Suprice on Typhus
Marja Pennanen, 28-05-2010 13:51
I picked some pieces of Typhus (or other damp place big grass) some time ago. There seemed to be some white growing. I forgot them to refrigerator and was emptying boxes yesterday. I noticed these on the leaves.
They have turned brown, are hairy and about I mm wide.

Re:Suprice on Typhus
The spores are about 5-7x2-2,5, asci 37-55x5-6, IKI+.
Paraphyses are lanceolate, 4-5 micrometers wide and 15 exceeding the asci.
Hairs are about 20-40x4-5 and the tips look like cactuses.

Hi Marja

Typhus and cholera! Don't know what that is. Paraphyses resemble Psilachnum, but hairs???

Again, the excipulum could perhaps help to find a genus.

Re:Suprice on Typhus
Dear Zotto,

huh, luckily I have a photo, which instead of hairs (which I tried to shoot) shows cells :)

Marja

By the way, I think I saw something more at the tips of hairs, but couldn't find that after pressing the specimen...

Re:Suprice on Typhus
A globulosa and lanceolate paraphyses... I remember the genus Mollisiopsis which is perhaps not more than a Mollisia with lanceolate paraphyses, but without guaranty. Maybe you get a yellow reaction of the VBs when you add KOH?

Marja Pennanen, 28-05-2010 15:42
Re:Suprice on Typhus
Ok,
I'll test that after making rhubarb pie.
Some of Mollisina hairs resembled these hairs.
I've got no information of the genus Mollisiopsis :(

Re:Suprice on Typhus
I am perhaps wrong because Mollisiopsis lanceolata is a Pyrenopeziza. Mollisia clavata on Rubus has a tendency to lanceolate paraphyses.

Maybe Andreas knows something.

Re:Suprice on Typhus
Hello,
I got no yellow reaction, but on the other hand my KOH may be too old.
What I saw was some more hairs. They can be clavate, septate and size even 60x6 micrometers.
I saw some crystals, but they can come anywhere, because I meshed in sampling, The specimen was drying and hard to handle.

I'll send this to Seppo one day with some other interesting species. If this is a Mollisiopsis it would propably be a new genus for Finland-or maybe not...

Re:Suprice on Typhus
Hello again
I've got a suggestion of Hysterostegiella-genus for this.
There even seems to be H. typhae species.
Naturally I've got no information of the genus or species :(

Anyway determination is proceeding...

Re:Suprice on Typhus
Hi Marja

yes!! there is even the lateral epidermial lid visible on your photo, by which the young apos are covered.

The species is redescribed in Hein 1983: 684,and a distribution map shows that it was only known from some finds in eastern Germany.

The only probvlem is that Hein keys H. typhae with apothecia min. double as long as wide. Perhaps herbarium material does not swell enough? Or he gained this character from the dry state as h referred to his REM image with half closed lid.

That's fine! the epidermial lid is elongate, like Hein reports.
