Trichoconis

Hyphae of Trichoconis schnifferulae, from Deighton & Pirozynski (1972).

Belongs within: Fungi.

Trichoconis is an anamorphic genus of fungi that are hyperparasites on other plant-parasitic fungi.

Characters (from Deighton & Pirozynski 1972): Mycelial hyphae superficial, repent, septate, branched, smooth, colourless or almost so. Conidiophores well-developed, arising as lateral branches of the mycelial hyphae, simple or branched, septate or continuous, smooth, polyblastic, sympodial, denticulate. Denticles are narrow tubular separating cells cut off from conidiophore by basal thin septum or from conidium by another septum, cylindric or, in a few species, slightly conoid or obconoid, conidium shed by fracture of separating cell, sometimes about middle, sometimes near base and sometimes nearer or very close to base of conidium which leaves a longer or shorter tubular open-ended denticle attached to conidiophore and usually a longer or shorter portion attached to base of conidium; in some species (e.g Trichoconis angustispora and T. africana) the separating cell breaks so close to the base of the conidium that only a minute frill remains; in T. sigmoidea even this frill cannot be seen though old persistent fractured separating cels on conidiophore are open-ended denticles. Conidia more or less fusiform or filiform, colourless or nearly so, rarely (e.g. T. viridula) very dilute olivaceous, smooth, 1- to several-septate.
