Cistella on wood of Fagus sylvatica (not Pinus sylvestris)
Maren Kamke,

Good evening,I found a Cistella sp. on decaying coniferous wood, hairapex capitate, granulate, Asci with croziers, up to 52 µm long mostly shorter than 50 µm, IKI+ blue, spores 1celled, with oil content 0-1, 7,5 x 2,7 µm, paraphyses cylindrical.
Thanks for your help
Regards
Maren

Re : Cistella on wood of Pinus sylvatica
Hallo Maren
as a working name I can offer C. granulosella (= Clavidisculum karstenii), although I know it only from angiosperm wood. But C. dentata is very similar.

Re : Cistella on wood of Pinus sylvatica
Hallo Maren and Zotto,
another idea is that it is Ciliolarinia laetifica in the sense of the enlarged species concept of Raitviir & Huhtinen (2002)

Re : Cistella on wood of Pinus sylvatica
Hmm, what I see in my folder of C. laetifica is longer cylindrical hairs and shorter, fusoid, biguttulate spores.

Re : Cistella on wood of Pinus sylvatica
the collections with biguttulate spores and asci IKI- are to my opinion C. ligniseda. Raitviir and Huhtinen did enlarge the species concept with collections that have IKI+ asci and spores with lower oil content. (unnamed species to my opinion)

Re : Cistella on wood of Pinus sylvatica
Ciliolarina is a mess. For HB 8066 (IKI-) I wrote first cf. neglecta, but you said it is probably laetifica. Now you say ligniseda...
But I meant also the folder IKI+ which includes such broad fusoid spores with +/- oil content, size 4-6.5 x 2-3.
Maren's find goes up to 9 and has 7.5 as middle.

Re : Cistella on wood of Pinus sylvatica
Thank you Zotto and Stip,
I thought also of C. granulosella, had only doubts about the slightly larger spore-width. In the literature the maximal spore width is 2,5 µm.
The mesurements of my find don't fit for Ciliolarinia laetifica. Cistella dentata has larger dimensions overall.

Re : Cistella on wood of Pinus sylvatica
Yes, Ciliolarina should be disentangled, probably it contains several more species.
indeed this sporelength excludes laetifica.

Re : Cistella on wood of Fagus sylvatica
I examined the wood under a microscope and a wood specialist identified it as Fagus sylvatica. Maren

Hi Maren,
That explains the Cistella and not Ciliolarins
Cheers
