Hello again

These gregarious, semi-inmersed, single or in small groups, blackish, glabrous, roundish, 0.3-0.5 mm in diam., pseudothecia with a inconspicuous papilla not laterally flattened, where growing on a broad Salix sp. branch near to the river at 1300 m (Somiedo-Asturias).

The ascospores are hyaline and 1 septate, later greyish-brown, verrucose and secondarily septate, with no sheath or with only a thiny sheath when young. Asci clavate, bitunicate, 137-162 x 18-23, with 8 ascospores. Pseudoparaphyses cellular.

It looks like Massarina 'griseospora' JF 06255 from Fournier's Keys, or it would be Massarina macrospora (Sacc.) O.E. Erikss. & J.Z. Yue. I'd like to know your opinion.

Many thanks again
