Advice on croziers in Hymenoscyphus fraxineus
Glew David, 28-07-2019 12:19
Thank you for accepting me to the site.

I am a newbie to fungal microscopy and am trying to learn the difference between Hymenoscyphus fraxineus and H. albidinus in the UK.

I know that identification of croziers confirms Hymenoscyphus fraxineus, but would  appreciate any advice to check I'm looking at the right thing! This is my first attempt and the sample was poor, but I'll try again. Thank you. David

Hi Devid!

welcome here in the forum. Your figure is clear enough to see the cozier. especially your third poic shows it clearly. The ascus base thereby is on the right.

H. albidus will be difficult to find. Best is to take old herbarium material collected before the invasion.

good luck anyway!
