These small ascomycota (1-3 mm) ere observed growing in a flower pot that hiuses a small Dougkas fir tree. The pot/tree has been kept inside my home during the previous 3 months of cold weather. The fruit bodies, spores, non-amyloid asci, and paraphyses seem to point toward genus Octospora. But, there are no signs of any moss inside the flower pot. Also seen at  https://www.inaturalist.org/observations/341818485. The micro is at 400x. Spores appear toi be smooth; some with one guttule, some with two, and some appearing to feature heterogeneous contents; 22-28 x 10-13. Asci are inamyloid ~220 microns long. 

I consulted the website octospora.de and the species Octospora gemmicola var. tetraspora looks like a possibility.

Any help would be appreciated.
