insignificant, and the fungus in them so badly developed, that a cor- 

 rect determination is impossible. Such spots are found on leaves of 

 Prunus spinosa B. Hammershus (R 06 dd "*) and on Prunus padus F.

It is found in May— June and is most common in rainy years; Ro- 

 strup states it to have been particularly common in the gardens in the 

 year 1879.

Is closely connected with the preceding one, but still to be clearly 

 distinguished from it (R 96 o''^^); it is common in the fruits of Pru- 

 nus spinosa which become hypertrophied (Saccardo is mistaken in 

 writing "in foliis tumoris").

What Rostrup (80 a "') indicates as Exoasc. deformans is both this 

 one, Taphr. cerasi and Taphr. insititiae. It is very common on peach- 

 trees in the gardens and causes great damage; many trees die from 

 the attack of the fungus (R 90 f, 91 g, 92 o etc.).

Rostrup states (91 b ^^^) that the primary attacks take place in spring 

 from the mycelium which has hibernated in the buds. In July— Au- 

 gust the spores from them will cause secondary attacks; on the leaves 

 of Pirus; produces only rather inconspicous spots.
