The fruit bodies appeared in a suburban garden on some well-rotted staves from an old wine barrel, so presumably on oak wood. Those staves had been left in a small heap for some years. In Photo 2 I have added a 5 mm scale bar and in Photo 3 are closer views of several fruit bodies. In Photo 4 I show some microscopic detail. I did not cut a precise cross-section of a fruit body but simply gently squashed a couple of tiny pieces under a cover slip to spread out the tissue. You see (1) some empty asci and one ascus with mature spores; (2) tissue in Melzer's solution (essential ingredient iodine), showing the amyloid (or bluing) reaction near the ascal apices; (3) some of the dark brown to blackish, polygonal cells that make up the outer layers of tissue on the lower side of the fruit body; (4) dark anchoring hyphae growing from the outer cells; (5) loose spores; (6) immature asci. The various photos in that composite image are to different scales. The spores are generally about 12 x 4 microns.
