Allophylaria clavuliformis?
Marcus Yeo, 07-10-2013 20:56
I recently found this discomycete on dead stems of Lycopus europaeus.

Apothecia are < ca 0.5 mm across; pale yellow with a short white stalk. Excipular cells are rectangular away from the margin, longer and thick-walled towards the margin (textura oblita?).

Asci are 110-130 x 7-9 µm; tip turning red in IKI.

Spores are 15-16 x 3.5-4 µm; no septa; with several large oil bodies and many smaller ones; some flattened on one side.

Paraphyses are ca 1-2 µm wide, with slightly swollen tips with conspicuous oily contents.

Because of the ascus reaction to IKI and the excipular structure, I provisionally identified it as an Allophylaria. A clavuliformis seems to be the best fit, but I have very little information on this species. I'd be grateful for any guidance.

Thanks in advance.

Marcus

Hi Marcus, 

Did you consider A. Byssacea ?
It's not rare in wet zones such as Le Marais Poitevin, and Lycopus europaeus is the most frequent substrate.

Yes I agree. Wonderful documentation!

Zotto - thank you for your help.

How does A. byssacea, which Michel mentions, differ from A. clavuliformis

Re : Allophylaria clavuliformis?
Good question!

I am unaware of a good redescription. Karsten published it  10 years after byssacea, and perhaps he thought - like me - that on dicots grows another fungus than on monocots.

I first thought the spores are wider on dicots but finally i gave up this distinction.
