Aquatic hyphomycete

Post by NeilB » Sun Feb 14, 2021 12:39 pm

What appear to be conidia of Collembolispora barbata found in foam collected from a stream in Bristol at the end of January.
I've read Chris Yeates's account of the rediscovery of this species and wondered if this find is of any interest.

Hello Neil
You bet it is of interest! Definitely Collembolispora barbata. It's made my day . . . . :P
I'd be very interested in the background to the collection, either here or via PM. A paper I wrote which included the Collembolispora is now open-source, you may or may not have come across it:

Hello Chris,
many thanks for the warm welcome. The foam was collected from Brislington Brook as it passes through St Anne's Wood in south-east Bristol
shortly before joining the river Avon. The final sentence of Brislington Brook's Wikipedia entry states that "water quality remains poor with
relatively high oxygen demand", this doesn't sound too promising but things are much better than they used to be and several small man-made
waterfalls in the last mile or two of the stream's course help the oxygenation.

Despite living in this part of Bristol all my life and owning a copy of Ingold's Guide to Aquatic Hyphomycetes for the last thirty years this was
the first time I'd examined foam from a stream, this species was on the first slide I prepared.

Considering its apparent rarity I was surprised to find a photograph of a conidium in a paper published in 2015 in Fungal Ecology*, one of twenty
images of aquatic hyphomycetes showing the variety of form but not commented on further.

Best wishes, Neil. * Putting a link in a post is beyond me but the details are Biogeography of aquatic hyphomycetes: current knowledge and
future perspectives. Duarte et al. Free PDF available.

Why my post came out looking like this I don't know.
I'll have to preview everything in future.

Hello Chris,
sorry about the delay. I should say first that without your excellent pictures and identification of this species I would have
ignored it, so most of the credit is yours.

Hello Neil
Thanks for the information. I assume that the reason that the Collembolispora is figured in the Fungal Ecology paper is because one of the authors, Fernanda Cássio, was one of the original authors involved in finding and describing the fungus.
I can't help but wonder how many times in the past people may have seen this but were unable to put a name to it - I have quite a few images of "unknowns", some quite distinctive.
Cheers
Chris
