ARTICLES IN JOURNALS. 45 Figures illustrating the genera are given, which, though rather diagrammatic in character, give a good idea of the structure of the plants. Separate indices are provided, one of the genera, and another of the species and synonyms. In conclusion, this volume may be recommended both to the advanced student, and to the possessor of a microscope who is anxious to find interesting and beautiful objects on which to employ it, and if such an one wishes to help on the study of mycology bj original work, the following remarks by the author, in connection with the family AscoholecB, may indicate to him in what direction it may be prosecuted : — *' The members of the present group rank among the most beautiful and interesting of the Discomycetes, and at the same time it is certain that they are more imperfectly known than those of any other family. The reason of this is on account of the extreme delicacy and minuteness of most species, many being practically nothing more than a semi-liquid point of jelly in con- sistency, and unless all the details are drawn up from the living specimen, the diagnosis is certain to be more or less imperfect. To those who have the opportunity, the present group offers an opportunity for adding vastly to our knowledge of these beautiful organisms." Cedrio Bucknall. ARTICLES IN JOURNALS.
