Hi,Can anyone help me with following collection on a Picea abies branch laying in a brook, and having following characteristics:
Ascomata hemispherical, superficial, gregarious, uniloculate, base 0,7-0,8x0,5-0,7 mm, 0,4-0,5 mm high, papillate, with a central pore, black.
Asci bitunicate, cyl.-clav., 8-sp., sp. 2-ser., e.g. 275x34,5 µm.
Spores fusiform, smooth, brown, 7-septate, constricted at the median septum, 4th cell largest, 89-108x19-20,5 µm, thick-walled, with a large guttule and many small ones per cell, both tips hyaline and thin-walled.
Hamathecium composed of hyaline, 1,5-2 µm diam. filaments.
Thanks for your help. Best regards,
Bernard Declercq
