Hello,
Nearby the find of Calycina claroflava on Populus x canescens (by Rene Hoogenboom) I found this nice hyphomycete.
Could this be Troposporella fumosum?
Greetings, Riet

Re : Troposporella fumosum? on Populus x canescens
Hi Riet
It looks close. Have you eliminated Troposporella (Helicoma) monilipes?
Do you have access to:
Goos RD (1986) A review of the anamorph genera Helicoma. Mycologia 78:744–761
Helicosporous hyphomycetes from China (2007) Fungal Diversity
Regards
Chris

Hi Chris,
I used the key on page 147 and I think I see conidiophores constricted at septa

But difficult to tell.

Re : Troposporella fumosum? on Populus x canescens
Hi Riet,
Looking at the colour and size of the conidia spirals they seem to match T. monilipes more - dark brown and 12-19µm, whereas T. fumosa are Golden Brown and 12-16. Your images here against the scale provided suggest 19-20 plus at the high end. Also not constricted and although difficult to judge without seeing T. fumosa I would expect more constriction. Probably added to the confusion!
Best wishes Tony

Hi Tony,
Thank you so much for your help/explanation! I had no idea how or what to measure.
Best wishes, Riet

Re : Troposporella fumosum => Troposporella monilipes
Hi Riet, do you happen to have any material of this to share with me? I am interested in perhaps trying to culture it if it has been air-dried, and then sequence it? Nice observations!

Re : Troposporella fumosum => Troposporella monilipes
Hi Jason,
Thank you! :-)
Got an email from Rene that he is on holiday now. I'm sure he will collect new material when he gets back.
I will email you when the material is collected, checked and dried.
Best wishes, Riet

Re : Troposporella fumosum => Troposporella monilipes
Fantastic! I hope that he is able to find more. Please air-dry the specimen so that I can attempt to culture it. Thank you and I look forward to hearing from you!
