Hyphis roseis, purpureis v. byalinis ; pycnidiis siibglobosis, atvis, 

 atrofuligineis v. hyalinis sed nigrirostratis, irrumpentibus, 1-10-860 /i 

 long., 100-220 fji lat, ; 1-6 rostratis ; rostris 48-120 /x long., ad 

 basum et ad apicem 28-60 /u lat., versus medium rarius 112 fx lat.; 

 sporis hyalinis, ellipsoideis, 5-8' 5 fx long., 2-3'5/x lat., in cirros varios 

 roseos v. hj^alinos exsilientibus. 



Var. verus : hyphis roseis. 



Var. incoloratus : h^'phis non roseis : pycnidiis atris. 



Var. lafirostratus : hyphis non roseis ; pycnidiis atris ; rostris 

 latis. 



Yry. ni^rirostrafus : hyphis non roseis; pycnidiis hyalinis sed

Varieties from wliicli Poli/opeus j^inyureus has been obtained: — 

 Bismarck, Byford Wonder, Cardinal, Charles Ross, Christie Manson, 

 Cox's Orange Pippin, Early River Grenadier, Hanwell Souring, Hoary 

 Morning, Lane's Prince Albert, Loddington, Newton Wonder, Pott's 

 Seedling, Royal Jubilee, September Beaut}", Stirling Castle, Winter 

 Hawthornden, Winter Quarrenden, Wolf River. Fertile pycnidia 

 were found in Early River and Stirling Castle. 



N.B. — The nigrirostrate character is evident when growth takes 

 place in Crabill's medium (C. H. Crabill in Amer. Jour. Bot. ii. 

 1915).
