Trichodelitschia bisporula

Joop van der LeeAfter 1,5 years of searching I found them again but this time on rabbit pellets i.s.o horse dung.

There has been a lot of discussions about this species which includes the name change by Lundqvist from T. bisporula to T. minuta without underlying documentation resulting in changing of characters.
Now T. minuta has been changed as a synonym of T. bisporula as stated in Species Fungorum so I still stick to the documentation that has been published by renowned mycologists.

The newly found species still have the same characteristics with a measured spore size of 19.0-24.0 um; a 3 part gelatinous sheath and a ring with a hyaline outer wall on top of the germ pore.

It has been called a "polar cap" by some but when you change the focus of the microscope it will bring up another view as you can see on the photos which clearly show the hyaline outer wall and its ring structure. (photo # 4&5).
Photo # 6 shows the ring released from its position. Photos 7&8 show the ring with a hyaline content underneath which is in fact the hyaline outer wall of the ring.
One can change the position by altering the focus and this wrongly visual interpretation probably caused the impression that it has a cap i.s.o. a ring.

Greetings,


Joop
