Hemisphaeriale on Tilia leaves

Enrique Rubio, 21-05-2018 17:28

Hi again
Ascomata (thyriothecia) small (100-125 micr. in diam.), ostiolate, growing on overwintered leaves of Tilia cordata at 1000 m of altitude.
Their walls with textura subepidermoidea of irregular cells covered by brownish mycelium. Asci bitunicate. Hamathecium present. Ascospores with a small apical hyaline germ pore.
Could yo help me?
Many thanks again
Enrique
