before the perfect form, sometimes even several months earlier, 

 "like the antheridia of the Ferns or Equisetacetc 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 DiscomyceteSj also, Tulasne 

 found them (as in Cenangium, Tympanis, Dermateay Peziza, 

 SticiiSy Trgblidium, Rhytisma, Hysterium, Heterosphaeriay Bul- 

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

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

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

 TuL), " perhaps representing hermaphrodite receptacles*.*' 



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

 They have here two kinds of origin. In some [Tremella mesen- 

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

 ends of the hymenial 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 

 OschatzJ, Corda§, Tulasne II, Bornet^,Cohn**,DeBarytt,&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 eyes, are compared by Tulasne to the two kinds of 

 spores in the Lycopodiacese and Rhizocarpese ; and he regards 

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

 spore,' which Bayrhofi'er, without equal ground, had introduced 

 for the Lichens. The latter kind of formation of spermatia
