The meaning of "trabeculate"
Björn Wergen, 28-01-2014 22:17
Björn WergenHi friends,

I have one question: what does the word "trabeculate" mean? Its mostly used to describe paraphyses/pseudoparaphyses. I have problems to decide whether the paraphyses are trabeculate or not...

In latin, trabecula means "beam". I think it could be the connections between the paraphyses/pseudoparaphyses?

Thanks in advance!

regards,
björn

Re : The meaning of "trabeculate"
From Dictionary of the Fungi:
"Hamathecium (Eriksson, Opera Bot. 60: 15, 1981), a neutral term for all kinds of hyphae or other tissues between asci, or projecting into the locule or ostiole of ascomata; usually of carpocentral origin; interascal tissues. Eriksson recognized seven categories (see Fig. 14A-F - below):
(A) Interascal pseudoparenchyma, carpocentral tissues unchanged or compressed between developing asci; e.g. Wettsteinina.
(B) Paraphyses, hyphae originating from the base of the cavity, usually unbranched and not anastomosed; e.g. Pyrenula, Xylaria.
(C) Paraphysoids (trabecular pseudoparaphyses; tinophyses), interascal or pre-ascal tissue stretching and coming to resemble pseudoparaphyses; often only remotely septate, anastomosing and very narrow (see Barr, Mycol.  71: 935, 1979); e.g.  Patellaria, Melanomma.
