form between the Mucorini and the Ascomycetes, the asci being homo- 
logous to the zygospores of the Mucorini and Chsetocladiaceae. Con- 
firmation is thus afforded of the view that a portion of the Ascomycetes 
are derived from the Zygomycetes. 
Vanilla Disease.* * * § — Mr. G. Massee finds that a prevalent disease of 
Vanilla planifolia, in the Seychelles, is due to the attacks of a species 
of Hainsea on the living leaves — identical with Gloeosporium Vanillae , 
previously described from Antigua — the pycnids of which make their 
appearance on the decaying leaves. These belong to the genus Cytispora. 
If kept damp, the stromata of the Cytispora-iovm produce peritheces, in 
which no trace of an ascogone has been detected, but which contain asci, 
each containing 8 ascospores, and identical with those of Calospora. 
These ascospores, on germination, again produce the mycelial or 
Hainsea 'form. The correct name of the fungus is, therefore, Calospora 
Vanillae. 
Fungus of Intoxicating Fye.f — M. E. Prillieux has discovered the 
apotheces of Endoconidium temulentum, the fungus which imparts intoxi- 
cating properties to rye. They appear to belong to a new species of 
Peziza , which he calls P. temulenta , and the genus Endoconidium must 
be sunk in Peziza. 
Peach-blight. t — Mr. E. F. Smith has investigated the effects pro- 
duced on the peach by the destructive parasite Monilia fructigena, of 
which it appears that the conids hibernate in the diseased fruit. The 
infection takes place almost entirely through the flowers. 
Conids in the TTredine8e.§ — M. P. Vuillemin records the occurrence 
of conids in a fungus belonging to the Uredinese, Endophjllum Semper- 
vivi, parasitic on Sempervivum montanum. The conids take the place, 
more or less completely, of the teleutospores, sometimes entirely re- 
placing them. The author regards this as furnishing additional 
evidence in favour of the affinity of the Uredinese with the Protobasidio- 
mycetes or Tremellini, a view which is confirmed by an analogy which 
he points out in the structure of the mycele in the two orders. 
Fructification of the Gasteromycetes.|| — Herr H. Rehsteiner has 
investigated the structure and development of the fructification (sporo- 
phore) of a number of Fungi belonging to this order, especially of 
Hym,enogaster decorus , Hysterangium clathroides , Bhizopogon rubescens , 
Lycoperdon gemmatum , L. laxum , Bovista nigrescens , and Geaster 
fornicatus. 
In the immature fructification of Hymenogaster the following distinct 
parts are to be detected, — the peridiura, characterized by the dense 
interweaving of its hyph© ; an interior looser primordial weft, containing 
large crystals of calcium oxalate ; and the rudiment of a central glebe.
