On Parrya macrocarpa R. Br. Camden bay, July 17, 1914, 98673. 



On Oxytropis campestris (L.) DC. var. sordida Willd. Bernard harbour, 

 August 1915, 98415. 



On Oxytropis nigrescens (Pall.) Fisch. Camden bay, July 17, 1915, 98413. 



On Campanula uniflora L. Bernard harbour, Aug. 16, 1915, 98779. 



This fine species is reported from East and West Greenland ard from Alaska. 



Pyrenophora comata (Awd. and Niessl) Sacc. 



Pleospora comata Awd. and Niessl. Transl. in Ell. and Evrht. N. Am. Pyr.,

On Oxyria digyna (L.) Hill. Cape Bathurst, July, 1916, 98149. 



On leaves of Dodecatheon frigidum Cham, and Schlecht. Herschel island, 

 August, 1914, 99825. 



Pyrenophora paucitricha (Fuckl.) Berl. and Vogl. 



On Papaver nudicaule L. Kogluktualuk river, July 19, 1915, J. R. Cox 

 and J. J. O'Neill, 97852. 



Associated with a Phoma on Oxytropis Eoaldi Ostf. Bernard harbour, 

 August 1, 1915, 98406. 



The perithecia are here crowned by a group of septate, brown bristles, 

 90-150 X 5-6 IX. Lind comments on the variation in the size of the sporidia in 

 this species as found in Greenland collections. The smaller sizes are near 27 x 11 fi 

 and the largest reach 45 x 22 fi. 



On Papaver many of the sporidia were 3-septate but not muriform. In 

 mature asci longitudinal as well as transverse septa were evident. 



Pyrenophora sp. 



On Erigeron compositus Pursh. Victoria island, March 29, 1916. 

 Ths is different from the foregoing but not in condition to determine. 



Teichospora sp. 



On a fragment of bark of one of the willows bearing Scleroderris fuliginosa 

 (Fr.). Sadlerochit river, November, 1913. This seems to be related to T. 

 papulosa E. and E., and to T. patellarioides Sacc. Sporidia 5-septate, muriform, 

 dark-brown. The perithecia bear short, basal, brown hyphae. 



The foregoing enumeration includes thirty sphaeriaceous species inhabiting 

 phanerogams most of which grew in the country around Bernard harbour. 



Captain Fielden and H. C. Hart collected fungi on the Nares expedition. 

 These were determined by the Rev. M. J. Berkeley who found only three sphae- 

 riaceous species, indeed only two, for one, a Chaetomium, grew on a damp surface 

 in the cabin of the Alert and is cosmopolitan. The other two were Venturia 

 Myrtilli Cke. on Cassiope and Mycosphaerella lineolata (Desm.) on a grass. 



Mr. H. G. Simmons, connected with the second Norwegian expedition on 

 the Fram, collected nine of the foregoing species on Ellesmere island, viz.: 



Pleospora herbarum (Pers.). On Arnica alpina, Taraxacum hyparcticum, 

 Campanula uniflora, Armeria sibirica, Pedicularis capitata, P lanata, 

 Chamaenerium latifolium, Potentilla rubricaulis, Saxifraga aizoides, S. 

 cernua, S. groenlandica, S. Hirculus, S. nivalis, Draba nivalis, D. flad- 

 nizensis, Papaver radicatum, Ranunculus sulphureus, R. affinis, Melan- 

 dryum affine, Stellaria longipes, Alsine verna, Oxyria digyna. 



Pleospora Drabae Schroet. On Draba alpina. 



Pleospora vulgaris Niessl. On Potentilla emarginata, Cystopterisfragilis, and 

 Lycopodium Selago.
