Johan BoonefaesI found this unknown star form by the microscopy of the stem of Mycena speirea.
The "star" was full screen on x1000.  So estimated of 150-180mu.
Someone knows this ?  A conidiaspore ??

Re : Starform
Reminds me of Valdensia heterodoxa Peyronel, the imperfect form of Valdensinia heterodoxa. We had it once on Vaccinium-myrtillus leaves but it is not host-specific.

Regards and best wishes for the new year!

Re : Starform
Photo of trichomes produced on the underside of leaves of Hieracium sp. These become easily detached and stick to mushrooms, dung and other materials. Many plants produce these structures.
