Pseudombrophila ??

Ralf Dahlheuser, 08-06-2015 18:00

Hi,

I found this Asco between mosses on soil. I think, it is Pseudombrophila sp.
In the meantime, I am unsure. With van Brummelen I come to no good result. Maybe somebody can help me.

Spores (in Water) 21,3-22,2 x 12,6-14,2 µm
Asci up to 250 x 16 µm

Thanks in advance

Re : Pseudombrophila ??

Hi Ralph
This one belongs to Aleurina genus, but I don´t find a known species for it... Any wood below?
How abundant is the collection?
Cheers,
Raúl

Re : Pseudombrophila ??

Hi Raul,

thanks for your answer.

I found 5 or 6 single fruiting bodys, then i stopped to collect. They grow on earth, no wood.

Sorry, i forgot:

Apothecia = 3-5 mm

KOH negative
IKI no amyloid reaktion / weak dextrinoid

Re : Pseudombrophila ??

What about A. subvirescens, Raúl? Described in Zhang & Korf 1986, Mycotaxon 26, p. 377f.

regards,
björn

Re : Pseudombrophila ??

Hi Björn
Yes indeed, Aleurina subvirescens seems to match Ralf´s find. I discarded it because the drawing of the spores in Zhuang-Korf´s article didn´t look similar to what can be seen in Ralf´s blue cotton picture. But after your suggestion, I looked the article slowly again, and the SEM spores can agree. I attach a composition showing the figures of Aleurina subvirescens just to compare.
Saludos,
Raúl
