Anamorph on Tilia
Gernot Friebes, 24-02-2026 11:01
Hi,

found on a branch of Tilia, with conidia measuring approx. 2.8-3.7 x 1.9-2.0. Thank you for any ideas.

Best wishes,
Gernot

Re : Anamorph on Tilia
I think this is Bloxamia truncata (probably not rare but certainly under-recorded). They seem to be anamosphs of Calycina-like fungi.

Best wishes

Re : Anamorph on Tilia
This is a Bloxamia and the anamorph of Calycina discedens / C. claroflava.

Re : Anamorph on Tilia
Wu & Diao 2023 combined Calycina discedens into Bloxamia, describing the anamorph with smaller conidia than those of C. truncata, but all of their collections came from China so may not be conspecific with the type.

Re : Anamorph on Tilia
Thank you, Paul and Zotto!

Do you know if C. discedens and C. claroflava are synonyms? Wu & Diao (2023) say that they are not, citing papers by Karunarathna et al. (2021) and Hosoya & Zhao (2016). It would not be surprising if they were different since C. discedens was described from Brazil and C. claroflava from Great Britain. Can we therefore assume that my anamorph is C. claroflava?

Best wishes,
Gernot

Re : Anamorph on Tilia
Available sequences fall in two groups at least, with about 5% ITS distance, speaking for at least two species.

C. discedens is +/ indistinguishable from claroflava, having inamyloid asci and 1-septate spores. European claroflava (= Helotium citrinicolor Crouan, the type of which I have examined) has asci without croziers, but I have seen that also in the Brazilian type of Ombrophila microsperma Hennings, which Dumont identified as B. discedens. I am not sure if a difference exists in ascus and spore size.
