140 ON REPRODUCTION IN FUNGI. 



coryli, D. dissepta and D. amaena, which are all kinds of small 

 caespitose and corticolons Peziza?. 



The Bulgaria inquinans, which, in the adult state, represents a 

 very large, deep black Peziza, is in its extreme youth an obtuse 

 tubercle, the whole mass of which is divided into ramified lobes, 

 and of very irregular form. The extremities of these lobes become 

 towards the surface of the tubercle recipients, from which escape, 

 for some time, waves either of pure spermatia, or of spermatia 

 mixed with stylospores. Both are ovoid, but the spermatia are 

 rose-coloured, or colourless, and much smaller than the stylospores, 

 which are as black as the spores of Melanconium* 



Quite a different organization is observed in Bulgaria sarcoides. 

 The unequal and sometimes branched clavules which accompany 

 its cups are covered throughout their superior part by a spermato- 

 phorous hymenium, and disseminate in very great abundance, 

 straight, very slender corpuscles (spermatia). In the early period 

 of their vegetation they are also covered with globular conidia. 

 As these ccespitose clavules are not always joined to the perfect 

 form of the Bulgaria, they have been hitherto taken for a distinct 

 species of fungus of the group of the Tremellince. {Tremella 

 sarcoides). 



We know of the cohabitation on the dead stalks of nettles of 

 Peziza fusarioides with Dacrymyces Urtica, and the orange-red 

 colour common to both. There is no doubt but that these two 

 products belong, as several mycologists have already supposed, to 

 one and the same species, of which the Dacrymyces represents the 

 spermogonia state, and the Peziza the perfect form. 



Another small Peziza which grows in autumn around Paris on 

 the dead branches of different trees, and which I would call Peziza 

 benesuada, on account of the instruction its study affords to the 

 mycologist, offers in some of its cups instead of the ordinary 

 paraphyses, which are linear, straight and simple, slender branched 

 and flexuous filaments, from which spring in great quantity very 

 fine spermatia. The cups thus gifted none the less contain numer- 

 ous fertile thecal, and can consequently be rigorously qualified as 

 hermaphrodites. They are just in the same case as the perithecia 

 of certain Lichens {Verrucaria), while in several species of 

 Pyrenomycetes, such as Polystigma rubrum, Isothea saligna, and 

 others, there is only a succession in the same recipient of spermatia 

 and thecse, the latter never coming except after the former. 



* I was wrong in saying (" Ann. des Sci. Nat.," 3rd ser., xvii., p. 84, note 2,) 

 that the small, imperfect, and scarcely coloured spores, which accompany the 

 normal spores of B. inquinans, were unfit for germinating, for I have since found 

 that these small spores germinate quite as well, and even more quickly than the 

 others.
