Descripción

Common in marginal turf overlying peaty sand exposed by receding water levels at "Hapupu Lagoons". Growing with Callitriche chathamensis, Limosella australis, Potamogeton cheesemanii, Lilaeopsis novae-zelandiae, Myriophyllum triphyllum, Triglochin striata and Isolepis basilaris.

Crassula sinclairii is a very uncommon species on the island but of course it is also very small so easily overlooked. The only populations I know of are scattered along the shoreline of Te Whanga and at "Hapupu Lagoons".

Descripción

Locally common in sandy peat fringing a shallow ephemeral wetland system known as the "Hapupu Lagoons". Places occupied are often under water for considerable times during the year.

Growing in association with Limosella australis, Callitriche chathamensis, Lilaeopsis noave-zelandiae, Crassula sinclairii, Myriophyllum triphyllum and Potamogeton cheesemanii.

This location is the only one I know of for this species on the islands (though it must be elsewhere). It was lats seen at this site in January 2006. So good to know its still there.

Possibly - a suggestion from a Slime Mold person (Carol Selter) (I had thought it might be a slime mold). Seen once. Noted on bryophyte turf amongst Sporadanthus traversii / Dracophyllum traversii in restiad / heath peat bog. Assumed fruiting bodies pinkish grey, 'worm-like' sausages, moderately firm to touch (structures up to 40 mm diameter but usually less). Associated with abundant Lichenomphalia "Otira Gorge". Specimens collected.

= Doodia australis (Parris) Parris

On limestone outcrop with mostly dead Poa chathamica within a dense Muehlenbeckia aff. australis vineland. A few plants, these were much larger during my February 2023 visit to the island and had clearly suffered from the storm events of the last year (late April - October) when much of the forested interior of the island was severely damaged. on this visit plants had put on new growth. This is the second site on the Chatham Islands where I know of this fern.

I had thought this might be a slime mold of some sort but those experts overseas I know offered no comments. I don't think these are the eggs of some invertebrate, each white sphere is c. 3-4 mm diameter, with a mucilaginous surface and slimy interior.

Associated with Stemonitis, and Nectriaceae in dxense forest - in this case on partially rotted rautini (Brachyglottis huntii) wood.

i presume it is this fungus (specimens collected and these will be forwarded to Dr Peter Johnston who described it (Johnston & Cannon 2004).

Common on the adaxial leaf surfaces of mataira (Myrsine chathamica). Noted as black glossy spots on leaves, infected areas chlorotic / yellowish, 3-6 mm diameter, more or less circular or oval, those bearing ascomata maturing black, glossy, and raised. Ostioles prominent, sunken.
