KErRODUCTlON OF THE ASCOMYCETES.

Sepedoniim^ brown, spiny, surmounting an empty cell ; one can 
assimilate them to the chlamydospores of the Ilypomyces, and 
report them to the preceding species. Without judging the second 
question (very doubtful besides), one cannot help remarking the 
great analogy which exists between this conidiophorous form and 
the Ilypomyces. I should refer this species to Acrostalagmus 
cinnaharinus^ Corda (^Verticillium ruhertimum^ Bonorden), of which 
we have just written. 
It is to be remarked that as upon the Hypomyces the spores may 
remain at the extremity of the sterigmata, it may be that they are 
not always borne at the same point of the extremity of the fila- 
ment, or that they rest stuck by a liquid which glues them. The 
presence of the viscous liquid is to be seen more clearly character- 
ised in the spermogonia {Valsa^Diairype, Stictosphoeria^ etc.), and 
likewise in the pycnidia. It is thus that at the extremity of the 
branches of the Acrostalagmus (like the Hypomyces rosellus), for 
example, are formed some globules or capitules of spores. There 
is not any sporangium around this mass of spores, as, according to 
Corda, is represented in the British Fungi of M. Cooke, who 
considers it a Mucorine. 
This peculiar disposition, and the birth of many spores at the 
extremity of a sterigmate — a fact which can be easily observed, 
notably in the spermogones of the Triblidium quercinum —lesids, us 
to the forms in which many conidia are borne at the extremity of 
the filaments. We will consider, therefore, as representing the 
spermatiferous organs. Poly actis cmerea, Berk., a peculiar form of 
Peziza Fucheliana, according to M. de Bary. There is a great 
number of genera allied to Polyactis, and many of them are 
exceedingly curious, which ought probably to be considered in the 
same manner, but it is necessary to make a more profound study 
before deciding with certainty. 
Hypomyces asterophorus, Tub, presents a form of conidia very 
dissimilar in appearance to those of the others, but the morpho- 
logic value of which is the same ; these are filaments simulating 
the antennae of insects, and which become disarticulated in a crowd 
of small conidia. It suffices to represent the formation of the 
new spores, without the production of the contraction which 
accompanies the division ; we have thus rows of rectangular 
conidia and not a chaplet of oval spores. 
The comparison of the stylospores would give rise to some very 
interesting remarks, and we see, by the species which have just 
been passed in review, the difference which may be offered finally 
by homologous organs, and which really represent the spermati- 
terous apparatus. 
The analogy with the preceding genera will probably allow us to 
range not far off from the Acrostalagmus and Verticillium the 
curious Gonytrichum ccesium, Corda, and not far off still from these 
species the Cylindrodendrum album, Bonorden; the remarkable 
Ceratocladium microspermum, Corda, is analogous to it, according
