before the perfect form, sometimes even several months earlier, 

 "like the autheridia of the Ferns or Equisetacea' before the 

 formation of the spore-bearing capsules of these plants." 



The occurrence of spermatia is not limited to the sections of 

 the Fungi above mentioned. In the Discomycetes, also, Tulasne 

 found them (as in Cenanyium, Tympanis, Dermatea, Peziza, 

 Stictis, Tryhlidium, Rhytisma, Hysterium, Heterosphceria, Bul- 

 garia), and in part upon the same organs vvliich bore the spori- 

 ferous asci, preceding the formation of these {Cenangium Fran- 

 gulcp, Tul.), or about simultaneous with them [Peziza benesuada, 

 Tul.j, '' perhaps representing hermaphrodite receptacles*." 



The like are met with in the Hymenomycetes (Tremellini) f- 

 Thev have here two kinds of origin. In some [TremeUa mesen- 

 terica, lletz.) they originate side by side with the basidia, at the 

 ends of the hymeuial filaments imbedded in the gelatinous mass ; 

 in others {Dacrymyces deliquescens, Dub., &c.) they are developed 

 from the multilocular spores, each cell (each chamber) producing 

 a pedicel, the end of which swells up into a globe, which sub- 

 sequently separates as a spermatium. Another portion of the 

 same spores exhibits the ordinary kind of germination — if, for 

 the sake of convenience, this expression may be permitted, — 

 such as is known of the spores of Fungi from the researches of 

 Oschatzl, Corda§, Tulasne ||, Bornet^f, Cohn**, De Barytt,&c.: 

 the cells of the spores extend out at one or more points into filiform 

 prolongations, the threads of the mycelium. These spores ex- 

 hibiting such diverse development, although they appear exactly 

 alike to our eves, are compared by Tulasne to the two kinds of 

 spores in the Lycopodiacese and Rhizocarpese 3 and he regards 

 it as fitting to apply to them the terms 'androspore^ and 'gyno- 

 spore,' which Bayrhoffer, without equal ground, had introduced 

 for the Lichens. The latter kind of formation of spermatia
