out of topic - peculiar unripe fungus, not an ascomycete

... but likely a basidiomycete. I hope it is o.k.

Cercophora sp. on deer dung

Ethan Crenson, 29-03-2020 22:59

Hello all,

I hope everyone is safe and comfortable.

I am looking for help with a pyrenomycete growing embedded in deer dung which I collected in a New York City park on Feb. 8 and have been incubating since. I believe it is a Cercophora species, but I have very little experience with these things.

The perithecia are black and immersed in the dung, less than 1mm in diameter, with a protruding neck.

The asci are about 150-175 x 14-18µm, eight spored, with the spores clustered in a group at the center and a long "nose" featuring an apical ring at the tip. I heated the asci in cotton blue to test for the presence of a sub-apical globulus, but without a positive result. (I am not certain holding the slide for 30 seconds in a very hot toaster oven is the correct technique.)

Spores are vermiform, usually bent--a lot like Lasiosphaeria spores--hyaline, guttulate, with long mucilaginous projections. They measure (without the projections) 32-50 x 4µm. If this is Cercophora then I suppose the spores are stubbornly in their "hyaline state" not developing a swollen brown cell. Perhaps this needs more time to mature. In such a state is it possible to reach an identification as to species?

Thank you in advance for your help!

Ethan

Re : Cercophora sp. on deer dung

Hello Ethan!

Your photos lack precision to be able to pronounce with certainty; we do not distinguish the presence of a globule at the top of the asci, nor if it is warty or not. The size of the spores is close to C.anisura, but of course without any affirmation.

Michel.
