Ascomycete sp
roman vargas alberto, 19-01-2010 17:29
Hello, I found these specimens collected on a sheet of Eucalyptus sp.

Fruiting bodies of about 0.2-0.3 cm, smooth, globular to slightly disciform, white ocher color upon drying that emerged from a small star-shaped layer of shade more pale.
Collections.: Fruiting bodies on a road many Eucalyptus sp.

Assistance is appreciated in the determination.

Alberto Roman.

Re:Ascomycete sp
Hi Roman

is the fungus really 2-3 mm diam? Thsi sounds quite big. Do you have it still fresh? The characters are difficult to see in the dead state. The macro looks more like a hyphomycete, but the asci on your photo are clear. Are the young fruitbodies closed by a peridium which breaks at maturity?

Re:Ascomycete sp
Hello Zotto specimens were without magnifying glass, measuring approximately 0.1-0.2 cm the largest specimen could reach 0.3 cm, now virtually dried up and not be seen.
The rupture was widespread on all copies if not maturity or otherwise.
The collection I found in a very humid with abundant leaves of Eucalyptus and Acacia in a layer in the soil.

A greeting.
