Acrocladium, a synonym of Periconiella

Petrak (1949) described the genus Acrocladium (type species: A. andinum Petrak) from unidentified leaves of a liane, collected by H. Sydow in 1937 in Ecuador. He compared the genus with Stachybotrys Corda and Sterigmatobotrys Oudem. The type specimen (W) was available for study. The leaves bear several fungi with hemispherical-discoid fructifications, including Asterinella puiggarii (Speg.) Theiss., Chaetothyrina musarum (Speg.) Theiss., and Asterina cf. guaranitica Speg. The fungus described as Acrocladium andinum is hardly visible with the naked eye, but can easily be recognized under a stereo microscope. Petrak (1949) considered this fungus to be a leaf parasite, but it may be also a mycoparasite.
