marcelleina key?
DirkW, 02-11-2010 18:14
DirkWsalut a tout,

i have problems here with a marcelleina. the ornamentation is very similar to that of lamprospora seaveri ...
could anybody send me an actual key of marcelleina? i only have nordic macromycetes and ellis for this genus and i am not aware of the contemporary number of europaen taxas.

best to all

Re:marcelleina key?
That is maybe M. rickii, if there is a complete reticulum, perhaps you can send me your finding via email ;)

Re:marcelleina key?
hi kazuya,

rickii should have an incomplete reticulum, if i remember right. sorry, i cant send you images. unfortunately the interesting collection (only one very small apo, found by someone else on a seminar) got lost. i only saw it makro- und mikroscopic one time ...
but a key with actual taxa (mediterranae etc,) would help ...

viele grüße

Re:marcelleina key?
Cher Collègue,

M. persoonii (H. & P. Crouan) Brummelen possède des ascospores avec un réticulum presque complet. Je vous adresse la clé du genre Marcelleina, proposée par Moravec, demain.

Cordialement

René

Re:marcelleina key?
cher rené,

thank you so much! this is very helpful to me, especially les planches de dessins! according to this, it has to be persoonii in the sense of moravec ...

2010 a new taxa was described in mycotaxon (januar - februar) by Lantieri, Angela; Pfister, Donald H.!: "Marcelleina mediterranea is described as a new species and is illustrated. It occurs on sandy soil among scattered mosses, in Southeast Sicily (Italy). It differs from other species in size and ornamentation of ascospores. Its ecology and taxonomical relationships are examined."

i will try to get the article as soon as possible ...

schöne grüße
