New record of genus Peziza in Egypt
Hello,
thank you very much for sharing your publication with us.
However I have to admit, that I don't see how you come to the determination of your fungus. Peziza repanda is commonly seen as a synonym to Peziza varia (e.g. HANSEN et al. 2002). Of course one needs not to be the same opinion (I'm neither ...), but you should have discussed it. Moreover you have a subset "Description and discussion", but besides a brief description there is no discussion at all. I would have e.g. wished to have a discussion about the excipulum, which you say to be a textura angularis. But the varia-group (including P. repanda) has a well differenciated textura intricata in the middle of the fruitbody. The spores you show are mounted in cotton blue (I suppose) and are shown in phase contrast. It has a little bit the look as if there are oil inclusions inside, but one can not say definitely. In the description there is no comment on oil drops in the spores, though this is a very important feature. So may be we can assume there there are none. If you would have made a foto of the spores in water, it would have been clear. Cotton blue is only for observing ornamentation on the spores. it is NOT recommended for other things, especially not for measurements. So measuring 100 spores etc. (did you really measure 100 asci and paraphyses???) is a good thing, but measuring elements in cotton blue makes it uncomparable, as the lactic acid in the cotton blue deformes the spores.
Sorry for the criticism, but I have to admit that I think the decription of the specimens is not clear enough to decide what species you had there. May be P. repanda, may be not.
best regards,
Andreas
in agreement with you Andreas, thank you for asking these questions.
