Re : cf. Lambertella from Puerto Rico
Excipulum is prismatic? Sclerotiniaceous fungi usually don't have such small spores, and the apical ring is perhaps not really sclerotiniaceous.
Are the macros from fresh apothecia or rehydrated? Was the colour originally such brown?

Hi Danny
Maybe it's a Moellerodiscus... What about croziers? If not, I would consider Ciboria (Moellerodiscus) aestivalis, though spores are a bit short...
Un saludo,

Re : cf. Lambertella from Puerto Rico
Livinjg spores of M. aestivalis s.l. measure about 7-10 x 2.2-3.
Imprtant is to look at the excipulum, Moellerodiscus has a globulosa.

Re : cf. Lambertella from Puerto Rico
Thank you both for the replies. I can check when I'm next near my fungarium to see if this collection was saved, and if so, will check the excipulum and presence/absence of croziers, as you suggest. In the meantime, I will alert Kurt Miller (prolific PR collector) to be on the lookout for similar material. Regarding your first question, Zotto, this material is fresh, not rehydrated.

Re : cf. Lambertella from Puerto Rico
But the micros are all in dead state, perhaps due to the mounting medium, including suqashing, perhaps because only the macros were in fresh.
