Hi Chris,

do you have pictures of the conidiophores?
It could be Rhodesia subtecta (see attached description by Sutton 1980). Though described conidiomata shound be more inconspicuous and pale brown only.

Hi Martin

Thank you for looking at this for me.
I don't have any images of the conidiophores.
My concern is that the conidia of Rhodesia subtecta are rather narrow. Sutton (1980), 5-7 x 2.5; Grove (1937), 12-14 x 2 and Ellis & Ellis (1997), 5-7 x 2-3.
Also, two of the authors give peak season as July - August.
I'm make a fresh collection and see if I can provide some additional information.

Regards, Chris

I too had ruled out the Rhodesia on spore dimensions.

Chris

Hi Chris,
Despite the spores size, Rhodesia is an acervular coelomycetes, and your specimen clearly forms pycnidia. So the genus Rhodesia is really out of the rule.
Unfortunately without "see" the conidiogenesis any attempt to identify this fungus will be a "shot in the dark", unless someone here in the forum already found it.
I recommend you to check Sutton's monograph but you really need clarify the conidiogenesis. Because there are several pycnidial coelomycetes with non septated hyaline conidia.
You can also check for any kind of extracellular appendage, like a mucilaginous sheath or cap, in the conidia (but I'm afraid your fungus has none), in this case NagRaj's monograph will be more useful.

Hi Soares

Thank you for giving some thought to this fungus. I have been through Groves, Sutton and Ellis & Ellis without success, but agree I needs some more details. I'm not familiar with NagRaj's monograph.

I tried to make a fresh collection this week but failed to find the fungus again. We have a lot of Marram here so will try again at a new site.

Regards, Chris

Hi Chris,

Here is the reference of Nag Raj's Monograph:

Nag Raj TR. 1993. Coelomycetous anamorphs with appendage-bearing conidia. Mycologue Publications: Waterloo, Canada. 1101 pp.

Good luck.

Many thanks Dartanha, I will look into it. Sorry I got your name reversed in the last message.

Best wishes, Chris

Hi Chris, in fact, I mistakenly had put my name in reverse order when I filled my profile, and thanks to you I noticed that! :)

In case you notice any kind of appendage I can try to scan the synoptic key from Nag Raj' monograph.

Hi Dartanha

There are no appendages on the first collection but I will pursue it and try to find some more material. It won't be for a few days as we are expecting 170kph winds! Isn't it possible to scan for NO appendages?

Thank you for the offer, I will hopefully come back with better details.

Chris

I sent it to your e-mail.
