While doing the microscopy I realise that the data point to the genus I mencioned in the notes of Observation 363710: Coenogonium. However, after sometime, I saw that the spores were consistently 3-septate. Consulting the British Flora, I saw that the genus has two species as British represetatives: C. luteum and C. pineti, both having 1-septate spores. I also saw the usual websites and all of them mention 1-septate spores for Coenogonium spp., some presenting micrographs. In despair, I looked to the Sonoran Flora and “EUREKA”: the species C. luteum is described as having 3-septate spores; that description is available in CNALH. I wonder if we are considering the same species or if the spore septation is a variable within the species.

Dimensions of the spores: (9) 10 – 15 (16) × 2.8 – 4 µm
