I'm sorry, but the bits I cut off, have gone with the rubbish.
This growth is more like a fur and I cannot conceive that it is spore-like.
The fact is that it consumes the frond completely if let go.

I have found a brownish fungi on the underside of the leaves of my Elkhorn.
Last year I noted the same fungi when it killed off each infected leaf
commencing at the tips and working back into the plant.
The top of the leaf gets a series of brownish dots which show the complete
coverage of fungi on the underside. The fungi first appears as a shaded
area and develops into a raised growth four to five mms in height.
I have been cutting away the infected areas which seems to pull it up
short.
However, is there a spray I could use and does this fungi have a name?

thanks,

Don
