Orange discs on Arctium
Marc Detollenaere, 10-03-2026 18:08
Marc DetollenaereDear Forum,

On stems of Arctium, I found some downy orange discs with hyaline spores of 22-23x14-15µ , slightly verrucose, no drops. A slight amyloied reaction was seen on the asci.
Could it be Iodophanus?

Re : Orange discs on Arctium
Yes, Iodophanus. The problem is what species it is. Iodophanus has been studied very little.

Marc, Iodophanus verrucosporus occurs in Flanders, see http://www.ascofrance.fr/search_forum/13515 (Piet posted it for me)

Re : Orange discs on Arctium
Dag Lieve,

Met Doveri kom ik inderdaad ook het dichtst bij verrucosporus. Het enige die mij hier doet twijfelen is de kleur van het vruchtlichaam, dat bij verrucosporus bruin zou moeten zijn.Verkleuring door ouderdom?
Met Lugol heb ik nu wel een duidelijke amyloiedreaktie thv de ascustop.

Het substraat van jouw vondst is heel specifiek.
