The stalk cells rounded at the base are also long, measuring 10-15 /j. in length and arc broad as the asci. Their wall is somewhat thinner than that of the asci. The ascospores are globose or elliptical, usually 8 in an ascus, 5/? or 4-5 x7 n. Sometimes the asci are filled up with coniaia of various sizes. On Acer purpurascens Fr. et Sav. (Jap. name Kaji-kaede). At several places about Nikko in Prov. c^himozuke. 27. Y. 1906. Alarge host tree near the Nikko-Hotel is furiously attacked ? especially the leaves of the sheltered shoots are sprinkled with a great number of diseased spots, a slight distortion often resulting. No less furiously is also affected a host tree on the road side near Umagaeshi. In diseased spots any anatomical chane*e is scarsely visible, but owing to the surface extension at these places the leaves are more or less arched towards the surface oil which the asci are produced. As to the action of the fungus upon the host the present species shows nothing peculiar as distinguishing it from ('my other Taphrina on Acer. Taking the dimension and form of the asci into consideration it stands.
