Note on Marasmius cauticinalis. David Paul. 345 



Fungus, calls it Ag. {Coll.) caulicinalis Bull., adding: "Denuo 

 recepi nomen Bulliardi, cujus icon accurata." So Krok and Alm- 

 quist in their Svcnsk Flora for Skolor, Stockholm, 1907, 11, 248, 

 call this Fungus Mar. caulicinalis, notwithstanding the fact that 

 all Swedish botanists hold Fries and his nomenclature in supreme 

 honour and reverence. Also, the Flore des Champignons super, 

 de France describes the Fungus under the name of Mar. cauli- 

 cinalis Bull. 



Originally, then, the specific name cauticinalis was not ap- 

 plied by any one, not even by Fries, to either of these Fungi. 

 It cannot be said that he introduced the new spelling to avoid 

 confusion, for from the outset he had named the one Fungus, 

 Ag. [Coll.) stipitarius, and no confusion would have been caused 

 by retaining the specific name caulicinalis for the other. It is 

 possible that the change from / to / arose from inadvertence on 

 Fries' part, or from an uncorrected printer's error. One can only 

 conjecture. At any rate it would appear to the writer that, 

 while the specific name stipitaria Fr. is retained for the Collybia 

 of Bulliard*, the Marasmius of Sowerby and Swartz should have 

 the name caulicinalis restored to it in accordance with the Inter- 

 national Rules for naming Fungi. 



It only remains to be said that caulicinalis is a well-chosen 

 name to indicate the habitat of either Fungus, whereas in re- 

 gard to neither of them has cauticinalis any point or significance. 

 The former means "growing on stalks, stems, straws or such- 

 like," and the latter "growing on or among rocks." While al- 

 most any Fungus may be found growing near rocks it is hardly 

 possible to think that Fries, so admirable in his selection of 

 specific names, could have deliberately chosen cauticinalis for 

 either Fungus. 



* Dr Paul is in error in assuming that the Agaricus caulicinalis Bull, is now 

 considered identical with the Agaricus {Collybia) stipitarius Fr. Quelet in Fl. 

 Myc. de Fr. 315 distinguishes Marasmius caulicinalis (Bull.) Quel, from Ma- 

 rasmius scabdlus (A. & S.) Quel, and makes the Agaricus stipitarius of Fries 

 synonymous with the latter. I have also set out the distinctions between these 

 two species in my definition of Crinipellis caulicinalis (Bull.) Rea in Trans. 

 Brit. Myc. Soc. v, 436. C.R.
