possibly Rhamphoria on an acorn of Quercus
Ethan Crenson, 27-06-2017 16:46
From Greenwood Cemetery, Brooklyn, NY, US.  On an acorn of Quercus I found tiny beaked fruiting bodies, around .25 mm.  Only a few of the beaks remained unbroken (indicated in the photos by arrows).  Inside I found a mass of what may be secondary spores, some of them however, still maintained the shape of a large ascus.  The spores are blunt cylinders around 2.5 x 1.5um.  The only near match that i have found is in Dennis, British Cup Fungi (1960) Rhamphoria pyriformis, which mentions the ascospores "budding off large numbers of broadly elliptical secondary spores about 2x1um while still within the ascus.  Mature asci are thus filled with countless very minute spores...".  However, the substrate is different and the beaks perhaps too long in my collection.  Any input would be greatly appreciated.  Thanks.

Re : possibly Rhamphoria on an acorn of Quercus
Hi Ethan,

I made a document of what I called Rhamphoria pyriforme (attached). I managed to see the budding ascospores in cresylblue medium. Please compare.

Regards
Martin
