94 MESSRS. F. CURREY AND D. HANBURY ON SCLEROTIUM STIPITATUM, 



Waring, for the Museum of the Pharmaceutical Society. PI. IX. fig. 4 represents a thin 

 section of the white inner substance of the Sclerotium, taken from near the circumference. 

 The threads are of very irregular shape, and hardly similar in any two sections ; but their 

 general nature may be seen from the figure just referred to. 



2. Fachyma Cocos, Pries. The variety of names which this remarkable substance has 

 received, renders a list of its synonyms not undesirable ; we therefore subjoin one which, 

 Avith the needful references, Avill, we believe, be found nearly, if not quite, complete.

Pine specimens of this production, received many years since from Dr. Macbride of 

 South Carolina, and described by him in the 12th volume of the ' Linnean Transactions,' 

 under the name of Lycoperdon solidum, are to be seen in the Museum of the Society ; 

 and one of the most characteristic of these specimens is represented in PL X. fig. 5. 

 PI. X. fig. 6 represents a longitudinal section of a very similar specimen, and is in- 

 teresting as exhibiting very completely the manner in which the root has been affected 

 ])y the P achy ma. Dr. Macbride states that the Fachyma originates between the wood 

 and bark of living roots, that it gradually detaches the bark, while it spreads round the 

 wood and converts it into a substance similar to itself. The present section, however, 

 exhibits an intermediate condition ; for, although the bark is detached and the Fachyma 

 interpolated between it and the Avood, a great part of the wood itself is but little affected. 

 The portion referred to by the letter a retains its natural colour and appearance ; and 

 when examined in section under the microscope, is found to consist of healthy woody 

 tissue in an almost perfect state. This portion, when looked at with a lens, or even with 

 the naked eye, may be seen to be traversed by narrow longitudinal white streaks, which 

 the microscope shows to be very similar in composition to the part marked b, next de- 

 scribed. This part (6) to the naked eye looks like wood of a very pale colour, but it 

 presents a totally different appearance under the microscope. It consists of Avhat appears 

 to be a mass of mycelium, the threads of which have forced their way through the sub- 

 stance of the wood in every direction, separating the cells and converting them into irre- 

 gularly shaped bodies of a highly refractive nature, having a good deal the appearance of
