Hysterium pulicare ?
Man Myco, 17-12-2015 09:00
Man MycoHello,

I found that in an herbarium sheet, probably on Fagus sylvatica, in France, Puy-de-Dôme (63). Do any one can confirm / infirm the ID ? I'm not conviced by the general shape...

Many thanks for the help!

Re : Hysterium pulicare

Hi Remy,


although the macrofoto is not very distinctive and does not show the form of the coffee beans I think there can be no doubt because of the very unique spores.

Hi Lothar,

Many thanks for your very quick answer !
I agree that I make very poor quality picture - not sure yet if it is because of the photographer, or the material ;)

In fact, I was not sure for this ID because many herbarium sheets I am currently reviewing (for epiphytic lichens) contains this species, and most of them are more "sphaerical" that coffee bean shaped... All are from the same locality.

Cheers,

Rémy

Hi Remy,


the growth on bark of living deciduous trees is very typical for H. pulicare. But - if the ascomata are not hysterothecia, it must be something different, anyway ...


Best regards from Lothar

Hi Lothar,

Thank you for the precision ; I will try to ID other specimen in order to be sure !

Hi, Remy,
so Hysterium pulicare would have to look.
Greetings Peter.

Re : Hysterium pulicare ?
Hi everybody,

I found a new one in another herbarium sheet. The two pictures are taken on the same piece of bark... On has a coffe bean shape, and the second one not much. Is it beacause of dessication ? Or another species ?

Many thanks,

Rémy

Re : Hysterium pulicare ?

Hi Remy,


the pictures show clear hysterothecia in my opinion. Do they have the same spores (4-celled with terminal hyaline cells)? Then it ist H. pulicare.


Maybe unripe or badly developed specimens do not form the typical slit very distinctly. Peters fotos are very typical.


Regards from Lothar

Re : Hysterium pulicare ?
Hi Remy,
this goes not without microscopic examination. If the scales of the photos 1:1 with the micro, it cannot be H. pulicare, the spores would be too small there.
Greetings Peter.

Re : Hysterium pulicare ?
Hi,

some new picture from the inside. Spores are about ~20-28µm.
