312 PHYSIOLOGICAL BOTANY. 



all the fish in the pond had been destroyed by this growth. 

 On examining it, I found that the difference stated to 

 exist between Aclilya and Saprolegnia is incorrect, for 

 several filaments had transverse walls, many not. 



Identity of the Mucoid and Filamentous Conferva. 

 By Dr. SCHAFFNER. Flora, 1844, p. 567 ; also Flora, 

 1845, p. 501. In an appendix to his remarks upon the 

 Mucoid Confervse, Dr. Schaffner states that this plant is 

 Byssocladium fenestrale. He also found this Byssocla- 

 dimn in the expectoration of a patient suffering from 

 pulmonary tubercle. The pulverulent crusts of Porrigo 

 leprosa, as well as those of scrofulous scald-head, also 

 consist of a variety of Byssocladium fenestrale. ' Flora/ 

 1845, p. 501. There is no doubt that many of these 

 Fungi are still imperfectly developed. How many Eld- 

 zomorphete do not consist of the thallus of Merulius 

 (Xylophagm vastator), the dry-rot ! Still more remark- 

 able are the filaments which are developed in syrup pre- 

 serves, and even in solutions of the tartrates. They must 

 be allowed to grow for a long time before we can recognise 

 them as belonging to Penicillium glaucum. I cannot 

 too strongly recommend that these Fungi should be left 

 undisturbed, so as to allow of their true fructification 

 being discovered. Hitherto, there has been much con- 

 fusion on this subject. Nothing decidedly botanical has 

 been published upon the Fungi found in fermenting 

 fluids. 



MONSTROSITIES. 



On some Abnormally-developed Leaves. By the Editor, 

 VON SCHLECHTENDAL. Bot. Zeit., 1844, p. 441, 457. 

 Contains a notice of some abnormally-developed leaves 

 which were observed; hence it does not permit of an 

 extract. 



The monstrosities described by Kirschleger would re- 

 quire to_be detailed in full. Vide ' Flora/ 1844, pp. 129,
