On the inner bark of Crataegus

Enrique Rubio, 14-01-2014 21:30

Hi to all

My friend F.J. Balda sent to me these gregarious, very small, turbinate, white to amber apothecia growing on the inner bark of Crataegus together with Orbilia xanthoguttulata.

I don't know a good genus for this fungus that maybe reminds me the callorioid fungi. Asci IKI negative, with croziers. Paraphyses with clavate tips and without Vb's. Excipulum with + or - roundish hyaline cells. Marginal 'hairs' hyaline, clavate, smooth, with any content.

Have you any idea?

Many thanks again

Re : On the inner bark of Crataegus

I think it is Cistella chlorosticta which I found with warted as well as smooth hairs.

Hi Erique and Zotto,

Is Cistella mali not another possibility taking into account spore length and substrate?

Re : On the inner bark of Crataegus

Yes indeed, Bernard, though I am not convinced that the two taxa belong to diferent species. In my folder of mali the spores are 2-3 µm wide.

So Enrique's find fits my mali in spore length and my chlorosticta in width....

Re : On the inner bark of Crataegus

Thank you Zotto and Bernard. It's a very curious Cistella species with smooth hairs!
