Dactylella on Alcea rosea
Karen Poulsen, 06-07-2023 22:25
On last year's stem close to the ground in garden waste.

Hi, this one is TINY and perhaps somewhat unusual.

Single with a single conidia at the tip, hyaline, unbranched, total height 100-150 µm. Conidiophore septated, approx. 2 µm wide. Conidia clavate to fusiform, 3-10-septated, 40-79 x (6.5)-(7)-8-(9), n=18.

Based on illustrations and descriptions in Hans-Otto Baral, Evi Weber & Guy Marson, MONOGRAPH OF ORBILIOMYCETES (ASCOMYCOTA) BASED ON VITAL TAXONOMY I come up with 3 possibilities: arnaudii/oxyspora, panlongana or rhopalota. But no one is spot on! The conidia tease, but could perhaps be one of the two former, if spores are clavate when young?
Thanks alot for any help.

Re : Dactylella on Alcea rosea
Hi, I fear this cannot be definitely answered without culture and sequence. The Neodactylella-group is very difficult, even if we had the teleomorph. At first glance I thought O. rectispora = D. nuorilangana, monograph p. 1451, but the dicot-host would exclude that. Your collection is from Europe? Conidia of D. rhopalota I think do not turn ellipsoid-fusoid. D. oxyspora/rhombispora is more fusiform. D. panlongana is only known from China so far.

Re : Dactylella on Alcea rosea
Thank you so much!

I thought, it would be difficult, so I just have to settle with less :-) Can it be assigned to the genus Dactylella?

The collection is from Samsø, Denmark.

Re : Dactylella on Alcea rosea
As I remember is the type of Dactylella Grove, D. minuta, of unclear relationship. Our broad concept of Orbilia assigns such fungi as yours to Orbilia section Arthrobotrys series Neodactylella. So you can say Orbilia sp. or something like Orbilia aff. rhopalota.
