This member of the Muoorales was first found by Schröter (1) near Baden in 1677, and again in 1879, growing on Paxillus involutus. In 1904 it was found on Gomphidius visoidus in the Peloponnese and sent to Vuillomin (2), and in 1927 Ling-Young (3) found it on Boletus soaber in the forests of the Puy do Dame. In addition, an unnamed species of Dicranophora found by Thaater on Boleti at Kittery Point, Maine, U. S. A., was briefly described by Blakeslee (4) in his classic paper of, 1904. These are the only recorded appearances of the fungus in nature, up to the present. The accounts referred to above are short and incomplete and differ on a number of, point$. Blakeslee and Ling-Young were oonoerned only with the sexual stage. Vuillemin, whose paper is the only one published on Dioranophora alone, dealt chiefly with the sporangial stage. The ohief charaoteristios of the fungus, as described by Sohröter (5), may be summarised thus. -- Protoplasm yellowish-red. Sporangia of two types, (1) large, with conical columolla, and small elliptical spores, and (2) small, with 2- or 3-pointed forked columella and 1-2 much larger reniform spores. Zy gospore spherical, chestnut-brown, smooth or with fine warts, suspensors very unequal, the one swollen, the other thread-like.
