Calycina subtilis or....

Post by Steve » Tue Apr 26, 2016 4:09 pm

We found this on pine needles in at Longshaw recently. It was very small and really I felt that my scope wasn't quite up to it. However, I got the following features:
Disc whitish, "folding" when dry. Approx 0.2 - 0.3mm diameter.
Stalk about 0.1mm long.
Spores approx 5 x 1.5
Asci approx 30 x 4. Microscopy was difficult as the cells didn't disperse nicely. Tips appear to blue in Meltzers (but the annoyingly blue LED light makes lots of things look blue).
"Hairs" on the outside of the cups were approx 15 x 5.

From Ellis and Ellis I found Pezizella subtilis listed for pine needles, and it fits ......just about.
But there are only 17 FRDBI records. It's now called Calycina subtilis.
I feel sure there is likely to be a much more sensible ID.
