Several times we have found this Iodophanus species (pulvinate ascomata up to 1 mm) on wet dead stems of gramineae (Ammophila, Elymus), Calystegia soldanella or Tortella flavovirens on calcareous sand dunes at the north of Spain. At the field we thought this was the common Iodophanus carneus but the ascospore morphology, the spore size and the much larger callose-pectic markings at the poles (up to 1 µm)  were very different of those of I. carneus.

Iodophanus granulipolaris Kimbrough has a similar ornamentation buy it is a coprophilous species with larger ascospores 24-26 x 15-16 and longer spore markings too.

Have you some idea for this fungus?

My pics have a low quality because the ascomata have not a natural more yellowish colour. Really they are pinkish or salmon-orange, with the typical colors of most Iodophanus.

Thanks again
