Hi,

I'd appreciate any comments on this collection. I have not had time to make a full analysis, especially of the structure of the fruitbodies, but can provide additional information if required.

Fruitbodies whitish turning orange-brown when exposed, with slightly hairy outer surface, up to 1mm diam, 0.5mm tall.

Asci clavate, bitunicate, 8-spored, IKI (Baral's)+ blue at ascus tip with two distinct lines, 106 x 7.6-8.45.

Paraphyses with distinctive guttules near apices, 3.8 wide, as long as asci.

Ascospores egg-shaped, 10.4-11.0 x 5.3-6.4.

Host: Thuidium tamariscinum, basal stem. Isle of Wight, England.

Thanks,

George
