Lophiostoma?
Jenny Seawright, 28-04-2015 21:58
Jenny SeawrightHello all,

Found on Phragmites australis (?) at the beginning of April - the closest I can get is possibly a Lophiostoma but the spore sizes of my two specimens are smaller and narrower than those given in Ellis for either Lophiostoma semiliberum or L. arundinis.....

Spores in the first examined were 3-5 septate, (20)22-29 x (3)4-5 µm, measured asci 80-90 x 10 µm.
The second specimen had spores 3-septate, (24)30-40 x (3.5) 5 (6)µm, measured ascus 130 x 10µm

Once again help much appreciated!
With regards,
Jenny

Re : Lophiostoma?
Hi Jenny
with the pseudothecia growing like that - in lines - you could consider Lentithecium arundinaceum. See Enrique's page at http://www.asturnatura.com/fotografia/setas-hongos/lentithecium-arundinaceum-sowerby-k-d-hyde-j-fourn-ying-zhang-2/15260.html It's not always easy to see them but there should be blunt hyaline tips (from a sheath) visible on at least some of the spores.

best wishes
Chris

Re : Lophiostoma?
Thanks Chris,

Comparing with the images shown on Enrique's page Lentithecium arundinaceum looks a good possibility - I'll check my specimens tonight and see if I can find any hyaline tips on the spores.

Are there other names it is known by as I can't find Lentithecium on either the NBN or the BMS's Fungal Database?

With regards,
Jenny

Re : Lophiostoma?
Hi Jenny,
this very common and variable fungus was used to be called Massarina arundinacea before being transferred to Lentithecium.
Cheers
Jacques

Re : Lophiostoma?
Thanks Jacques - Massarina arundinacea was on my list of possibilities but for some reason I'd discounted it .......

With regards,
