus igniariiis. Destruction of Oak- wood under the combined agency of both fungi. The wood is yellowish and perforated; the medullary rays ai-e snowy-white, from the accumulation of unchanged starch, (v. Tubeuf phot.) where this fungus does great harm. They are also found, how- ever, on bark of living stems of spruce and fir. The destruction takes the form of a red-rot, the wood attacked becoming red- brown, cracked, and soft. The mycelium is found in stems and roots of trees ; in cracks in the wood and below the bark, and on the surface of timber in buildings, it forms fan-shaped strands of a permanent white colour. The mycelial strands of the " dry-rot fungus" (Mcrulius lacrymans) differ from it in being ^ Very common in Britain on dead wood, less so on living trees. (Edit.).
