Unknown species on cones
Ralph Vandiest, 16-03-2014 22:00
Ralph VandiestHello,


I found this species a few months ago but had another look at some cones that I kept in a humid box. Frb up to 0,25mm and bright yellow. On cones of pinus sylvestris. Spores 2,5/3x1µm. The link herenunder is a previous post (3 jan 14) about the same imperfect fungi.


http://www.ascofrance.fr/forum/26540/imperfect-fungus-on-cones

Anybody an idea?


Regards,

Ralph

Hello Björn,


Could be.... the only info I have about this species is in Ellis&Ellis. There I see more round spores. Do you have a key of this genus?

regards,

Ralph

Re : Unknown species on cones
Hi to all,
Ralph's collection possess pleurogenous conidia (as Tubercularia), thus it is not the genus Dendrodochium which has acrogenous conidia.

Re : Unknown species on cones
how about Lemalis aurea?

Re : Unknown species on cones
Hello all,

Thanks for your answers. In a mail I got from Thomas, he refers to W.B. Grove in British Stem- and leaf-fungi. Coelomycetes vol. 2 (1937). Here you find the following:

Lemalis aurea Sacc. (= Catinula aurea Lev.), Dendrodochium citrinum Grove).

Excipulum lemon-yellow, urn-shaped with a spreading rim, very fragile, shining outside,
about 1 mm high and broad; margin coarsely dentate with groups of hairs. Spores
very numerous, globose, hyaline, yellow, 1,5-2 µm diam., concatenate, involved
in mucus; sporophores long, cylindrical, branched, about 0.75 µm wide, each
producing a whorl of four branches at the apex. On cones of Pinus silvestris.
& on the wood of the same. (when dry resembles Calloria chrysocoma).

regards,

Ralph

Re : Unknown species on cones
there seems to be a problem with the shape (and size) of the conidia......

Re : Unknown species on cones
I noticed that to in first reaction on Björns mail; In E&E spores are more or less globose...

Re : Unknown species on cones
Hi Ralph
Looks like I have found the same species as you on Pinus cones yesterday.
Sp. oblong 2.9-3.7 x 1.3-1.7 µm; with 2 bodies positioned at opposite ends of the conidia.
Did you come to any conclusion on species back in 2014?
