Hymenostilbe sp.
This possible Hymenostilbe species is growing from a wasp.  The white-tipped
growth emanating from between the head and thorax of the wasp is called a
stroma and serves a reproductive purpose (the inside of the wasp has been
consumed and it is time to move on).  The wasp was within a small cavity of a
rotting log.  The stroma grew from the wasp and then penetrated a 4-5 mm layer
of wood before emerging from the log.  Stroma is 28mm long.
The conidiospores produced by this anamorphic (asexual) fungus.
