Ove Rostrup: Bidrag til Danmarks Svampeflora. I. 55 



Helieoou polituluiu (Schulzer) Lindau. On downfallen fruits of Acer 

 pseud opiat a nus. 



Stysanus verrucosus Oud. On dead seeds of Finns and Dactylis in 

 germinating apparatus. Is without doubt a good species what GrUÉGUEN 

 doubts. 



Triglyphium album Fres. On bark of Quercus robur. Fig. 43 p. 51. 



Stephanoma italicum (Speg.) Sacc. et Trav. On fruits of Quercus 

 robur. 



Selerotium mucor. This by Tode in 1790 described fungus I believe 

 to have found again in room-cultures on stalks of Equisetum jluviatile and 

 on fruits of Hordeum and Alnus. t. Ill, fig. 23 and 24. 



Further are to be mentioned: 



Enipusa Fresenii Now. Numerous Aphis papaveris entirely full of 

 resting-spores. 



Entomophthora sphaerosperma Fres. An epidemic on imago of Agriotes 

 lineatus in the vicinity of Aarhus. 



Microascus Schumacher! (Hans.)! Microascus sordidus Zuk. is syno- 

 nymous with the Sphaerella Schumacheri described by E. Chr. Hansen 

 in 1876. 



Calonectria belonospora Schroet. A double-ascus is shown in fig. 6 

 p. 8. 



Claviceps purpurea (Fr.) Tul. Some experiments with sclerotia origin- 

 ating from different species showed that some (from Secale, Molinia coe- 

 rulea, Arundo phrag mites) all germinated the first spring after sowing in 

 autumn, while of others (from Phalaris arundinacea, Festuca gigantea, 

 Dactylis glomerata) there were some which did not germinate till the second 

 spring after sowing. It is to be observed that the sclerotia had been exposed 

 to the influence of the frost during the winter. Regarding the number of 

 sporophores on the sclerotia of the different species tab. 2 p. 9 gives in- 

 formation. 



Rehmiellopsis abietis (E.Rostr.)! In 1902 E. Rostrup described under 

 the name Sphaerella abietis a fungus on leaves of Abies spp., a species which 

 was described again in 1910 by Bubäk and Kabåt under the name of 

 Rehmiellopsis bohemica. As in having more than 8 spores in every ascus 

 it differs from the genus Sphaerella it may be right to base a new genus 

 on it, but the specific name »abietis« it must retain. 



Rhopographiis i'ilicinus (Fr.) Nke. The spores of this species are com- 

 monly stated to have »3 (rarely 5)« septa. In one locality the condition was 

 found to be considerably different from the normal state, as only 62 p.ct. 

 of the spores had 3 septa while 7 p.ct. had 4, 18 p.ct. 5, 7 p.ct. 6 and 6 p.ct.
