Hypomyces possibly on Suillus collinitus
Stephen Martin Mifsud, 28-02-2017 12:45
Stephen Martin MifsudHi, this is my first Hypomyces that I am researching and probably I would not be able to identify it to species level, but maybe with your help and direction I could take a learning experience and good path.  The host was under pine and I could see pores so I think that it is probably Suillus collinitus, which is very common bolete under pine trees. The parasite is now a mass of yellow spores, 12-25um wide, distinctly warted (2um wide!), globose, golden yellow. So far I have not seen any other particular structures such as ascii - are they deep inside the tisue or at this advance stage, it is useless.  

An interactive key for Hypomyces in the links of this forum is not working - a real pity!

Any help is appreciated...

My simple guess is Hypomyces chrysospermus - from here:
