XXVIII. On the fructification of certain Sphæriaceous Fungi

The author refers to the recent inquiries into the diversities of form existing in the reproductive organs of Fungi, and notices the physiological importance of the results, and the probable future effect upon systematic arrangement. Two different classes of Sphæriaceous Fungi are then noticed in detail, in the former of which the different forms of fruit produced are essentially distinct, whilst in the latter the fruit is modified so as to assume a form materially different from the normal form.
