Gronidia. The course of development in the few forms mentioned above on page 238, i, is shown with certainty by our observations up to the present time to be that which is there termed simple; and almost all Lichen-fungi also are without gonidia unless we count among them the soredia, which will be described in section CXVII, as there is certainly good reason for doing; other gonidial formations are described in a few species only, as ex- ceptional cases therefore, and in these are not beyond doubt. The course of development in the larger part of the Ascomycetes with which we are acquainted, and especially in the Pyrenomycetes, is pleomorphous with copious pro- duction of gonidia of more than one form. All the gonidia are unicellular or pluricellular compound spores formed by acrogenous or intercalary abjunction, as in the ex- amples which have just been described. Anatomical investigation and observation of different portions of the development show that they usually appear as precursors of the ascocarps, whether their development comes to an end when the formation or at least the completion of these begins, or they make their first appearance before the latter but continue to develope simultaneously with them. Claviceps, which has already been described, is an excellent example of the first case,
