LICHALP

Polyblastia antonii Zahlbr.

Lichenised. Poorly known taxon.

Substrate: calciferous rocks

Altitudinal distribution: montane belt (potential vegetation: deciduous forests dominated by Fagus sylvatica and closed coniferous forests with Picea abies)

Note: a species described as an endolithic calcicolous lichen, but the minute ascomata, said to be similar to those of Halospora deminuta and containing 8-spored asci with muriform brown ascospores, could be those of a lichenicolous fungus (Merismatium?); only known from the locus classicus in the Eastern Alps (Austria).
