Lichenized and lichenicolous fungi on Porto Santo  
 

Acarospora lavicola J. Steiner - On volcanic rock. The only yellow Acarospora observed. It may belong to A. microcarpa because the host, Diploschistes, is common on the island, but it was absent from the collecting spot, so that we assume that the material belongs to the most similar, non-parasitic species. Ascospores ca. 4x2.2, 3.5x2.2, 3.2x2.2 mu.
