Introduction to the study of fungi : their organography, classification, and distribution for the use of collectors . ation, and the perfection with which microscopes areconstructed will have enabledthe botanists of this age todetermine that there are noreally agamic plants—that is,without sex.

Untillatterly, however, the Lichensand Fungi seemed to form ex-ceptions to this rule, for allthe researches of phytologists could not discover in them thatduality of organs which, after having been for so long theexclusive privilege of cotyledonous plants, has since been foundto belong to nearly all cryptogams. Experience and investiga-tion of forty years have shown that Lichens and Fungi stillremain practically exceptions to the rule of sexuality. ^ Massee, British Fungi—Phycomycetes, etc. (1891), p. 166.^ Comptes liendus, vol. xxxv.

After CHAPTEK VII DICHOCARPISM By the term expressed in the heading to this chapter we intendto indicate such species of Fungi as present two distinct formsof fructification, presumably proceeding from the same mycehumor vegetative system, and hence pertaining to the same is contended that the word dimorphous would haveexpressed this, but we cannot assent, because that word vaguelydistinguishes the organism to which it is applied as havingtwo forms, which might apply to the fruit, to the carpophore,or to any other organ, whilst we desire its restriction to suchFungi only as exhibit two forms of fruit. There are a verylarge number of Fungi which might be brought under thisdesignation, and those would fall into three groups. (1) Thosewhich produce two forms of fruit from the same stroma ormycelium. (2) Those which are
