Hypocreales?
Masanori Kutsuna, 22-05-2012 02:18
Dear everyone

I am a Japanese amateur mycologist, this is my first post in the forum.
Last summer, I found some pyrenomycetes on decaying wood, probably Quercus sp.
Stroma superficial, cushon-shaped, 3-8 mm., pinkish, roughtened with bullet-shaped purplish-brown projections of  ostioles.
Perithecia immerced at different levels, 270-320 ???m. in diameter.
Asci cylindric, IKI-, 8-spored, uniseriate, 2.8-3.2 x 34-42 ?m.
Ascospores subglobose, hyaline, smooth (minutely punctate?), 2.2-2.6 ?m.
I don't know a genus for it.
Can you help me?

regards,
Kutsuna

Re : Hypocreales?
Hello, Christian

Thank you for your reply.
I think, Hypocrea is characterised by perithecia in the upper part of the stromata, and bicellular ascospores disarticulating in the ascus to 16 spores.
Is their any Hypocrea species that perithecia arranged at different levels such as my fungus?

regards,
Kutsuna

Re : Hypocreales?
Hi Kutsuna,
welcome on the forum with this very unusual fungus.
I am thinking of Amplistroma, a new genus created by Sabine Huhndorf et al (2009) Mycologia 101: 904-919. The combination of small fleshy stromata with projecting ostioles, polystichous perithecia and cylindrical asci with hyaline minutes globose ascosopores matches well this genus.
Amplistroma carolinianum, known from USA, fits fairly well your collection but you should ask confirmation from Sabine who is a member of the forum too.
Cheers,
Jacques

Re : Hypocreales?
Hello Jacques

It must be Amplistroma!
Thank you.
