A year ago under this title the commoner mushrooms having purple-brown spores were presented. The present contribution, a continuation of that series, describes some gilled mushrooms that are included in the white-spored group. The white-spored agarics comprise the largest number of any of the spore groups of gilled fungi. Therefore, it has been necessary to choose the species to be illustrated. The criteria are frequency of occurrence and ease of identification. On these grounds members of the genera Russula and Lactarius, which are very common, have been excluded because of the difficulties of differentiation of species. Persons interested in these genera should consult the more elaborate trealiscs. Tricholoma seems to be rather infrequent in central Iowa and has, therefore, no representatives among those illustrated.
