OUTLINE OF PLANT GROUPS 13 



OUTLINE OF PLANT GROUPS* 



The following is a diagram of plant groups, showing one scheme of 

 placing the bacteria, yeasts, and molds in relation to other groups. 

 Only a few of the sub-groups can be shown in such a scheme. 



Plants 



Schizophyta 

 (fission-plants) 



I Schizomycetes (fission-fungi), bacteria. 



I Schizophyceae (fission-algae), blue-green algae. 



Chlorophyceae green algae. 

 Algae Phaeophyceae brown algae. 



. Rhodophyceae red algae. 

 Characeae. 



Myxomycetes. 

 Actinomycetes 



Thallophyta 



Fungi 



Phycomycetes 



Chytridineae. 

 Zygomycetes 



Oomycetes 



(Mucors). 

 Saprolegniaceae. 



(water fungi). 

 Peronosporaceae. 



(downy mildews). 



Ascomycetes 



Imperfect Fungi, 

 Conidia only 



Basidiomycetes 



Hemiasci (Monascus). 



Protoascineae (Saccharo- 



myces, Yeasts). 

 Protodiscineae. 

 Euasci Discomycetes. 



Plectascineae (Aspergil- 

 lus, certain Penicillia) 

 Pyrenomycetinese. 

 f Penicillium, Fusarium, Alternaria.f 

 I Oidium, Cladosporium, and others. 

 Rusts. 

 Smuts. 

 Mushrooms. 



Bryophyta (mosses and liverworts). 

 Pteridophyta (ferns, etc.) 

 Spermatophyta (seed plants). 



t Ascomycetous species occur among these genera but such species are rarely met in bacteriol- 

 ogical work; many of the common species of Aspergillus lack the ascigerous form, hence are 

 classified by their conidial forms only. 



OUTLINE OF PROTOZOAL GROUPS f 



"AN OUTLINE CLASSIFICATION OF THE PROTOZOA," embracing only parasitic 

 and more especially the forms pathogenic for man and domestic animals. For 

 discussion of classification see p. 133. 



Protozoa 



Rhizopoda 



Enlamaba buccalis 



Entamasba coll 

 Entamceba Entamceba histolytica 



Entamceba mehagridis 

 Plasmodiophora { Plasmodiophora brassies.
