Re : Cyathicula cyathoidea???
Did the apos have any marginal teeth? Were they long-stalked or not?

Re : Cyathicula cyathoidea???
Hi William/Zotto

I wonder if this could be Crocreas (Cyathicula) cyathoideum var. cacaliae, which can apperently have larger spores than the type and larger than given in E&E.

I found something that looked similar in the UK in 2013 with spores of up to 19.75, measurements taken from spore print - this is essential as they can be larger when simply squashed from the asci. Ref. was the Monograph of Crocicreas by S. C. Carpenter 1981 but I do not actually have a copy so cannot check the full spore range given for the variety.

C. cacaliae in Carpenter has spores (5)9-14(17) x (1.5)2-2.5(3) µm. The present ones are 15-16 x 2.7-4 µm. Also, C. cacaliae has a low oil content while this one has a very high content.

Dear Zotto,

this is a very tiny species.
The apotheciahave no marginal teeth and they have a stalk as long as the cup.
Pictures are x100.

Re : Cyathicula cyathoidea???
It is quite rare that C. coronata occurs without teeth, or possibly it is a separate species, but this is unclear and perhaps undescribed.
