. Comparative morphology and biology of the fungi, mycetozoa and bacteria . Plant morphology; Fungi; Myxomycetes; Bacteriology. Fig. 9. Agartews melleus. Me- dian longitudinal section through the growing apex of a subterra- nean mycelial strand, seen by trans- mitted light. Magn. 40 times. Fig. 10. AgaruMS melieus. Thin median longitudinal section through the extremity of the growing apex of a subterranean mycelial strand. Magn. 350 times, but the drawing completed under higher magnifying power. • compressed or membrane-like expanded networks of strands at the cost of the sap- containing layers of tissue, and also sends out a large number of single hyphae from these strands into the rind and wood, and especially into the medullary rays, where they spread widely. From these inlra- matrical, especially subcortical, parts other strands may proceed which develope as extramairical strands usually in the soil, and are therefore subterranean, and branch and spread the Furigus 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 interspaces..
