It seems to be a transition form in many of its characters but it has not been investigated ontogenetically nor cytologically. In Leucogaster we have another interesting genus, perhaps even more primitive than Rhizopogon. As in R. rubescens, the cavities develop centrifugally from the ground tissue. In L. floccosus the cavities are first filled by spores borne acrogenously on short branches of zigzag hyphae, or sometimes terminally on large hyphae springing from the trama. These consititute the Leucophlebs stage which is also known in L. odoratus, L. foveolatus and L. citrinus. If these are not disseminated they disinte- grate in situ, filling the cavity with a dilute gel into which the basidia penetrate. The basidia are sometimes long pedicellate, pyriform, often with pedicels 200 to 300^1ong, and solitary in L. araneosus and L. rubescens. In other species, as those of Europe and L. citrinus of California and Australia, the basidia are short and united into compact hymenia. The. *a«*-.
