Does anyone know any hypogeous Helvella?

Helvella are epigeous fungi but these Helvella live entirely underground and they are fully mature underground. Macroscopic and microscopic features, at maturity, are like Helvella costifera: irregular cup-shaped, 2-9 cm broad, up to 9 cm high. Asci 250-300 x 13-15 µ, paraphyses 3-5 µ, spores 15-16 X 10-12 µm Q=1,33-1,60
Habitat: Hypogeous under Quercus ilex subsp. ballota in clay and limestone soils. Mars through May

¿Alguien conoce una Helvella hipogea?
Hola,
El género Helvella está formado por especies epigeas, pero esta Helvella completa su ciclo completamente hipogea. Nos la encontramos todos los años en terrenos arcillosos y calizos, bajo Quercus ilex subsp. ballota, desde marzo hasta mayo. Detectamos su presencia por los bultos y las grietas que hace en el terreno, pero nunca hemos llegado a verla fuera de la tierra.
Su aspecto macroscópico y microscópico es compatible con Helvella costifera: forma de copa irregular, 2-9 cm. de ancho, hasta 9 cm de alto. Ascos: 250-300 x 13-15 µ, paráfisis 3-5 µ, esporas 15-16 X 10-12 µm Q=1,33-1,60.

They are Helvella semiobruta Donadini & Berthet 1976

Re : Does anyone know any hypogeous Helvella?
Helvella semiobruta cannot be considered as a hypogeous Helvella nor H. costifera. The only species which is really hypogeous is Helvella astieri Korf & Donadini.

Re : Does anyone know any hypogeous Helvella?
J'ai toujours récolté H. semiobruta quasi enterrée et une seule récolte d'H. astieri qui était épigée
I always harvested H. semiobruta almost buried semiobruta and a single harvest of H. astieri who was épigéeous

Re : Does anyone know any hypogeous Helvella?
Thanks for the opinions,
I did not know neither Helvella semiobruta nor Helvella astieri, but they look very different from my Helvella.
I think the hipogeous habit of this Helvella is an adaptation to dry habitats where it grows.
A future truffle!

Gracias por las respuestas,
No conocía ni la H. semiobruta ni la H. astieri, pero son muy diferentes a mi Helvella.
Creo que el desarrollo hipogeo de esta Helvella es una adaptación a un hábitat demasiado seco para una Helvella.
¡Un futura trufa!
