I was able to open your blogspot. As per your quiry on what kind of mushroom species you had encountered at the U.P campus? Actually, it is Termitomyces sp., a wild . You can see those kind in soil mounds, what we call "punso". The genus Termitomyces was coined from the word termite, because this mushroom grows on mounds or termite homes. I can't give you what kind of Termitomyces this is, unless otherwise you can collect a sample of this fungus. There are at least 8 species of Termitomyces in our country.
To sir Ed, thanks for the reply. I ll try to collect a sample next time I encounter one.
