Charles AronHi All, 

I found this Octospora growing with liverworts and mosses while gardening. In the Octospora.de website it seems to agree closest with megapolitana but it is on clayey rather than sandy soil andthe paraphyses are not hooked. 

Octospora cf megapolitana, Refail Fields, Pentraeth, Anglesey, 4/4/25 & 6/4/25
Apothecia solitary to gregarious, margin finely downy when young. Pinkish to orange. On rather compacted, clayey soil with liverworts and mosses.
Ascospores: 22x10, 22x11, 22x10.5, 21.5x12, 24x12, 22.5x11, 22x12, 22x12, 22x12, 22x11, 22x22x11, 21x11, 23x11.5, 21x12, 24x11.5, 22x11.5, 24x12, 25x12, 20x11, 22x12, 18.5x11, 19x11, 18.5x11, 21x11, 21x12, 24.5x10.5, 23.5x12, 21x11, 21.5x12, 20.5x11, 20x12, 21x11.
18-24.5x10-12
Ascospores ellipsoid, with two guttules. With evenly spaced hemispherical warts 0.5 wide and high. Occasionally with short ridges.
Asci (x400): 90x5, 85x6, 77x5, 83x7, 80x6, 103x7, 96x6, 90x7.5, 81x6, 84x8, 95x7, 74x6.5, 75x6.5, 70x7, 69x8, 71x7.5 175-240x12.5-20
Paraphyses: 7, 5, 5, 6, 6, 7, 6, 6, 7, 8, 7, 8 8, 12. Straight to curved, septate. Filled with pale yellow guttules towards the apex.
Excipular hyphae: Densely packed, with pale orange contents. Apices with amorphous substance.
Fine excipular hairs up to about 100x10.

Best wishes, 

Charles.

Re : Octospora
Not sure how much O. bridei may vary, it reminds me of that.

Re : Octospora
Hi Zotto, 

Many thanks for your suggestion. O. bridei differs in having amazing, lemon-shaped spores. I should have mentioned that O. fissidentis also comes close and grows on clayey, shady spots like this taxon. It also has pinkish tones but doesn't appear to have excipular hairs.

Re : Octospora
Yes, yours are only fusoid, I also noticed that.

Re : Octospora
Hi again Zotto, 

Quite a coincidence but today I actually came across O. bridei in a damp, shady spot in Llangni, again on Anglesey. Wonderful ascospores! It may well be a new British record. 

Best wishes, 

Charles.

Yes, this way I know it, and I saw it only twice.
