THE TRANSLOCATION OF PROTOPLASM 93 



XV. Pezizeae : Sclerotinia Fuckeliana (the conidia -forming 

 mycelium, Botrytis cinerea, and mycelial branches 

 with spermatia only investigated, in both the 

 connexions could be seen splendidly), Sclerotinia 

 Libertiana (sclerotia), Sclerotinia Rhododendri 

 (sclerotia), Humaria scutellata (connexions found 

 in all parts of the fruit-body, they can be especially 

 well seen where they go into asci and paraphyses ; 

 in the small bristles at the margin of the apothecium 

 large open pores can be seen in the septa), Peziza 

 acetabulum (connexions found in all parts). 

 XVI. Helvellaceae : Helvella esculenta (young fruit -bodies in 

 which the hymenium had not yet developed were 

 investigated and everywhere connexions could be 

 seen splendidly). 

 XVII. Tuberaceae : Tuber melanosporum (connexions found 



everywhere). 

 XVIII. Fungi with an imperfectly investigated life-history : 

 Achorion Schoenleinii (connexions everywhere 

 present, the thickest 1 [x in diameter), Oidium 

 subtile (or Microsporon furfur, the connexions are 

 extremely fine), Oidium albicans (the mycelium- 

 forming form investigated, the connexions are 

 extremely fine), Oidium lactis (this fungus has no 

 connexions). 

 XIX. Fungi not identified. In one, obtained from a pine- 

 board, the connexions between the cells in the 

 multicellular spores could be seen even with a low 

 magnification.

 mycelial cells (Fig. 49, Nos. 1-6, 8, and 9) ; the cells of sclerotia
