Cheilymenia sp. on burnt ground and dead animal debris
Stephen Martin, 06-11-2024 11:59
Stephen MartinI am trying to identify a Cheilymenia sp. using keys by J. Moravec (1984) found on burnt ground and plant debris (and there was also some dead reamians of fowl)

My first problem is if the spores are striated or not, and in some images stained in cotton blue, I can make vague striations but they can be shadows not striations. I am assuming that they are fine striations and hence attribute the species to Sect. Striatisporae (which include some species that grow on plant debris). The hairless apothecia would lead to  be Sect. Coproba and easily keyed to C. granulata, but this is a dung species and excluded for that reason.


Further info:


Excipulum (medullary): Spherical to broadly elliptical usually with obtuse angles forming an isohedral, 30-48 µm wide
Hairs on rim: A few present, scattered, quite inconspicuous and hyaline
Hairs length: (150–)200–400(–450)µm
Hairs morphology Hyaline, straight, sometimes with a swollen tip (or swollen just below the apex) 1- or 2- septate (depending length of hair) with a bulbous basal hypha, ovoid and asymmetric and with a septum just above the base and sometimes a second septum located about the proximal third of the hair length.


Ascum average size 215.3 µm x 12.3 µm
Iodine reaction J -ve
Spore average size 15.2 µm x 8.7 µm
Spore Q factor 1.71


I am inclined over C. theleboloides s.l. likely f. glabra for being almost hairless and which grows on wide range of habitats (and the text says easily confuses with granulata mentioned above !)
