Haematomma sorediatum
species of fungus
Haematomma sorediatum is a species of corticolous (bark-dwelling) crustose lichen in the family Haematommataceae. It is distinctive among its relatives for producing soredia (powdery asexual reproductive particles containing fungal and algal cells) in small, round soralia; these soredia can disperse and form new lichen bodies (thalli). It forms pale white to greyish crusts on tree bark and has been recorded in Australia and New Zealand, with scattered records in Europe and the Americas. When it produces fruiting bodies, they are bright red and stand out against the pale thallus. The species was formally described in 1982 from south-eastern Australia. Records now extend across Australasia and to scattered localities elsewhere, but it remains poorly documented in many regions.
Taxonomy
Haematomma sorediatum was described as a new species by Roderick W. Rogers in 1982 in a revision of Australia's bark-dwelling Haematomma species. The description drew on earlier herbarium specimens collected near Lakes Entrance in south-eastern Victoria in the late 1880s. At the time of publication, no 20th-century collections were known. A later note reported a Tasmanian collection made in 1981.
“Haematomma sorediatum” enters the record as species of fungus. Crown Archives preserves that source wording while asking what Haematomma, sorediatum and species can confirm, complicate or overturn.
Why this record matters
“Haematomma sorediatum” is worth following because a concise public description often conceals a longer documentary argument. Here, Haematomma, sorediatum and species provides the most credible route into that argument.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Mar 6, 2026. The linked authority identifier is Q10515820. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1982 and 1981.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
