New Zealand: on dead Phormium, leg. T. Kirk, 340 (Typus).

Apothecia scattered, superficial ; disc concave, about 0.5 mm. diameter; receptacle cup-shaped, soft and delicate, white, clothed with short white hairs; stipe slender, cylindrical, hairy, white or drying buff towards the base. Hairs cylindrical, 80-100 x 3-4 µ, tips slightly swollen to 4-6 µ and rounded, walls thin, hyaline, granulate, septa usually 3. Asci cylindric-clavate, 95 - 100 x 9-10 µ, 8-spored, pore blued by Melzer's reagent; ascospores parallel, narrowly cylindrical, curved or undulating, ends obtuse, ultimately multi-septate, 39-46 x 2 µ. Paraphyses lanceolate, 3 µ wide.

This species closely resembles D. dussii Dennis, on twigs in Guadeloupe, but in the latter the whole fungus is light yellow and the terminal cell of each hair is filled with yellow oil. Fresh collections or good field notes on fresh apothecia are desirable for comparison with the common D. apalus (Berk. & Br.) Dennis which, however, typically lacks the swollen tips to the hairs and is commonly supposed to be confined to Juncus.
