Violaceous Otidea on submediterranean situation
Enrique Rubio, 04-12-2011 13:40
Enrique RubioHi to all:

We don't know this nice Otidea species that grows on calcareous and submediterranean situation under Corylus avellana  in the north of Spain. Ascomata are 40 mm broad and 30 mm high, substipitate, split down on one side. Hymenium vivid ochraceous. Excipulum furfuraceous and lilac-violaceous. These colours quickly fading with age.
Spores 15,0-17,4 x 7,0-8,3 µm; Q =2,03-2,39. Medullary excipulum tectura intricata. Ectal excipulum angularis to prismatica with chains of 2-4 elements with incrustate and pigmentate walls that form the external furfuration.

When we collect this fungus, we think in O. caeruleopruinosa, but the color of the hymenium and the spore size are very different. We don't know O. lilacina, but maybe our species is unknow.
What do you think? 
Many thanks for your help

Hola Enrique

Supongo que habrás contemplado Otidea "subgrandis" de la Clave de Nicolas:

Otro mensaje donde hablan de ella:

Re : Violaceous Otidea on submediterranean situation
Yes, Raúl. But I have any additional information about this nom. prov. By the other hand my spores are broader than O. subgrandis.
Many thanks!

Hi, Enrique,

Is it really different from O. bufonia ? Here is a colection from Ile de Ré last W end with slightly narrower spores  We find it with intermediate colours, from greyish to violet . 
l

I can add that Ile de ré is also under a submediterranean climate

Amitiés
Michel

Hi Michel

I think this genus is very difficult. Your ascomata are similar, but the spores are smaller ....
I don't know if this difference is so important or not for the delimitation of the species.
Many thanks, Michel

Hi Enrique.
The spore shape is typical of the O. bufonia group. Although I didn't study collections with spore-width greater than 7 µm, I'm not sure this character should be retain to separate species in the bufonia complex.
The microscopic features and the special colour of the apothecia drive to O. mirabilis.
Cheers.
