When mature, the
ascomata open irregularly to expose the bitunicate, globose to subglobose asci, elliptic to claviform, sessile.
aestivum, produce
ascomata with a basal cavity and, in others, the relative amount of phenoliccomponents is rather high"; 3) about ascospore shape, Riousset et al.
Classification of desert truffles including birds' truffles was based on morphological characters such as morphology of
ascomata, spore, peridium, sporocarp odor, as well as color of the gleba.
Ascomata were rehydrated in 5% KOH prior to examination and sectioning.
ostreatum have ascospores oblate, brown, 5-8 x 4-5,5 [micro]m, with an equatorial germ slit,
ascomata thick walled.
Supported by subculturing on oatmeal agar with Lupinus sp., orange-brown to copper-colored fruiting bodies developed until day 8 (Figure 2b); after 14 days of incubation, these bodies were identified as perithecial
ascomata (diameter 200 [micro]m-300 [micro]m).
Differs from Lophiostoma vicinum in the larger size
ascomata with a small ostiolar papilla, smaller ascus 97,5-113 x 9,8-13 [micron]m with ascospores 19,3-24 x 6,5-9 [micron]m, dark brown, densely verrucose walled.
Nevertheless, the taxonomic importance of the colour of the centrum of
ascomata is not yet clear.
minima, the first observed phase of its cycle was the anamorph belonging to Acremonium sp., then the culture developed
ascomata Our specimen agrees with the original description and with that by Wright et al., (1971) from Argentina.
