Spot-like, sooty patches on leaf-stalks, stalklets, and upper and 

 undersurface of leaflets, usually separate, occasionally run 

 together. 



Mycelium chestnut-brown and hyphiTe thick-walled, septate, 

 branched, 7 /x broad, with short, stout, ultimate l^ranchlets. 

 Appendages dark chestnut, thick-walled, rigid, erect, bluntly
