Used references: Arora, Mushrooms Demystified. Only fungus I know that has radiating lines under the surface. While the surface of this obs. is not brown or black, the consistency seems to match.

Only description of Daldinia I could find referring to a “brick red” stromata (surface). Little material available from the tropics, though. This might be a species novum as well. Would need voucher collection of.

haematostroma vs. rubiginosum

I think H. rubiginosum is suppose to have globose (round) perithecia, but yours clearly has long tubular perithecia. It’s also listed as purplish-brown, rather than rusty. The size of the ascospores will really help you out, if you’ve still got material and can measure them! Take a look at Roger’s description of H. haematostroma and see what you think.

No me parece que sea Daldina, en estas fotos recientes se observa un corte del ascoma , no se observan zonas concentricas, y una sola capa estromatica roja con los peritecios negros, y bajo esta un estroma blanco, sin peritecios.

Depth or Thickness?

Seems to be either Hypoxylon or Daldinia. Both have orange-red stromata species. Key to one or the other seems to be the thickness of the sporocarp in mm. Little material collected from tropical sites. This might be a species novum as well. Would require a voucher collection.

Hard like a wood, black inside

Texture?

Is this soft like cheese, or hard like a wood?
