      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:

        Cheers

          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.

              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 biochemical 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.

              Considering the 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.

                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

                  This species has just turned up again in Yorkshire. Collected from a small streamlet in the garden at RHS Harlow Carr in Harrogate last week. My photo is not particularly good but all the appendages were there!

                  Interestingly the species was seen in NW Portugal during work done in 2001-2002. See Pascoal (2005 ) Aquatic hyphomycete diversity in streams of Northwest

                  Portugal. Fungal Diversity 19: 109-128
