Anthracobia on burnt ground pairing with A. tristis
Stephen Martin Mifsud, 18-12-2021 09:55
Stephen Martin MifsudI have another Anthracobia under my lens which was growing on burnt ground with another Anthracobia (A. tristis). This looks like A. nitida , but again and again.... with shorter spores !


- Ascocarps bright yellowish-orange (in shade) but vivid in sunlight, hairless to the naked eye, with brown tufts of hair on the lower surface when mature, 2.5-4.5mm across, heaped over each other, sometimes with sunken hymenium 

- Asci J-ve without a specialised root/base , operculate

- Spores (13.6) 13.8 - 15.2 (15.5) × (7.6) 7.9 - 9 (9.5) µm

- Paraphyses with poorly to fairly swollen heads, 5um wide, their orange pigment (at upper half) is amyloid and takes a bluish-green colour. Very few split into two heads.

- Ectal excipulum prismatic (-globose) 20-48um across

- Brown tufts of hair at regular intervals on the abaxial surface of the cup consists of parallele rows of 4-6 broadly ellipsoid to rectangular hyphae with the terminal being slightly larger and swollen (20-25 um long). Total length of thse hairs estimated to be 70-110 um

- There seems to be true hairs with thick solid wall 1-septate, the basal part globular. Not sure if these belong to the rhizoids, Rare to find, posibly present only at the base. 80-120um long (only few examined)

Re : Anthracobia on burnt ground pairing with A. tristis
My opinion fell on Anthracobia nitidia and I am about to think that there is a form with small spores. This is not the first time.  Anthracobia  melaloma is my second choice because of the true bristly hairs unless they qualify as rhizoids.

Re : Anthracobia on burnt ground pairing with A. tristis
Stephen, would you allow us to sequence this?  And other collections of Anthracobia?

Thank you,
Amdy

Re : Anthracobia on burnt ground pairing with A. tristis
yes, I am interested, ithink like me you have a bit of doubt lurking, esp. for the small spores.  I have few more collections that I dried but they look as if they disappeared out from the substrate (in the dry state!).
