wholly of Greek derivation, whilst fungologists is an ugly- 

 compound of Latin and Greek. 



Endophytic, "inside of plants," growing in the substance 

 of any vegetable (plant or tree). 



Epiphytic, "outside of plants," growing on the surface 

 (leaves, bark, or roots) of any vegetable. 



Aerobic, requiring air in order to live ; applied to bacteria. 



Anaerobic, not requiring air or oxygen, even sometimes 

 killed by them. 



Rhizomorph, a developed form of the mycelium of fungi. 

 It is named from its resemblance to a root. From the rhizo- 

 morph hyphae may spring and grow into the wood itself. A 

 Rhizomorph may be regarded as being itself the hypha of a 

 fungus which has thickened and assumed the appearance of a 

 root. They are met with either in earth or the bark of trees, 

 and are often of great length and exactly like the slender 

 roots of plants. Hence the name. 



Lumen, the enclosed cavity of any tube. 



Ozoto-bacter, a name given to a microscopic organism 

 present in soils which has the power of fixing nitrogen. The 

 bacteria feed on the carbohydrates, and by an oxidising pro- 

 cess fix nitrogen. The bacterial activity produces acids, for 

 which it is desirable to find a base, hence the great value of 

 lime on many soils. 



Diastase, a fungous product which has the power of con- 

 verting starch into sugar. 



Invertase, a fungous product or enzyme which has the 

 power of splitting cane sugar and converting it into simpler 

 forms. 



Cytase, a fungous product which can dissolve cellulose. 



Peptose, an enzyme which converts proteids into peptones. 



Lipose, an enzyme which breaks up fatty oils. 



Oxydase, an enzyme which effects oxidation and causes 

 change of colour. 



Hymenium. — " The base of an aecidial cup, formed by 

 those hyphae which produce the secidio spores." — Plowvight.
