Collybia Dryophila parasite?

Please try to include photos to show all parts of the fungus, eg top, stem, and gills.
Note any smells, and associated trees or plants (eg oak, birch). A spore print can be very useful.

Collybia Dryophila parasite?

Post by FungiEd » Sat Feb 16, 2019 12:32 pm

Hi, whilst going through my fungi photo collection I came across this pic. that I took a 3-4 years ago. It is of Collybia Dryophila with an unusual deformity. It looks to be parasitised. After some research I have concluded that it may be Syzygospora Mycetophila, do you think I am correct please?
I would also be interested to know if the deformity is tissue from the parasite or the host as it is not very clear from the photo.
Many thanks Ed.

Hello,

in my opinion this is without doubt a Syzygospora species parasiting a Gymnopus dryophilus s.l., but without microscopical examination one can't tell which of the species of Syzygospora it is.

best regards,
Andreas

Many thanks for confirming my suspicions Andreas, do you know if it is the host material erupting from the cap or the parasites fruiting body sitting on top of it? Thanks Ed

Hello,

as far as I know this is all host tissue, deformed like a gall by the parasite who only develops hymenial structures within the host tissue.

best regards,
Andreas
