Hello,I found this species a few months ago but had another look at some cones that I kept in a humid box. Frb up to 0,25mm and bright yellow. On cones of pinus sylvestris. Spores 2,5/3x1µm. The link herenunder is a previous post (3 jan 14) about the same imperfect fungi.

Anybody an idea?

Could be.... the only info I have about this species is in Ellis&Ellis. There I see more round spores. Do you have a key of this genus?
regards,
Ralph
Ralph's collection possess pleurogenous conidia (as Tubercularia), thus it is not the genus Dendrodochium which has acrogenous conidia.

Thanks for your answers. In a mail I got from Thomas, he refers to W.B. Grove in British Stem- and leaf-fungi. Coelomycetes vol. 2 (1937). Here you find the following:
Lemalis aurea Sacc. (= Catinula aurea Lev.), Dendrodochium citrinum Grove).
Excipulum lemon-yellow, urn-shaped with a spreading rim, very fragile, shining outside,
about 1 mm high and broad; margin coarsely dentate with groups of hairs. Spores
very numerous, globose, hyaline, yellow, 1,5-2 µm diam., concatenate, involved
in mucus; sporophores long, cylindrical, branched, about 0.75 µm wide, each
producing a whorl of four branches at the apex. On cones of Pinus silvestris.
& on the wood of the same. (when dry resembles Calloria chrysocoma).
regards,
Ralph
