A few very young fruiting bodies grew on a pine cone. I found only one fruiting body with mature spores already present. Microscopic structure and substrate similar to H. lutescens. But I don't like the content of the spores.
There are two regular drops in each. Besides, the paraphyses content in Lugol does not turn red as in H. lutescens.

In spite of such a substrate and the appearance of spores, can this collection be classified as H. lutescens ??

I recently found Hymenoscyphus epiphyllus on Alnus cones ... tomorrow I will try to insert photos.
Everything indicates that you are absolutely right.
I will not post photos of the new collection but I will try to explain what aroused my uncertainty. Watching H. epiphylus always saw in ectal ex. a narrow strip of cells of an oval shape. While examining these fruiting bodies, I didn't notice such cells, but probably due to the very young age of the fruiting bodies? Also, the dimensions of the spores are quite small for this species, but as I mentioned: the fruiting bodies are very poorly mature!
Today I found another collection growing on needles and cones Picea abies.
best regards

Thank you!
