Description: Ascomata superficial, solitary or several arising from a common mycelial pad, stipitate, up
to 14 mm high, fertile head subglobose or lobed, to 3 mm diam, pale green when fresh
(Rodway) be coming pale brown on dried specimens, totally covered with the hymenium
except where the stem is inserted in an umbilicus, stalk 1 mm thick at the base, tapering
upward, pale green fading to pale brown at the apex. Medullary excipulum a narrow band
of interwoven, hyaline hyphae up to 3 mm diam. in a gelatinous matrix and merging into
the parallel hyphae of the stem which is composed of two distinct tissues - the cortical layer
up to 100 µm thick of parallel pigmented hyphae with cells up to 40 x 10 µm, the inner
tissues of long-celled very thin walled hyaline or lightly pigmented hyphae with finely
granular contents up to 5 µm diam. The stem is covered with a dense layer of superficial,
septate hairs, simple or branched cylindrical or with inflated and contorted cells, up to 150 x
9 µm. Asci cylindrical with a long slightly tapering stalk, with 8 spores in a fascicle, the
small pore blued with iodine, 105-120 x 4-5 µm. Ascospores filiform, slightly tapering,
septate, 1-1.5 µm diam, fascicles not exceeding 70 µm in length. Single ascospores not
measured. Paraphyses cylindrical with clavate tips, 1-5 µm thick, tips to 3 µm thick, 15
µm longer than asci, simple or branched from lower third.
Notes: This species occurs on fragments of eucalyptus debris immersed in water or lying on very
wet ground and is apparently rare in Tasmania and not yet recorded in Victoria.
