Calyptellopsis-like Cyathicula on moss and cones
Michel Hairaud,
14-03-2024 09:12
Voici une récolte avec des caractères typiques du genre Cyathicula (Ectal à Textura Gelatinosa, Paraphyses à vacuoles réfringentes, IKI de type Helotiaceae )
Saprotrophe sur vieux cône de Pinus sylvestris et sur mousse vivante ou morte.
Largeur des apothécies et hauteur du stipe 0,5 mm.
Apothécies blanches, voire translucides
Ectal de cellules étroites et allongées ( 20- 40 x 3-4 µm) Cellules terminales avec VBs, lisses.
Pas de cristaux
Stipe x 0,09-0,12 , légèrement élargi au sommet , mêmes cellules que l'ectal
Asques IKI bb , H+, 60-70 , Pars Sporifera 25-30
Spores 10-12 x 3,2-4 µm , guttules peu réfringentes mais OCI 3,5-4
Paraphyses x 2-3 , à VBs homogènes.
Pas d'espèce correspondante dans la monographie de Carpenter
Ne correspond pas à C. translucens Le Gal
Pas de véritable correspondance non plus dans le dossier de Zotto (Calyptellopsis ) mais cette espèce se situe manifestement dans ce groupe.
Merci pour tout avis
Amitiés. Michel

Re : Calyptellopsis-like Cyathicula on moss and cones
Cher Michel
you mean 0.09-0.12 mm for the stipe.
The apical ring is Calycina-like and also the elongated VBs forbid Calyptellopsis but fit Calycina, as does the oblita-excipulum.
Calycina conorum is never such long-stalked, but I have no idea besides this.

Re : Calyptellopsis-like Cyathicula on moss and cones
Merci cher Zotto,
I did hesitate with the IKI reaction type. Not as clear as usual to me.
So I ignored the possibility of a Calycina sp. thouth the typical paraphyses VBs. And of course gelatinized ectall is also possible there.
I did not observe any reddening of the apos due to VBs oxydation
This collection would then be close to the C. pulvinata or subtilis group
Or would Allophyllaria be another possibility ?

Re : Calyptellopsis-like Cyathicula on moss and cones
Allophylaria is close to Calycina but usually has hemiamyloid apical rings and larger spores, also shorter VBs.
