A coriaceous pseudo-bombardioid ascomal wall containing a central layer composed of thick-walled, gelatinized cells has been described in nine species in the Lasiosphaeriaceae (Sordariales). Three different methods of sectioning ascomata were employed to investigate the composition of this wall layer. Although this wall layer has previously been described as being composed of isodiametric cells, sections made using a freezing microtome revealed that it was actually composed of interwoven hyphae. Thus the term pseudo-bombardioid should be emended to describe a non-stromatic ascomal wall containing a gelatinized layer composed of interwoven, thin-walled hyphae.
