On the other hand, propagation organs, differing from those of the sporangia and their products, belong to Mucor mucedo, which may be termed conidia. On the dung (they are rare on any other substance) these appear at the same time, or generally somewhat later, than the sporangia- bearers, and are not unlike those to the naked eye. In a more accurate examination, they appear different; a thicker, partition- less filament rises up and divides itself, generally three-forked, at the length of one millimetre, into several series of branchlets. The forked branches of the last series bear under their points, which are mostly capillary, short erect little ramuH, and these, with which the ends of the principal branches ar- ticulate on their somewhat broad tops, several spores and conidia, near one another; about fifteen to twenty are formed at the end of each little ra- mulus. The peculiarities and varia- tions which so often appear in the Fio. 32.—Small portion of Botrytia ramification need not be discussed here. After the articulation of the conidia, their bearers sink together by degrees, and are quite destroyed. The ripe conidia are round like a ball, their surface is scarcely coloured, and almost wholly smooth. These conidioid forms were at first described as a separate species under the name of Botrytis Jonesii. How, then, do they belong to the Mticor ? * That they appear grega- riously is as little proof of an original relation to one another, here as elsewhere. Attempts to prove that the conidia and spo- rangia-bearers originate on one and the same mycelium filament may possiblyhereaftersucceed. Till now this hasnot been t
