Género ComatrichaObservador
sarahlloydDescrição
Habitat: wet eucalypt forest. Substrate: dead Clematis aristata. Description: small scattered groups of stalked globose to ovate, sporangia to 1.2 mm tall. Sporotheca globose to ovate, 0.6–0.9 mm diameter, salmon pink. Stalk: 0.4–0.5 mm long, i.e. slightly less then ½ length of sporangia, reddish brown, shiny, wider and with reticulate fibres at base. Hypothallus: conspicuous, red–yellowish brown, discoid under solitary sporangia, continuous under groups Peridium: slight iridescence in newly formed sporangia, fugacious. Columella exceeds length of sporotheca, reddish by transmitted light, longitudinally striate. Capillitium sparse, attached along length of columella, 2 µm with thickenings. Spores salmon pink in mass, pale by transmitted light. Spiny with groups of darker spines, 9–10 µm. Notes A distinctive species first observed in May 2014 on dead Clematis aristata.
Only found on dead C. aristata.

Collected from leaf litter on 'big tree' log. Stalk 1 mm; sporotheca 0.5 mm.
Capillitial tips resemble M. martinii, but spores are more like M. cornea (Poulain et al #433 & 434). Sequencing by D. Leontyev confirmed Macbrideola.

Comatricha subalpinaObservador
sarahlloydDescrição
Habitat: Closed wet eucalypt forest.
Substrate: Leaves (Acacia melanoxylon, Pomaderris apetala and Eucalypt sp.) on the ground near THE dogwood.
Description: Gregarious to scattered stalked brown sporangia 1.4–1.6 mm tall on red brown hypothallus discoid under each sporangium. Sporothecae subglobose 0.4 x 0.6 mm diameter. Peridium fugacious except for a collar at top of stipe and sometimes at the top of the sporotheca. Stem black, shiny, subulate, 0.5–0.8 mm long, red brown by transmitted light; fibrous at base. Columella Reaches nearly to apex of sporotheca, quite thick. Capillitium attached along full length of columella, tubular with short nodules at the extremities.
Spores brown in mass, lighter brown by transmitted light with distinct reticulate pattern, 6–8 µm.
