CLASSIFICATION OP CRYPTOGAMS. 
411 
it is difficult to understand how macrospore” can ever 
have got into general use.^ But those terms are always to 
be preferred which convey to the student^s mind important 
rather than unimportant facts ; and since, in the present 
case, the sexual differentiation is far more important than the 
difference in size, I propose that the two kinds of spores 
shall in future be known as gpiospores and androspores, the 
receptacles in which they are produced as gynosporangia 
and androsporangia respectively. 
Appended is a table of the proposed classification. 
Proposed Classification of Cryptogams. 
A. Protophyta. 
a. Protomgcetes (Protophyta acliloropliyllacea). 
Schizomycetes. 
Saccharomyces. 
b. Prolophycea (Protophyta chlorophyllacea). 
Protococcaceae. 
Palmellacese. 
Scytouemeae. 
NostocaceaB.

Supplement to Protophyta. Myxomycetes. 
B. PUXGI. 
a. Zygomycetes (Zygospermeae achlorophyllaceae). 
Mucorini. 
Piptocephalidae. 
h. Oomycetes (Oospermeae achlorophyllaceae). 
Peronosporeae. 
Saprolegnieae.

c. Carpomycetes (Garpospermeae achlorophyllaceae). 
Uredineae. 
Ustilagineae. 
Basidiomycetes. 
Ascomycetes.

* The equally objectiouable term “ macrolepidoptera ” seems to have 
crept into entomological terminology.
