With large guttles at the poles averaging 5um in width. Smaller guttules present.

Growing in a humid (95%) terrarium with mixed hardwood leaves, bark, splinters, and other forest litter collected from nearby forests probably 9 weeks ago. Seems to be growing out of a very rotten chunk of wood overgrown with moss and liverwort. Primary specimen is 2cm tall, 2-3mm wide cap. Light colored gills. In photos 1 and 2 you can see a little baby popping up on its left.

Stipe seems noticeably scaly, this leads me to thinking G. paludosa may be the best match that the algorithm offered but these little brown terrarium mushrooms are so tough to ID. Maybe I'll get some spores under a microscope soon.
