Jason KarakehianHi, Ascofrance community. Any help with this would be greatly appreciated. I think that this is a species of Julella? Collected on Salvia leucophylla (Atudibertia nivea), California, USA in 1939. I've also encountered this before from the east coast of the US from Massachusetts. The macrophotos of the specimen are from hydrated material. Asci are iodine negative in 10%KOH > h2o rinse > IKI. It appears to be a perithecium(?) immersed in the wood, with a highly pigmented covering layer composed of woody tissue and hyphae. The ascomata dehisce by an irregular tear in the covering layer, but the perithecium dehisces via a pore. There is usually one perithecium per ascoma, sometimes 2-3, but these are never confluent. The top of the the perithecium and the top of the covering layer are attached, but in hydrated material the covering layer can be easily removed with a probe and the perithecium teased out. The perithecium wall is composed of elongated cells like textura oblita. No algae were observed around the ascomata, and they usually arise within somewhat bleached wood.
