A new Sistotrema species from Northern Finland, S. luteoviride is described and illustrated. The two hitherto known collections derive from Finnish Lapland and both grew on corticated Juniperus communis. The spores are very similar to those of S. citriforme, which however is a simple septate species and differs clearly by its ITS sequence.
A new Syzygosporaspecies from Finland, S. lapponicais described and illustrated. The hitherto collections derive from Finnish Lapland and the species is apparently a mycoparasite of the rare old-growth forest dwelling polypore Antrodia infirma. The new species deviates from other species in the genus in having cylindrical, slightly bent spores and having a polypore as the host.
