PLATE II

^Masiill'yins = ItOO

When colouring the white Mycélium of truffle there is no possibility of detecting any kind of partition in the main filament owing to the liquid therein contained, but we observe that the secondary branches at the ends are obviously partitionned.

Fig. 12, 13 & 14. — Said thready ramifications, formed by lengthened cells, of an equal length, are branching on the ends of the main filament; sometimes they are also, in a variable number, branching on its side-strumas. Their contents are vitreous.

FiG. 14'. — Whcn perceiving in a préparation said end brandies, so very thin, near thc main filament, the différence of tliickness makes one believe them to be 2 quite différent fungi, one of them being partitionned, the olher not.

The main filament measures from 2 ^ to 4 ^r, the end branches measure froni 1/3 ;* tu 2 i^.

FiG. 15. — Said ramifications, being bereft of liqiiid in one part of their length, get flat and distorted. tlieir cells showing hère their face, there their sidc.

FiG. 16 & 17. — Hère and there are tearings in the membrane through which the contents of the cells were spilled.
