Disco Help required

Hi
Disco help required (and I don’t mean dancing!)

I collected this yellow discomycete from a deciduous wood with mostly Sycamore Beech, Birch and Populus. It was on a very rotten branch. At first I thought it was immature Bisporella citrina but is was not quite as bright a yellow and the paraphyses are not swollen at the ends. It is up to 1mm diameter and the fruit bodies have remained turbinate and have not flattened to a disc even after 3 days in a moist environment.

I found four spores free from asci and I measured these (not oil emersion) at:
13 x 4.4
8.7 x 4.4
10.2 x 3.5
10 x 4.3

They are smooth (if rough, very minutely) some appear slightly curved in one plane

hi Peter

three days is a rather short time with these fellows - I have sometimes struggled with Orbilia spp. (which I don't think this is for a moment) for weeks trying to get them to produce mature asci . . .

we have recently been joined on WAB by the excellent Stip Helleman (see Helotiales)

I would PM him and draw his attention to this post; there are several other Bisporella species on the British list

cheers

Chris
