Lepista ZacariasHello everyone, Does any one know of any literatu
Ascas amiloides, octospóricas, de 230-240 x 12-13 micras.
Esporas elipsoidales, hialinas, lisas, no gutuladas, de 16 x 11 micras.
Paráfisis rectas, con el ápice algo ensanchado, septadas, rellenas con material granular.
Me han planteado la posibilidad de una Arpinia, pero estas no poseen las Ascas amiloides.
Alguna otra posibilidad
Hello,
as you write an Arpinia can be excluded because of the iodine positive asci. This is a Peziza - what else? The ecology and appearance would be near P. cerea agg. ("muralis", ....). I do not know how is the actual taxonomy in this (difficult) group. Maybe somebody else can say more.
