Specimens of this fungus from Denmark are already contained in Schu- macher's herbarium from the beginning of the 19th. cen- tury. Concerning its distribu- tion here and abroad see R 96 q; it chiefly affects trees growing in meagre soil or exposed to flooding (see R 88 k «, 89 k, Helms 93). Its asci and spores are ripe in April; it will just as readily attack the leaves of seedlings as those of large trees. Abies alba common. Picea excelsa very common £. inst. Tisvilde (H. M. 90 ''^^).

No doubt he was the first to realize that the disease formerly called "Schiitte" was caused by attacks of this fungus. Rostrup abietis on leaves of Picea proved thatPinus austriaca and several other excelsa (c 6. d enlarged. species were particul
