Hello,
I would like to ask your opinion on this one: Collected in may 2015, warm deciduous forest, basic soil. Apothecia 3-5 cm in diam., all with distinct, big and perforated stipe. Young ascomata semiimmersed in soil, then cupulate, old ones cracking to lobes (Geopora-like). Receptacle lightly pustulate. Many fruibodies are perforated on the bottom of apothecium.


Medúlla of t. intricata, cca 330-370 um, ectal excipulum of t. angularis, up to 140 um, at the surface becoming t. globulosa, covered with sparse hairs. Hairs hyaline or yellowish, flexuous, about 50-135 (190) × 7-10 um, obtuse, 1 um thick walls.
Paraphyses not exceeding asci, straight, branched, most of them are slightly clavate, sometimes more irregularly enlarged or antler-like branched, but not much.
Sp. ellipsoid or fusiform-ellipsoid, most of them with rather pointed poles, (20) 21,1–24,3 (25,5) × (9,8) 11–12,5 (13,3) um, probably with 2 LBs and some small ones when alive, uninucleate, carminophile. 

Based on microcharacters I think it is Tarzetta catinus. But I never saw such a distinct, almost Jafnea-like stipe on Tarzetta. Something similar is in this Rubén Martínez Gil's collection: http://ascofrance.fr/search_forum/30049 , but not so much developed. If my determination is correct, is this feature common for T. catinus, or rather result of some environmental conditions?
