Peziza on sandy soil
Manak Roman, 30-11-2019 20:24
Dear all,

I need help with this Peziza.

I found it in a sparse grassland on sandy soil. The fruiting bodies with short stem had a diameter around 5 cm, the color was ocher with a light olive shade on hymenium and in places slightly pink on the outside.

Spores with (1)2 guttules in water: M = 12,0-15,5 × 6,6-8,7 µm, Q = 1,5-2,1. Ornamentation warted/irregularly reticulate.

Asci: 160-215 × 10-13,5 µm.

Paraphyses had twisted apices and diameter 3,4-5,2 µm

Thanks a lot for any suggestions

Roman

Re : Peziza on sandy soil
Hi, Manak - 


do the asci blue in Melzer's Solution? If not, check with Sowerbyella.

Hi Till,

thank you. I forgot to check asci tips in Melzer. I'll fix the mistake tomorrow.

I agree, this is a Sowerbyella.

Re : Peziza on sandy soil
Thank you for your feedback.

I checked the reaction of asci in Melzer´s and they don´t blue. It is Sowerbyella as you suggested. It is probable S. radiculata according to key of Yao and Spooner and also Moravec´s key.
