The specimens I have seen do not resemble Fee's figures of the plant 

 itself, nor of the spores which he figures as having 4-5 septa, and describes as 

 with " quatrt cloitons." The spores in the Irish plant were obovate, 3-septate, 

 in size and form precisely as in A. ochracea, Duf. The Irish specimens were so 

 named by Nylander. Spores .018 mm. long, .006 mm. broad.

 convex, immarginate, internally nigricant ; spores 8, colourless, 

 oblongo-ovoid, 3-septate.
