Natural size. brought out very clearly by the circumstance that there are individuals of C. eancellatus, in which the bars of the lattice-work, even in the ripe compound sporo- phore, are excessively broad and the interstices only narrow slits ; here therefore the receptaculum is a hollow body only slightly perforated. The connection between Clathrus and Geaster appears to me to be still more com- pletely established by the genus Mitremyces, which is chiefly American and still far from being thoroughly known. But I do not attempt to describe it here, for I have no sufficient account before me of the history of its development '- 6. A description of the genera Tulostoma, Folysaccum, and Sphaerobolus may be given here by way of appendix, because they depart in a remarkable manner from the type of the groups which we have just been considering. But no special proof is required to show that they approach very near to them and especially to the Lycoperdaceae, and in this position may be regarded as the representatives of distinct and at present small divisions which have to be co-ordinated with the others.
