Dear colleague,
The first one could be a species from the genus Cookeina. But without microscopical data it is impossible to determine it. The other one is completely new to me, never saw something like that. Ivana
hello Ivana,
what microscopical data is needed to determine its genus or species?
Hi
The second one seems to be Microporus xanthopus, but for confirmation work out the microscopic detail.
Hi,
According to the key published by Pfister & Kaushal (1984) in Mycotaxon 20 (pages: 117-121) for apothecia without distinct hairs you need to look at the ascospores. Describe the ornamentation (if the spores are not smooth), measure ascospores length and width (min. at 10 spores), and try to make a section of the flesh in order to see are there any gelatinous matter in cortical layer. It would be also interesting to know at what type of habitat did you find this Cookeina?

Regards, Ivana
I found this in Tropical rain forest in Indonesia. And I also found the the hairy ones.
Hi Ivana,
your fungus should be Cookeina speciosa
Best wishes
Christian
Thanks Christian, this can help to Agus to determine the Cookeina species.
I do not have the material, just tried to help with reference data.
The red apothecium appears identical to Sarcoscypha occidentalis (Schwein.) Sacc. but this is a fine example of the importance of microscopy for determination of collections.

hi Mr. David, at first glance between Cookeina speciosa and Sarcoscypha occidentalis look similar. but looking further to their shapes and stems, i prefer to Cookeina speciosa. but of course advanced characterization is required.
best regards!
THE FIRST look as Cookeina, but is not enough simple observation, I suggest that you observe spores and hymenium, the second one look as a "turkey" , perhaps Coriolaceae familie...but is necessary confirmation work out the microscopic detail.
The first one resembles Cookeina sulcipes, the second Podoscypha sp. which are very common in the tropics.
Thank you dear Sebastian and Trupti, seems the the answer for figure 1 has been specified. But there still various answers for figure 2 ...
First one is Cookeina - species??. Second one - need more features - can be any of above suggested - including Microsporus
To identify the decibel one, you need to see whether the hymenium is porous (Microporus) or smooth (Podoscypha)
Agree with Maria. It is not often easy to name upto spp level based on gross morphology - in this case plieus view only.
The first one is Cookenia speciosa and the second is more difficult to identified, If the hymenophore is porous may be Microporus with small pores (6-10 per mm), but It could be a Hexagonia if the pores are large (2-3 per mm, I am collected similar specimens in Mexico); and if the hymenophore is smooth, I agree with my collegues, could be a Podocypha.
Thank you Mr. Richardo, unfortunately we cannot identify the hymenophore
Thank you for your help too, dear Maria Paz Nunez and Vikineswary Sabaratnam
best regards.
Is it C.speciosa (said to have hairy margin )or sulcipes? hard to tell based on morphology. But for sure not C.tricholoma ( bristlelike hairs )
Second photograph looks like Microporus xanthopus. Please check the microscopic features and standard literature.
Agreed looks like Microporus - as suggested check microscopic features for species. This is a complex group
Agreed looks like Microporus - as suggested check microscopic features for species. This is a complex group. If undersurface - without spores - and cap is leathery / could Podocypha as suggested by Ricardo.
