Nematophagous Fungi: Guide by Philip Jacobs, BRIC-Version
Dactylaria candida (NEES) SACCARDO 1886
[ = Dactylium candidum NEES 1817 ]
[ = Dactylella candida (NEES) DE HOOG et V. OORSCHOT 1985 ]
[ = Arthrobotrys candida (NEES) SCHENK, KENDRICK & PRAMER ]
Form Genus: Dactylaria SACCARDO 1880
Form Subfamily: Hyalophragmiae
Form Family: Moniliaceae
Form Order: Moniliales (Hyphomycetes)
Form Class: Deuteromycetes (Fungi imperfecti)
(System of anamorphs
according to SACCARDO 1886)
Mycelial growth speed and density of Dactylaria candida are
comparable to Arthrobotrys dactyloides, but its mycelium is perceptibly more delicate.
The conidiophores of Dactylaria candida bear on their top groups of 5-7 multicellular,
spindle-shaped conidia whose central cell is larger than those at the base and on the tip.
Dactylaria candida develops two types of traps: 15-23 µm large non-constricting
rings on 10-35 µm long stalks, and 4-7 µm long, 3.8-6 µm broad adhesive
knobs on 4-15 µm long stalks (DRECHSLER 1937).
The knobs and rings tend to be detached by the resistance of the captured nematodes,
which does not prevent them from an infection of the prey (BARRON
1975; DOWSETT & REID 1977).
