On leaves of Juniperus sabina
Enrique Rubio, 16-06-2015 20:07
Enrique Rubio

Have you some idea about this fungus growing on leaves of Juniperus sabina at 1700 m of altitude?


Ascomate are blackish, more or less sphaerical, superficial on a thin subiculum, 0.15-0.20 microns in diameter. I don't know if it is ostiolate.


The saccate asci seem to be bitunicate, 70-100 x 30-32 and contain 8, first hyaline later greenish or greenish-brown, smooth, 1-sepate, 22-31 x 9-12 ascospores, the septum near the bigger cell. Hairs or setae undulate, brownish, 1-3 septate, up to 75 x 5, walls 1-1.5 microns thick. Neither paraphyses I have seen.


THE ASCOMATA WALLS STAIN PURPLE IN MELZER'S REAGENT.


I don't find this fungus on the Venturiaceae ones. Maybe a lichenized ascomycete?


Have you some idea?


Thanks in advance

Dear Enrique,

this is maybe only of minor help. Here is a checklist of fungi on Juniperus  by D.B. Belomesyatseva:
http://www.mycena.org/contents.htm
scroll down to vol. 4. I currently dont't have the time to sort it out...

Best regards

Thanks a lot, Martin


J. Linde said me this fungus of Alain Gardiennet seems to be close to the mine. Later I'll try the IKI reaction looking for a blue reaction that perhaps I didn't see by using Melzer and not IKI.

Re : On leaves of Juniperus sabina
I have not seen any apical apparatus in IKI. The blue reaction of the walls exists but its less intense...

Re : On leaves of Juniperus sabina
Last week I collected a fungus on needles of Juniperus communis that appears to be the same as Enrique's. The juniper was growing on a rock outcrop very close to an estuary in New Brunswick (45.1796° -66.3093°). Still no name for this apparently cosmopolitan species.

This is a genus Wettsteinina.
