Glossary 



Acervulus (acervuli). Open, saucer-shaped, asexual fruiting-body. 

 .^ciospore. One of the types of spores formed by the rust-fungi. 



iEciospores are produced in the blisters on conifers in the case 



of the bhster-rusts. The juniper and cedar rust-fungi form 



seciospores on the pomaceous host. 

 Ascospore. Sexually formed spores which are borne within a sac 



called an asous. The asci are in turn borne on .or in various 



tjfpes of fruiting-bodies. 

 Ascus (asci). Sac-like structures containing ascospores. Asci are 



borne in open or closed fruiting-bodies. Peritheeia contain asci. 

 Bacterium (bacteria). Small, microscopic plants. Plants consist 



of single cells, which may be motile. Parasitic forms cause in- 

 fectious diseases of plants and animals. 

 Basidiospore. Short lived spores borne on germ-tubes of teUospores 



in the rust-fungi. They are forcibly discharged and are carried 



by the wind. 

 Cambium. Region of growth in a woody stem or root, at which wood 



is formed on the inside and bark on the outside. 

 Canker. A dead area of bark. 

 Chlorophyl. The green coloring material produced in the leaves of 



the higher plants. Chlorophyl is instrumental in making starch 



from carbon dioxide gas and water.
