THE GENERA OF MOSSES.

short definition, but appears to have described in it the 
leaves and calyptra of some Polytriclmm. Dillenius, 
who also received specimens from Monttus, detected Mi- 
CHELf s error, and, in the Historia Muscorum, added a few 
observations ; but in the Appendix to that work (p. 554.), 
we find a much fuller notice, drawn up from the plants 
transmitted by Olav. Celsius. Haller, in his " Enu» 
meratio methodica Stirpium Helvetias indigenarum," first 
bestowed on it the name of Buxbaumia, a name which 
Fabricius changed to Uippopodium, from the shape of 
the theca; but Linn^us and Schmiedel restored the one 
given by Haller. 
So far it had been considered a moss. Haller, how- 
ever, in the first edition of his Enumeratio, mentions it as 
a fungus : " Character fere Clathroidis, planta ambigens 
inter id genus plantarum, et Clavarias. Testam habet 
Clathroidis Micheliani, et spongiosum reticulum. Sed vita 
perennis, et natura durior est, at que reticulum in vacuas 
areolas non resolvitur." — Dillenius, in his Appendix, 
seems also to doubt whether it be not a fungus : " Pro 
musco faciunt textura pediculorum, color eorum et capitu- 
lorum spadiceus splendens, sed prfEcipue opercula trans- 
versim obscedentia ; fungum arguunt figura capitulorum, 
pulvis similior Bovistce, quam farina capitulorum musco- 
rum, et quod nec calyptra, nec folia uUa adsunt, sed basis 
mucida villosa. Color pediculis et capitulis erat fuscus et 
spadiceus, sed superficies non spiendebat. Villebatur pri- 
mum Musci et speciatim Lichenastri species, sed cum ex 
muscis ctustaceis seque ac herbaceis, putrcscentibus enasci 
observarem, Bovistam credidi. Qui nasceiitem videbunt, 
utrum fungus an muscus sit planta ilia a Buxbaumio pri- 
mum observata, decernere poterunt.*" — Linnaeus, in his 
Species Plantarum, did not venture to arrange it among any 
of the well known plants ; and, in the Flora Suecica, it is
