"being always erecl. Lady Arden fdvoured mc uith 

 a fpecimen of a ciTrioiis variety, with the ikin of the 

 p'ki^s cracked into fquares, leaving white reticulations 

 between. 



I cannot help fufpefling that the following four 

 fpecies of Dr. Withering will, on matvire examination, 

 prove varieties of that now before us, viz. Umbracu- 

 hem, p. 289, ■agrejlis^ '-^vS.. gracilis^ p. 313, 2i.\\^ Jpkndens^ 

 p. 334. — For the ift fee his reference to Batfch, t. 4. 

 The 2d feems to defcribe imperfect fpecimens gathered 

 late in the feafon and in wet weather. The third ex- 

 preffes the ftate of its maturity in fine weather ; and 

 the 4th as I have found it when the gluten is dried up 

 after a dewy morning. In the early part of the feafon, 

 about Auguft, I have obferved a thick gluten on the 

 pileus at 7 in the morning, changed by 11 into a var- 

 niih, quite refplcndent in the fim, the heat of which 

 hallening the progrefs of the fimgus to maturity, the 

 gills become reddifli, and the feeds are found, as Dr. 

 Withering defcribes them, at their edges. Many Aga- 

 rics, efpecially the parafitic ones, are difpofed to have 

 long roots. 1 have found that of A. radicatus 12 inches 

 .in length, and Mr. Relhan fent a flill longer fpecmien 

 to the Linnaean Society.

■T OUND in the crevices of ftumps of trees, and other 

 damp places, growing in all directions. At firft it 

 might be taken for a group of fmall infedfs' eggs, 

 being white and nearly feflile, but it is of the con- 

 fiftence of cream. It next acquires a crimfon hue, 

 with a partial Ikin, which feparates at length, dif- 

 clofmg a woolly texture replete with fine powder.

1 HE progrefs of growth in this fpecies is fimilar to 

 the laft ; but the long form of its head, and the conti- 

 nuation of the ftalk through its woolly fubftance, are 

 fufiicient marks of diftin<5lion.
