Bryoscyphus or Roseodiscus 040125 660

Miguel Ãngel RibesGood afternoon


This small pink ascomycete, 2 mm in size, was growing on a liverwort that I cannot identify. The collection only consists of 2 apothecia.


The ectal excipulum has textura prismatica, with thin cells in the outer layer and thicker internally; towards the margin they become more elongated and thinner. The medullar excipulum has an textura intricata, with thin walls.

Paraphysis slender with only few and small VBs.


The asci have 8 biseriate spores, with croziers, IKI -, KOH + IKI -, of (117) 118.5 - 129.7 (136.4) × (8.8) 9.2 - 11.4 (12.3) µm; N = 43; Me = 124.4 × 10.6 µm in living state.


Spores are navicular with a large central nucleus, a pair of medium-sized LBs between the nucleus and the tip, and some more small ones, 1 septum in overmature state, (10,1) 12.3 - 15.7 (17.2) × (3,3) 3.7 - 4.4 (4.6) µm; Q = (2,4) 3.1 - 4 (4.6); N = 54; Me = 13.7 × 4 µm; Qe = 3.4 in living state.


With the keys I can't get to any species.


Thanks in advance for your help.

I think that Bryoscyphus must have multiguttulate paraphyses and is never pink. Much better is Roseodiscus. But I see only R. "lapponicus" and one on Bryum with inamyloid asci.

I looked for R. formosus and aff. formosus, they all have amyloid apical rings.

There are two bryophytes on your photo? One is a liverwort I assume.

Re : Bryoscyphus or Roseodiscus 040125 660
Yes, there is a moss, seen in photos 1 and 2 and the liverwort that I sent in photo 3. The apothecia were growing directly from this liverwort in photo 3.
