The designation of Lichenicolous fungi would be more appropriate, but this classification does not exist in MO. It is a fungus growing on a lichen of the genus Parmotrema (the species I do not reveal, because it could fool me as has been often lately). The fruiting body consists of a stem concolor with a red orangish hat, of hard consistency. I picked up one of these fruiting bodies and examined it under a microscope. Then I took a preparation to observe the spores. These are hialine, gutullate, long, some straight, but most curved, septate, mostly with eight septa but is difficult to count the number of septa in a lot of them, with the following average dimensions:
Me = 80.1 × 6 µm ; Qe = 13 (N=20).
From all this I attach a vast collection of photographs, ending with a set of more photos of other specimens that I had previously obtained, all taken at the same tree, and from which I became aware of the existence of this fungus.
