51. Rhabdospora groenlandica nom. nov. Syn: Septoria nebu- 

 losa Rostrup. Sacc. Syllog. X, p. 385. 



By Rostrup it is called Septoria nebulosa (Rostrup: Fungi 

 groenlandiae 1888 p. 575); as it is, Ьолуетег, always found on dead 

 leaves and stalks and never forms spots on living leaves, it ought 

 to be called Rhabdospora according to the common method of no- 

 menclature. The name Rhabdospora nebulosa is, however, preoccupied 

 for another fungus, Rhabdospora nebulosa (Desm.) Sacc. Syllog. Ill, 

 p. 589, so that I am obliged to find a new name for the above men- 

 tioned fungus. 



It is very common on dead leaves of the Monocotyledones. There 

 is no small difference in size between the separate sporidia, the 

 longest I measured were 28//, the shortest 13;/; still the greater 

 number are 20—22// long and 2—3// broad; their shape is always 

 that of a small crescent, spindle-shaped with both ends evenly and 

 sharply pointed; its contents are most frequently slightly granulated 

 and there are sometimes slight traces of a dissepiment in the middle. 

 The perithecies are small, their diameter 80 — 120//, they are nume- 

 rous and grouped in darkish oblong spots (see PI. X fig. 9 & 10).

52. Kellermannia cercosperma (Rostrup) Syn: Septoria cerco- 

 sperma Rostrup, Rhabdospora cercosperma (Rostrup) Sacc. Sj'llog. X, 

 p. 391, Septoria caudata, Karsten, Rhabdospora caudata (Karst.) Sacc. 

 Syllog. Ill, p. 593. 



Allescher mentions Rhabdospora caudata and Rhabdospora cer- 

 cosperma as two different species, saying: 



"Saccardo sagt bei Rhabd. cercosperma: "Videtur vix diffère a 

 Rhabd. caudata, sporulis 2—3 septatis". Dem kann ich vor- 

 läufig nicht beistimmen, da die Perithecien der vielen unter- 

 suchten Exemplare nie "superficialia" sondern von der ge- 

 schwärzten Oberhaut bedeckt, die Sporen auch viel kürzer
