 pentamera Karst. Sacc. Syllog. II, p. 266. 



This fine species, which is easily recognized, and which seems 

 to be common in this neighbourhood, was first described by P. A. 

 Karsten (Fungi in insulis Spitsbergen et Beeren Eiland. Öfv. of Kgl. 

 SV, Vet. Ak. Förh. 1872 No. 2) as a Pleospora; the spores have, however, 

 as described and figured by Berlese (Icônes Fungorum vol. II, 

 p. 31 & tab. XLVI), all their cells in the same plane, and accordingly 

 it is a Clathrospora. When seen from the front, the sporidia are 

 oblong pear-shaped with four cross-walls and one longitudinal wall 

 in the three middle compartments without any narrowing, when 

 seen from the side the crosswalls only are visible, not the longitu- 

 dinal wall, and then they have distinct narrowings. Their colour is 

 most frequently yellow like honey, but may grow almost black with 

 age. I most frequently found the sporidia somewhat larger than 

 stated by Karsten, viz. 29— 36^^ long, 15 — 17/« broad and 9 — 12 /< 

 thick.
