On Diphasiastrum (Lycopodium) complanatum
Marja Pennanen, 20-10-2015 20:06
Hi,

I collected yesterday Urceolella pani and noticed, that these ones were yellower.
I luckily decided to study them, too.

These are about 0,2 mm wide.
The spores are with two polar droplets, about 5-7x1.5.
The asci are about 30-35x4-5, propably IKI blue.
The hairs are septate (1-3), may be bent, about 20-35x3-5.

A Psilachnum species or something else?

Marja

Hi Marja,
I had this also already on D. complanatum, could not address to him. In the next came Hamatocanthoscapha cf. lariciconis to HOLM et HOLM (1981) "Ascomycetes on Nordic Lycopods", microscopical also according to the Yours.
Regards Peter.

Re : On Diphasiastrum (Lycopodium) complanatum
Hi Peter,

once again I had forgotten that Karstenia article. Thank you for reminding me.

H. laricionis is a good option. The yellowish colour and a bit wide and peculiar hairs makes me wonder, weather these on Lycopodium are an own variation or even species.
