1909. No. 9. FUNGI (MICROMYCETES) COLLECT. IN ARCT. NORTH AMERICA. 13 
Mollisia graminea Karsten (71, pag. 199). Sacc. VIII, pag. 352. 
Ascis 40—50 u X Io u (immaturis); sporidiis 14 u X 2 u ellipticis, 
hyalinis, ı septatis. 
On dead leaves of Dupontia Fishert. 
Area: Finl. 
Niptera Lychnidis (Fucx.) Linp. Syn: Micropeziza Lychnidis Fuck. 
(74). Not in Sacc. Icon: Oups (85), tab. II, fig. 10. 
Ascis ellipticis, utrinque attenuatis, breve stipitatis, tenue tunicatis, 
curvulis, 8-sporis, 60 u X 12 u. Paraphysibus numerosis.  Sporidiis 
ellipticis, falcatis, hyalinis, inaequaliter bipartitis, 18—22 u X 4—5 u. 
FuckeEL has found it on the same hostplant without stating the finding- 
.place. It has not been found again during the following 35 years. The 
genus Micropeziza is in the meantime obliterated, and I must put it to the 
genus Niptera, to which it relates according to its general habitus and its 
2 celled spores. Fuckel writes: »sporidiis continuis (seu septo obscuro ?)< 
but on his figures the spores are plainly divided into two cells of un- 
equal size, as I always have found them. It is very much related to 
Niptera Agrostematis (Fuck.) REHM. 
On dead leaves of Melandrium apetalum f. arctica *'s 05. 
Fungi imperfecti. 
Phoma complanata (Tove) Desm. Sacc. III, pag. 126. 
On dead stems of Pedicularis sudetica var. lanata. July 04.

Phoma herbarum West. Sacc. Ill, pag. 133. 
Matricaria inodora +5 05. 
Area: Isl., Gr. etc. 
Sphaeronema foliicolum (Fuck) Lixp. Syn.: Ceratostoma foliicolum 
Fuck. (74, pag. 94).. Sacc. IX, pag. 483. Icon: Fuck. 74, tab. I, fig. 7. 
FuckeL has never found asci, and he deliniates only perithecia and a 
single spore. I have also most frequently found the perithecia steril, but 
in few cases I have found spores, similar to Phoma-spores. ‘According 
to its shape and occurrence I am inclined to think, it is the conidial 
stage of Hypospila groenlandica. 
On dead leaves of Salix arctica var. Brownit.
