Hello,
A recent foray in Norfolk, England found a group of small cup fungi on the sawn surface of an Ilex (holly) trunk.
Apothecia: 0.6-0.9mm diameter, short-stalked, inner surface smooth, yellow/orange, outer surface covered in brown hairs
Hairs: 90-100 x 4-4.5 mostly rough walled, septate, some with granular tips
Spores: 5.5-7 x 2-2.5 single celled
Paraphyses project up to 25um above asci (no croziers seen)

We have identified this as Neodasyscypha cerina but note that spore dimensions are a little larger than described in FTE2 and Thompson's Ascomycetes in Colour.
The cups were clustered on a bed of decaying Melanomma pulvus-pyrius; none of the apothecia were actually on the sawn wood. We can find no reference of N. cerina with another fungus in the literature but it is entirely possible that the discos were growing on a dead fungus and not parasitic on the pyrenomycete.
Any thoughts or comments would be appreciated.

That's o.k. I see in Kirk & Spooner 1984 4.5-8.5 x 2-3, Dennis 1963 5-6 x 2-2.3, and Dennis 1978 and Galan et al. 1983 4-5 x 2-2.5
