Asco on Salix
Perz Piotr, 19-10-2007 02:12
Hi,

this is Pezicula-like fungus on bark of Salix, growing under Periderms, breaking off the bark (like Pezicula, but not in clusters).

Sorry, I have no good Makros :(

Re:Asco on Salix
Something close to Amyloprop. octom. 1, HB 6690 from Zotto's DVD ?

best wishes

Re:Asco on Salix
Hi Piotr

when I look at the marginal excipulum of t. porrecta, with very short, irregularly curved smooth hairs, I see some similarities with Calycellina ochracea, a species which I put close to Rodwayella. However, these fungi around Rodwayella have very striking yellowish VB-guttules in paraphyses and hairs, while yours appears to be devoid of these. Also the apical ring reacting only in its lower part looks different.

I suggest a relation to Hyaloscypha s.l., but have no idea what species this is.

How large are the spores? Perhaps I find something in my database. Probably this is a xerotolerant fungus and therefore perhaps one of those many undescribed ....

Re:Asco on Salix
Hallo / Hi !

Thanks Zotto. The spores in vital state are (33) 35 – 39 (40) x (9,2) 9,5 – 10,5 (11), curved.

Calycellina, Hyaloscypha ? My species is growing from erumpted bark and on hymenial surface does have refr+ exsudate - all like by Propoloid fungi.

Re:Asco on Salix
Hoi Piotr
yes, now I see it more clearly, forget my previous suggestion. The fungud seems erumpent, and I suggest you to compare my genus Amylopropolis nom. prov. (in directory "Rhytismatales, propoloid fungi"). Would that be a better choice ? :-)

ThisAmylopropolis is, however, a Macaronesian collection... And it does not seem to form longisepta in the spores which I found consistently with 7 cross septa.

Re:Asco on Salix
OK Zotto,

that was also my sugestion, see below (le 19/10/2007 à 02:21). It can be a next species in this genus, cause is seems to be very close to this fund from Croatia.

Tschüss!

Re:Asco on Salix
Hey, sorry, I must have overlooked your line above the macrophoto. Wonderful that we finally arrive at the same result!

This unpublished genus (if a separate genus at all) is very interesting because it undoubtedly represents a close relative of Propolis and Melittosporiella, but is, to my knowledge, the first report of a Rhytismatalean fungus with amyloid asci, as far as placement of the propoloid fungi within that order is supported, but at least it seems to be the first record of amyloid asci within the propoloid fungi.
