 Relative to other typical mushroom species , the spores of V. bohemica are huge , typically measuring 60 – 80 by 15 – 18 µm . They are elliptical , smooth , sometimes curved , and appear hyaline ( translucent ) to yellowish . The spores , which number two ( more rarely three ) per <unk> are characteristic for this species . The smooth , elliptical asci measure 275 – 350 µm long by 16 – 23 µm wide . The British @-@ Canadian mycologist Arthur Henry Reginald <unk> determined that the asci are <unk> — they bend toward light . As he noted , " I cut transverse sections though their <unk> , examined these sections under the microscope , and at once perceived that in all the <unk> grooves and depressions the asci were curved outwards so that their <unk> must have faced the strongest rays of light to which the ends of the asci has been subjected in the places where the fruit @-@ bodies developed . " This response to the stimulus of light is significant because it permits a fruit body to point and later discharge its asci towards open spaces , thus increasing the chances that the spores will be dispersed by wind . The paraphyses are thick and club @-@ shaped , with diameters of 7 – 8 µm at their tips .
