Hereafter follows the group Fucciniopsis, in which spermogonia, aecidia, andteleutospores have been recognised, but not vu-edospores, sothat in this group of species the luedo stage is the two remaining groups, Micro-pucciniae includes those. RUST FUNGI—UREDINEAE 247 species in which only teleutospores are known, and these donot germinate for a long time after the foster-plant is dead;and the Lepto-pucciniae, in which also the species only possessteleutospores, but the sori are compact, and germination takesplace at once and whilst the foster-plant is living. Of course,outside of all these groups there still remain a rather largenumber of species, of uncertain place, mostly with only theteleutospores definitely known, but which it is suspected willultimately find a place in some of the foregoing groups, whentheir life-history has been ascertained. Other Didymosporousgenera are Uropyxis, which seems to be hardly genericallydistinct, in which the teleutospore is involved in a thick per-manent hyaline integument; and Diorchidium, which differschiefly from Fuccinia in the septum being vertical.
