Black balls on Ulex

The ascomata of this fungus grew on corticated wood of Ulex europaeus, making cleistothecia (apparently non-ostiolate), blackish-brown, up to 0.5 mm in diameter, erumpent, isolated or coalescent and more or less spherical. The evanescent asci are claviform, pedicellate and contain (2-3-)4 dark brown spores with an apical pore, probably also monosporic since some excessively large spores may be seen.
At the end, the contents of the ascomata are powdery and consisting of a large cluster of spores and the asci disappear.
I wonder if this fungus could be well accommodated in the monospecific genus Boothiella, although it is different from Boothiella tetraspora, with larger cylindrical asci and larger and different spores.
Many thanks in advance for your opinions.

Re : Black balls on Ulex
The spores immediately remind me of Copromyces bisporus N. Lindq. However, that species has two-spored asci and grows on dung. Maybe a related species?

Re : Black balls on Ulex
I worked on cleistothecial fungi for my Ph.D. about 50 years ago. Here is a plate I prepared for Copromyces and similar things. http://website.nbm-mnb.ca/mycologywebpages/EssaysOnFungi/Cleistothecial_Ascomycota/Cleistothecial_Ascomycota-Plate04.html. The comments are more recent.
