Hans-Otto BaralDoes anybody have this article?
Pustularia insignis Berthet & Riousset, Bull. trimest. Soc. mycol. Fr. 79(3): 397 (1963)

I want to know whether Hypotarzetta insignis has croziers, or rather simpe septa (forked ascus base) as in Tarzetta.

Hallo Zotto
Welcome to operculates, true discomycetes. here is the article.
Nothing about croziers but drawing makes me believe there are not.
cheers

Re : Hypotarzetta
Thanks indeed, Francois!! The drawing clearly shows simple septa as in Tarzetta.

Also Martin gave me links to a Nicolas drawing and a good article by Häffner 1992.

I am going to leave true discomycetes now, glad to have clarified everything about them :-)

Hi Zotto,


There is also a recent paper mentionning the 1rst collection of H. insignis for Alsace by F. Sarraillon in the Bulletin de la Fédération Mycologique de l'Est. (2013)


The author clearly mentions no croziers ascus but there is no micro picture.


Amitiés

Re : Hypotarzetta
Thank you all for this help and offer. In order to show you why I asked my question, here is a small part of the text that I am writing for the new Syllabus edition on the families of plants and fungi. The below text treats a small group that is presently in the Pyronemataceae and was earlier partly in the Otideaceae, but forms a clade of its own and seems to be characterized by simple-septate asci. Since I need to cover all true and untrue discomycetes, I cannot spend time to look at material. I even fail to look at all relevant literature, even if I have it. So I am happy whenever I get suggestions and corrections to any group of the discomycetes.

Geopyxis-Tarzetta lineage 6 gen. (c. 32).
Geopyxis (Pers.) Sacc. (7) – Hydnocystis Tul. (?4, clthec.) – Hypotarzetta Donadini (1) – Paurocotylis Berk. ex Hook. (?4, clthec.) – Stephensia Tul. & C. Tul. (7, clthec.) – Tarzetta (Cooke) Lambotte (also Tazzetta, Pustularia Fuckel, Pustulina Eckblad) (9),

This lineage forms a sister group to Ascodesmidaceae and Pulvinula. The 3 cleistothecial genera are genetically related to Geopyxis. Remarkable is the frequent absence of croziers (verified for Geopyxis, Hypotarzetta, Tarzetta, and Hydnocystis). - References: Alvarado & al. (2011), Häffner 1992, Healy & Smith (2009), Laessøe & Hansen (2007), Perry & al. (2007).
