Hello, for the first time I've collected a Mollis
Are these two different ascomycetes ?

Re : Are these two different ascomycetes ?
Bonsoir Stephen ,
Not necessarily. I already noticed that young Anthracobia apothecia are urceolate with more conspicuous hairs (actually easier on such apos to observe hairs) andlook different.
You will probably confirm when they are more mature that they match the same species.
Mind you, 2 different species on a same fire place is possible...
I attach pics of a same collection
AmitiésMichel

Re : Are these two different ascomycetes ?
Hi Michael,
Yes they look more or less like yr pics, urceolate with a brown brush of apressed short hairs. I also experienced that greenish tonality in some occassions as in your 2nd pic. Anyway what species is the Anthracobia you attached ?
I follow up this collection and keep you updated. Many thanks Michel!

Re : Are these two different ascomycetes ?
I concluded in A. macrocystis in this case.
The green colour is produced by algae which often cover the apos.

Re : Are these two different ascomycetes ?
Ok, here are some data for this collection.
- Asci J-ve with bi-bulbous or uni-bulbous root, operculate
- Spores 15-16 x 6.5-7.0 um
- Paraphyses with quite swollen heads, 7um wide, some reaching 10um, their orange pigment (at upper half) is amyloid. Some paraphyses split into two heads. The subdivide at the basal one quarter.
- very short and hyaline hairs, not numerous, 30-40um (not sure if they are hairs, see pics) otherwise hairless in mature specimens. Some are wide, 12um or so.
- Ascocarps vivid orange, hairless to the naked eye, without brown mottling (tufts of hair) when mature.

Re : Are these two different ascomycetes ?
Bonsoir Stephen,
Did you also consider A. tristis ?
The cylindrical spores would match, though somehow too short

Re : Are these two different ascomycetes ?
I did but from what i see, tristis do not have very swollen paraphyses tips (macrocytis typically have), but I dont know how important this charachter is.
https://ascomycete.org/Revue/Article/Anthracobia-tristis#
The free spores are a often cylindrical but some are not that much too - very confusing. As is confusing the slightly shorter spores for all three species considered (macrocystis/tristis/nitida) all being >16 um
Yet on seeing this post:
http://www.ascofrance.com/forum/28517/anthracobia-cf-tristis
http://www.ascofrance.com/uploads/forum_file/Ficha-Anthracobia-tristis-web-0001.jpg
I see lot of similarities. Maybe tristis should be considered . I try to measure free-running spores maybe they are a bit larger.
Thanks!
I add a few more images

Re : Are these two different ascomycetes ?
Still the same idea for me. I share with you that this genus is not as easy as it may appear... (as in others -:) )Michel

Re : Are these two different ascomycetes ?
I measured a few ascospores (outside the asci) carefully and I got a slightly better result, although measurments are still on the lower range of the species.
(15.4) 15.9 - 16.4 (16.8) × (6.7) 6.9 - 7.1 (7.5) µm
Q = (2.1) 2.2 - 2.3 (2.4) ; N = 10
V = (360) 391 - 422 (476) µm3
Me = 16.2 × 7 µm ; Qe = 2.3 ; Ve = 413 µm3
Interestingly, ascomycete.org says that ascospores are 13-15 [um long] if I understand the text well. https://ascomycete.org/Revue/Article/Anthracobia-tristis
Anthracobia tristis!
