Incrucipulum? on Vaccinium leaves
Marja Pennanen, 27-07-2017 13:11
Hello forum,

sorry about the poor quality of photos.

These about 0,3 mm wide light ones grow on Vaccinium uliginosum leaves and seem to have grey hairs. On the same leaf grows something even smaller, but I have not yet studied them.

The spores are about 6x2, asci 40x4 and paraphyses are lanceolate and exceeds the asci about 20 micrometers.

The hairs are nultiseptate, have crystals and become ligter to the top, up to 90x4.

I have no articles of Incrucipulum, so I can not determine these. Maybe someone here has better sources...

Re : Incrucipulum? on Vaccinium leaves
I think there is an Incrucipulum species on Vaccinium, I. virtembergense. I think it was described by Matheis from a bog in the Black Forest, Baden-Wuerttemberg.

I do not have the paper just now (not at home), so I can only guess if the micros could fit.


Best regards from Lothar

Re : Incrucipulum? on Vaccinium leaves
Hi Lothar,

thank you for the answer. I have found I. virtembergense on Vaccinium leaves. It was white and the microscophy was bigger. I asked this because this is not the same.

Hi Marja
I do not think it is Incrucipulum. But the photos should be more sharp. The hairs are surely warted, i assume. Can you exclude a Brunnipila? That would be my first idea. Are the septa denser towards hair apex or more distanct?

Re : Incrucipulum? on Vaccinium leaves
Hi Zotto,

thank you.
The crystals leaded me to a poor path in determination. The colour is a bit odd, but this is propably B. fuscenscens, which I have found ealier on Vaccinium leaves.
