smoked oysterling

Resupinatus applicatus (Batsch) Gray 1821

Description:

Resupinatus applicatus, Smoked Oysterling. You really need your hand lens to admire this beautiful little fungus. It will appear to be growing upside down, with the cap attached to a dead branch (no stipe) and the gills facing you. The fruiting body is 0.5 - 1.5 cm in diameter, roundish, with minutely scalloped cap edges. It is brownish grey, with paler grey gills, which are widely spaced with shorter intermediate gills. There are only two records for Guernsey, but it is so small it has probably been overlooked. I know the name is tempting, but it is classed as inedible ( http://web.guernsey.net/~cdavid/botany/f... )

Habitat:

Derivation of name: Applicatus means "near" or "attached" or "close" and probably refers to the absence of a stipe and the appearence of the cap directly (closely) attached to the wood. Synonyms: Pleurotus applicatus Common name(s): Black jelly oyster. Phylum: Basidiomycota Order: Agaricales Family: Tricholomataceae Occurrence on wood substrate: Saprobic; scattered or in dense groups on the underside of deciduous logs; June through November. Dimensions: Caps 2-6 mm wide. Cap: Dark bluish-gray to grayish-black; dry; hairy. Gills: Arising from point of attachment; whitish at first, becoming blackish. Spore print: White. Stipe: Absent. Veil: Absent. Edibility: Unknown. Comments: These fruitbodies are very tiny and not likely to be found unless the undersides of logs are searched ( http://www.messiah.edu/Oakes/fungi_on_wo... )

Notes:

Resupinatus applicatus, commonly known as the smoked oysterling or the black jelly oyster, is a species of fungus in the family Tricholomataceae, and the type species of the genus Resupinatus. First described in 1786 as Agaricus applicatus by August Johann Georg Karl Batsch,[1] it was transferred to Resupinatus by Samuel Frederick Gray in 1821 ( http://www.mycobank.org/MycoTaxo.aspx?Li... ), ( http://www.soortenbank.nl/soorten.php?so... )

Great pics! With the black afro on the back of the cap where it attaches to the substrate, I'm willing to be that's actually Resupinatus trichotis.
