pulvinate hyphomycete on Taxus

Hi all,
I collected a curious anamorphic fungi on bark of a dead Taxus that it looks very characteristic. It forms olivaceous brown cushions of 3-4 mm. Conidia attach through a hyaline appendix to phialides. Both conidia and phyalides are spinulose.
I do not have good literature good at hand right now.
Can anyone provide a clue?
Many thanks in advance.
Best,
Ibai.

Lo mas parecido que encuentro es
Geniculosporium serpens Chesters & Greenh., Trans. Br. mycol. Soc. 47(3): 400 (1964)
con la célula conidiógena simpodial, forma estos tipos de colonias en la madera muerta

Gracias Ángel,
el tipo de ramificación es similar, pero no encuentro especies con la superficie de las hifas rugosa. Seguiré buscando, muchas gracias.

Alors regardez un peu Conoplea?
Then, just look among Conoplea?

Re : pulvinate hyphomycete on Taxus
Dear Luc,
excellent, very much appreciated!
I have been looking the scans you sent, and also an earlier paper by Hugues (Canadian J. Bot, 1960), and I think it fits C. juniperi pretty well. Although it seems to be only known from N. America, Taxus and Juniperus are shared hosts for a number of species. It sounds a feasible option.
What it surprises me most it that Conoplea seems to be placed in the Sarcosomataceae (Pezizales).
Many thanks!
Ibai.
