Bonsoir.

Je cherche une description récente de cette espèce (donc pas Sacc., Syll. fung. (Abellini) 2: 95 (1883)), voir une iconographie.

Merci à ceux qui auraient une idée.

Hi to all,

If the common species Chaetosphaeria callimorpha is said to have a Dictypchaeta anamorph, why it was not recombined in Dictyochaeta?

Chaetosphaeria is described by the Tulasnes in 1863. Thus this genus name has priority over Dictyochaeta described by Spegazzini in 1923.

Re : Chaetosphaeria callimorpha (Montagne) Sacc.
Hi Martin,

I am sorry, Martin, but not too fast. The type species of Chaetosphaeria is Ch. innumera Berk. & Broome ex Tul. & C. Tul. which has a Chloridium anamorph. In the past, all kind of species with very different anamorphs were placed in Chaetosphaeria. So I would say that the Chaetosphaeria species which have a Dictyochaeta anamorph are better placed in Dictyochaeta.

Regards,

Bernard

Re : Chaetosphaeria callimorpha (Montagne) Sacc.
Hi Bernard,

you have a point! But there are also other genera defined over their teleomorphs that have different anamorphs or synanamorphs.

Maybe DNA will tell.

Martin
