Leaf Spot
of arrow-arum. Irregular,
chestnut-brown spots, up to an inch in diameter,
have purplish or dark borders and are wrinkled
concentrically. Acervuli are sparse, black,
erumpent on upper side of leaf. Spores are five-
celled with three widely divergent setae.

Numerous, punctiform black fruiting bodies are
scattered over papery gray spots. The spores are
five-celled, bright olivaceous, with one to four
divergent, sometimes branched, setae, and
a straight, short pedicel. This species seems to
be a true parasite.
