Apparently the telomorph is unknown

Have you seen this paper?

Diederich, P. & J. D. Lawrey. 2007. New lichenicolous, muscicolous, corticolous and lignicolous taxa of Burgoa s. l. and Marchandiomyces s. l. (anamorphic Basidiomycota), a new genus for Omphalina foliacea, and a catalogue and a key to the non-lichenized, bulbilliferous basidiomycetes. Mycological progress 6: 61–80.

Since these bulbil- and sclerotia-forming fungi reproduce vegetatively instead of via conidia, I wouldn’t be surprised if they have no telomorph, the same way the vast majority of vegetatively-reproducing lichens have no distinct telomorph. In the case of lichens the asexual species just occasionally produce apothecia, so they aren’t truly 100% asexual. Perhaps the same is true of Marchandiomyces corallinus and kin? I have no idea what the sexual structures would look like, though, do you? The related species Marchandiomyces aurantiacus was tranfered (in the paper cited above) to the genus Marchandiobasidium, which contains both sexual and asexual species. Maybe you’re familiar with what the sexual species in that genus look like? I would expect Marchandiomcyes spp. sexual structures to be at least roughly similar.

So, this is…

an anamorphic stage of a fungi. Is there a teleomorphic stage?

I agree, this looks like a parasite to me

Too irregular to be the apothecia of a Baeomyces or Dibaeis. Can’t really say what the host species is, though, sorry.

I was thinking Marchandiomyces corallinus but i am terriable on lichens but trying to learn
