Eutypicolous Unguiculariopsis from Somiedo
Enrique Rubio, 16-05-2013 20:37
Enrique RubioDear friends

We have found these minute (up to 0.5 mm), very densely gregarious ascomata growing on
stromata of Eutypa sp. on Fagus wood. There were hundred of fruit bodys filling
the surface of the stromata that, on the other hand, were fertil. No anamorph.


The ascomata, turbinate and attached by a narrow point,  are vinaceous brown and the hymenial surface (and the excipulum too) is very pruinose by the existence oh hooked granulate hair-like paraphyses. The excipular and marginal hairs are hyaline or subhyaline with hooked and granulate neck, whith any refringence at their walls and they arise from the
gelified and reddish brown cells of the excipulum.


The asci are 8-spored, IKI negative, croziers positive. Some ascospores seem to make
ellipsoid microconidia.


I don't know an Unguiculariopsis species with these characters. ZHUANG (1988) describes
U. parasitica and U. dimorpha as parasitic of pyrenomycetes, but their ascospores are different.


Can you help me


Thanks again

Re : Eutypicolous Unguiculariopsis from Somiedo
Hi Enrique

you once had such a species:  Unguiculariopsis, ERD-5523:
Arbeyales (Asturias), 14-IV-2012, as Unguiculariopsis. On Rosa sp. stems (on cankers) at 1000 m of altitude. The paraphyses are partially hooked as the excipular/marginal hairs.

 I never saw such large-spored Unguiculariopsis myself. The hooked paraphyses are unknown in the genus, but occur in Unguiculella. Species of that genus are more hyaline....

You can send me your pics, that would make it easier and in better resolution.

Hi Zotto. In fact Arbeyales is near from this place. You know my collections better than me!
I was searching the photos of the collection on Rosa but I don't find them.

Re : Eutypicolous Unguiculariopsis from Somiedo
I just re-examined my old collection on Rosa and I can see, under high bino magnification, that the ascomata grow on Eutypa (cf. lata) too.
I think these collections are the same thing and they are closely related with Eutypa.

Re : Eutypicolous Unguiculariopsis from Somiedo
so I will name the species U. eutypicola in my files.

OK., Zotto
A good name for the fungus. Maybe you will collect it when you arrive to Somiedo!
