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.

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!).
