Neobulgaria on mud?
Malcolm Greaves, 12-11-2013 16:56
Malcolm  GreavesThis group of Neobulgaria look alikes were growing on the mud of the side of a reacently excavated ditch.
The asci are blued by Meltzers and the spores are c 7.5 x 3.
Can anyone help with the id.
Thanks

Re : Neobulgaria on mud?
t is not easy with mounts in Melzer. The apical ring is different from that of Neobulgaria pura. You might have Ombrophila limosella which grows on clayey ground. I should see the spores in water and whether the oil drops are small or if there are large ones. But the spores of that species are longer than 10 µm (11-16).

The spores in water mostly show two large oil drops and average 8 x 3.8
Hope this helps

Re : Neobulgaria on mud?
Ah, this was not clear in Melzer. Then Ombrophila limosella is excluded and it could be O. lilacina. That species I saw always on wood. Maybe there are some wood remains in the mud?

Re : Neobulgaria on mud?
I dug around in the mud and there was no sign of wood of any significan size.

Looking at the key to Ombrophila  Spores less than 20µm long
3 Spore width minimum 3.5 ...(3.8)
10 Sp 7-9 µm long  (8)

11 Medulla very gelatinous Ap violet (yes and yes)

14  Ap 0.7-7mm broad (5mm largest)

leads to O violacea.

Although the microscopic details fit this is another that should be on wood.

Re : Neobulgaria on mud?
If the medulla is strongly gelatinized and crystals are present then it could be O. violacea, yes. Both is not the case in O. lilacina.
But as you say, the habitat is strange.
