102 AN INTRODUCTION 



of Dillenius*. The fructification being imperfectly 

 known, no characters can be assigned for this order, 

 farther than the title, which is familiar to every one. 

 The genera are ten, distinguished into 1 . Those fur- 

 nished with a pileus, or cap, of which there are four, 

 viz. Agaricus, Boletus, Hydnum, and Phallus. 2. 

 Those that have no pileus, of which there are six, 

 viz. Clathrus, Helvella, Peziza, Clavaria, Lycoper- 

 don, and Mucor.

OF THE APPENDIX. 



BESIDES the twenty-four classes explained in the 

 preceding chapters, Linnaeus has, in his Genera 

 Plantarum, given an Appendix, which in the Ordo 

 Generum prefixed to that work, he calls the twenty- 

 fifth class. It contains the PALMAE, comprehending 

 such plants as have a spaclix and spatha. This or- 

 der contains thirteen generaj distinguished according 

 to the form of the leaf, such as fan-shaped, pinnated, 

 bipinnated, &c. The genera are Chamaerops, Bor- 

 assus, Corypha, Thrinax, Cycas, Zamia, Phoenix., 

 Elais, Areca, Elate, Cocos, Caryota, and Maurita. 



* Linnaeus tells us, he preferred the method of Dillenins 

 for the fungi, to that of Michelius: because it was plain to 

 everyone; whereas, that of Michelius, though that author 

 has thrown great light upon this tribe ? required too nice an 

 inspection.
