From these intra- malrical, especially subcortical, parts other strands may proceed which develope as ex I ram a trica I strands usually in the soil, and are therefore subterranean, and branch and spread the Fungus over wide distances from one tree to another. These strands become more than 3 mm. thick and are round on the transverse section ; they can also develope into enormous masses in moist rotting timber. The cylindrical subterranean strands consist when fully formed of a dark-brown, brittle, usually smooth peripheral tissue or rind enclosing a white finely-felted me- dulla. The rind, which in stout specimens has the thickness of paper, is formed in its outer portion of about twelve or more layers of cell-rows (hyphae) running down the length of the strand, and connected with one another laterally without Fig. 11.
