i have difficulties to identify it. Spores 14-1
Operculate from Borneo

Hello,these fungi grew on a naked soil with low moss in a limestone area in East Kalimantan, on a margin of a cave in a rainforest.
Fruitbodies were sessile, distorted, up to 13 mm broad, brown with a reddish tinge,very fragile, very pale brown in fraction.
Smell little bit like a morel.
Spores 11-12,5 micrometers, globose, hyaline to pale brownish, with one guttule, ornamented with truncate warts of very different size - 1-3,5 micrometers broad, 2-4 micrometers high.
Asci 250-290 x 18-20 micrometers, cylindrical, octosporic, uniseriate, in Lugol blue in whole length.
Paraphyses straight, hyaline, septate, 5-5,5 micrometers broad, with obtuse apex up to 9 micrometers broad.
Excipulum consists of globose-angular cells up to 65 micrometers broad.
What could it be? Microscopically, it resembles me Plicaria, but macroscopically it´s completelly different.
Thanks, Zuzana

Re : Operculate from Borneo
Hello Zuzana,
I think this is a Pachyella species.
Not necessarily a yet described one ....
best regards,
Andreas

Re : Operculate from Borneo
Thank you, Andreas. "Pachyella" was a name from terrain, but I don´t know Pachyella with globose spores...

Hello,
now you know one ;-)

Hi Zuzanna,
your find reminds me to Boudiera. This genus has globose spores with warts. Also the asci are blueing.
Best, Uwe

Re : Operculate from Borneo
Hello,
that was my initial thought.
But the apothecia in Boudiera are far smaller and pulvinate, and the ascospores have spines instead of warts.
best regards,
Andreas

Re : Operculate from Borneo
Uwe, thanks for another idea. I though species of Boudiera are usually much smaller, but size is probably not crucial...

Re : Operculate from Borneo
Yes, Andreas, you are right. But Zuzana's find is an exotic one. Therefore anything is possible :-)

Re : Operculate from Borneo
Maybe Andreas is right: there exists Pachyella globispora. It has globose spores with warts. I don't have access to the paper where it is described:

Re : Operculate from Borneo
Great! However, I think mine is different. The spores of P. globispora are bigger (20-24 micrometers including the warts, which are 2 micrometers in diameter), paraphyses thinner...
Macroscopically it´s different too.

Re : Operculate from Borneo
Dear all,
seemed to be a good strike by Uwe, at a first glance...
But spore size of P. globispora is twice large.
I will sen the paper to all of you.

Martin

Re : Operculate from Borneo
Hello Zuzana,
if possible you should check by a section through the apothecium how the textura is. You write about textura globulosa, but the medulla in Pachyella is a textura intricata usually. Only the excipulum is of globose cells - and then you should see the hyphoid hairs standing vertically on the globose cells of the excipulum.
best regards and thanks for the article,
Andreas

Re : Operculate from Borneo
Hi,
Did you observe the way the asci where blueing in MLZ? diffusely all over or darker towards the apex. Yes, the excipulum should tell you the genus. It could be interesting for exploring the boundaries between Pachyella and Boudiera further. If you are interested in this you could contact me by e-mail: karen.hansen@nrm.se
Don Pfister suggested it is Ruhlandiella. That is perhaps more likely than Pachyella, also considering the substrate. Again the anatomy can tell. Then it could be a new species. Did you notice if the paraphyses was exceeding the asci?
Look at the paper: A new species of Ruhlandiella (Pezizaceae) from Italy. Mycological Progress 11: 509-513. 2012. by Lantieri, Smith and Pfister.

Re : Operculate from Borneo
Hello Andreas,
there really are the hairs consisting of few cylindrical cells rising from the globose cells of excipulum. The longest hair I saw was 205 micrometers long.
I add two photos.
But I don´t see t. intricata...

Re : Operculate from Borneo
Thank you very much, Karen, Ruhlandiella seems to be a very good idea.
Paraphyses are exceeding the asci.
The blue colour of the asci in Lugol is of the same intensity in the whole length. Young asci become ochre.
I add some more photos of spores.
There was no Eucalyptus in the locality, but my friend (a botanist) tells there could grow some other species of Myrtaceae.
Best regards,
Zuzana
