Already by that time I had a good knowledge of the plants in Silesia and certainly around my village, I knew everything that was growing there. In fact me and a few other enthusiasts from this school, with Karel Kousal, were roaming the countryside looking for new species.  New, of course, not in the sense that it would be new to science, by that time it was all known what was growing in the whole Czech Republic, but species new for us that we never saw before and you cannot imagine, or a person who has not had this experiences cannot imagine, what a delight it is to come across a new species of this kind. One of my major findings of the new species was actually a plant... was a mushroom, scientifically its called Geastrum and the English name is Earthstar. It's a kind of a puffball except that it... the ball is actually... consists of two layers, one of which, the outer one eventually breaks and opens and breaks in such a way that it forms lobes, that when they open completely look like a star.  So the star is spread out on the floor, on the ground and here in the middle is the ball, so it's a puffball. At least in the part where I was born it was very rare mushroom, so I knew it from some magazine where somebody in Prague was advertising that anybody who finds this mushroom should contact him because he was making a monography... writing a monography on this particular genus and he was interested in their distribution. I... when I was going through the woods and suddenly I saw this wonderful, beautiful Geastrum there on the ground; this is an experience you cannot describe, it was just wonderful. And so I could not wait until the next morning and will go to school and show it to the teacher. The teacher actually then contacted this person in Prague and not only that, he wrote an article about it because in the meantime we found some others also in some other places and how proud I was, my name was mentioned in the article, that Jan Klein... pupil Jan Klein found this in the village of Štemplovec and was showing everybody in the family. This is my first scientific contribution to be mentioned in... in an article.
