 elongated rootlets whose epidermal cells never develop as root- 

 hairs, but become filled with coils of fungoid hyphae. 



Schlicht mentions a large number of herl>uccn> plant.- nut of 

 the mo.-t widely ,-eparated genera of Anginspenu>. tin- liner mnt> 

 nf which he found regularly developed as mycorhiza. These. lm\v- 

 ever, possess in addition imrnial root-hairs, which without doulit 

 function as such. The endntrophic coils of fungi are situated in 

 tlir inner cells of the cortex surrounding the conductive tissues, 

 and Schlicht regards them as important in transmitting to the 

 conduct in;.: tissues substances taken up by the root-hairs. Since. 

 however, the fungus inhabits living cortical cells, it is quite 

 possible that these transmit the food-materials direct without 

 the aid of the fungus. 



Schlicht found endotrophic mycorhiza on Leguniinosae, while 

 Frank found them on the alder, both being distinct from the 

 well-known tubercles of these plants. 



Kuhn 1 and (inebel- found endophytic root-fungi on Alarat- 

 tiaceae, Ophioglosseae, and /,//r,yy^///>/// ; Kuhn also found spores 

 which resembled those of /v-// /'//:/'/. 



Endotrophic mycorhiza are also present in saprophyiic gieeii 

 orchids, as well as in hcmi apmphyt ic orchids without green 

 colour: and Meincke :; found hyphae passing through the little 

 cells of the endodermis of the aerial roots of orchids into the 

 mucilage-masses of the rind-parenchyma. Schimper found fungi 

 on the adherent side of the roots of epiphytic orchids. 



Mycodomatia of Myricaceae, Elaeagnaceae, and the 



Alder. 1 



The above-mentioned plants possess a well-developed and 



normal root-system, and also characteristic lateral outgrowths.
