theless his names are useful in this case, being really graphic, and the great Labour aud research evidenced 

 by the tables of syuonyras make us regret that his ability to draw up a valuable work was not differently 

 exerted. Some of his figures of the various forms of " Oreille s des arhrcs" are very good; his Come 

 d' Abondance is certainly our tarragon-scented A. eiwsmiis, and he considers it identical with A. aroinaticiis 

 of ScopoH, which is probably correct, but we have not verified this synonym. It is always a spring pro- 

 duction, while A. ostreatus is as invariably autumnal. 



It is impossible to guess what mistakes maij he made in the attempt to discriminate any given Agaric ; 

 therefore we must content ourselves with pointing out such as have been. In the case of A. euosmus we 

 have akeady done it. A. drijbim has likewise been taken for A. osireattis ; this is a rare species, and we 

 shall shortly place good portraits before the student, but in the meantime may observe that it has at first 

 a universal veil, the remains of which form soft brown scales on the pileus, and hang in white fragments 

 from the margin ; the flesh turns yellow \Ahen bruised, which A. oslreafus never does, while the latter, being 

 destitute of a veil, has the pileus quite smooth, shining, and satiny when dry. Ar/arkns iilmarhis has 

 emarginate giUs. Agaricus palmatus is gluey, so that the mass is fastened together by the sticky substance, 

 whereas A. ostreatus, though of rather a clammy texture when moist, is never viscid. In Agaricns salignus 

 the gills do not run down the stem and the concavity is the other way, the under-surface being convex. 



Various trees are cited as jiroducing A. ostreatus, but our experience confines it to the apple, a wood 

 apparently not favourable to fungus growths in general. AVhether, in many of the cases in which other 

 trees have produced " ears," those supposed to be A. ostreatus were really something else, we cannot posi- 

 tively decide, but may be allowed to suspect ; little danger, however, is to be dreaded from mistake, for the 

 greater number of this class are innoxious. Persoon recommends all mentioned above as similar in quality 

 to the genuine fungus. Vittadini advises boiling A. ostreatus in water to soften its substance before 

 further proceedings, and then to use only young ones. Most assuredly the whole of this section are 

 indigestible.
